One of the most common reasons people increase activity is to burn more calories, create a calorie deficit, and lose weight. A new study demonstrates that this might not work as simply as we think. Using the most extensive dataset on human energy expenditure ever assembled ( n = 1754), researchers demonstrated that increasing activity is compensated by a decrease in basal or resting energy expenditure. So for every 100 calories of additional activity, we only burn 72 calories - a compensation of 28%. This relationship was similar for men and women, young and old. Making matters worse for people seeking to lose weight through increased energy expenditure is the observation that the level of compensation increases with weight. People at the 90th percentile weight (BMI = 33) in this study compensate almost half of their calories. Finally, there is a significant variation amongst people - some compensate more or less than others.  Photo by Shoeib Abolhassani on Unsplash This finding has several implications:
The potential relationship between the increase in appetite associated with increased activity and this energy compensation was not touched upon in the study but has significant real-world implications. The increase in appetite (and consumption) for some people may be equal or potentially greater than the increase in actual calories burned. These combined effects may be why exercise alone generally does not work for significant weight loss. Another potential implication not touched upon in the study is that the compensatory decrease in energy expenditure may have possible health benefits (i.e. decreased immune system activity, decreasing chronic inflammation). This may be one reason why exercise has been shown to have such significant health benefits despite its lack of efficacy for weight loss.  As humans, we are designed to respond to stress through a process called allostasis- “maintaining stability through altering physiologic parameters to counteract challenges.”
We all have a built-in stress response, where the sympathetic nervous system (SNS) activates for short periods to address short-term stressors. When the SNS is in charge, the body prepares for fight, flight or freeze. During this time, adrenaline and cortisol flood the bloodstream, the heart rate increases, digestion slows, and breathing becomes rapid. We are ready for whatever life throws at us! When the stressor passes, the relaxation response - our parasympathetic nervous system - the one responsible for rest and relaxation - kicks in, and our bodies return to normal. This alternating pattern of sympathetic and parasympathetic nervous system activation is the natural cycle that we all experience when encountering stress. But what if the stressor doesn’t pass? Peter A. Levine, a trauma researcher, has studied animals in the wild who are constantly exposed to external threats (stressors). He found that when animals draw on heightened amounts of energy, they have mechanisms to release the excess energy through behaviours such as shaking, running or bucking. Humans, on the other hand, don’t have built-in systems for trauma and stress. Hence, chronic stress over time erodes our resilience. Levine notes that when a stressor never passes- due to either external events or our internal response to those events, the SNS gets flipped and “stays on”- not fully returning to a state of rest and relaxation. The result is called allostatic overload and directly connects to a decline in physical and mental health. Fortunately for us as humans, we have other mechanisms to counter stress - beyond that of animals. So next time you feel that your body and mind are in a heightened state, being overrun by your SNS, try these tools to reset: 1. Breathe Breathing is the only part of the parasympathetic nervous system that we can control as humans. Resonant Breathing- deep breathing in and out at a methodical pace (3-7 breaths per minute) has been shown to improve symptoms of depression and anxiety. 2. Take a Walk In Nature: Shinrin-Yoku is the ancient Japanese tradition of walking in the forest while engaging the senses. The English translation- forest bathing- has become popular in treating various lifestyle diseases and has been shown to improve immune function and promote an overall sense of calm. 3. Fill your plate with Healthy Whole Foods: Research on ‘food and mood’ has linked specific nutrients- such as Omega 3s- found in fish, walnuts and soybeans- to improved mental health. Other foods such as whole grains, colourful veggies and fermented foods support a healthy gut and microbiome. Growing research points to the role a healthy gut plays in maintaining mental health. Check out our EATBetter guide. 4. Move, Move, Move: Just 150 minutes of moderate to vigorous exercise a week is linked to a greater sense of well-being. In some studies, exercise has been shown to be as effective as medication in treating depression and anxiety. . .need we say more! Check out our LEVELUp your fitness guide. 5. Practice Mindfulness in the moment: Focus on where you are in the moment, rather than allowing the “what ifs’ of life to constantly creep into your daily thoughts. When you find your mind wandering or, in some cases spiralling- allow yourself to come back to the present moment by focusing on your five senses. Look at what you see, listen to what you hear, feel your feet on the ground, take a deep breath, smell your surroundings, and taste what is in your mouth. Check out the countless mindfulness apps to help you develop and deepen a mindfulness/ meditation practice. Finally- be sure to give yourself scheduled time to get a break from the constant stressors of life - take a bath, go for a walk, read a book, spend time with loved ones, take a holiday!! Wellness Garage will be closed from August 23rd- 29th. We look forward to seeing you again- well-rested and rejuvenated!

Post-traumatic stress disorder is a severe psychological condition that develops in response to traumatic events that often leads to chronic, disabling symptoms lasting years or decades after the trauma. PTSD is characterized by intrusive flashbacks, interrupting thoughts, nightmares, sleep disturbances. Avoidance of activities, relationships or thoughts that stimulate memories of the trauma can lead to irritability, isolation, guilt and depression. A recent study estimates that 1 in 3 RCMP members currently have PTSD - almost four times the general population’s lifetime prevalence. Effective treatments are available, including counselling, psychotherapy as well as medication. Unfortunately, many people with PTSD have residual symptoms resistant to treatment and lead to long-term disability. Current treatments all focus on psychiatric manifestations, with little to no emphasis on the metabolic and cardiovascular risk factors associated with PTSD. An emerging body of evidence shows that PTSD is a significant risk factor for metabolic dysfunction with higher rates of obesity, high cholesterol, high blood pressure, diabetes and heart disease. The precise mechanism by which PTSD increases the cardio-metabolic risk has not yet been determined, but emerging evidence suggests that the link between stress and metabolism is central. Stress, mediated through the sympathetic nervous system (“fight or flight”) and the hypothalamic-pituitary-adrenal (HPA) axis, leads to higher levels of the stress hormone cortisol. Chronically elevated cortisol levels result in abdominal obesity, which leads to insulin resistance and inflammation, the underlying processes that drive the risk of diabetes and heart disease. Cortisol also drives over-eating with increased consumption of comfort foods - high-calorie food choices. Compounding these effects of stress, people with PTSD show changes in brain function associated with appetite and changes in reward-processing that make the over-consumption of high reward foods even more likely. Our brain recognizes foods with these characteristics as innately rewarding:
Not surprisingly, research shows that individuals with PTSD have poor dietary habits and higher rates of emotional eating related to PTSD symptom severity. For some people with PTSD, the positive stress of exercise, with adrenaline release, increased heart and respiratory rates, can trigger PTSD symptoms. As a result, these people avoid exercise to minimize the risk of recurring effects of PTSD. The result is a more sedentary lifestyle that only further aggravates weight gain and poor metabolic health. Finally, the symptoms of PTSD often present with nightmares and disturbed sleep, further aggravating the stress response. The weight gain and metabolic changes increase the risk of developing sleep apnea, setting up another vicious cycle. How to address this? PTSD requires a comprehensive treatment plan, often combining counselling and medication. Often overlooked are the benefits of intensive lifestyle interventions to combat the effects of PTSD on diet, exercise, sleep and overall stress. Recognizing metabolic dysfunction, insulin resistance, pre-diabetes or diabetes and applying proven lifestyle approaches (like the 4+2 Diabetes Reversal Strategy) not only improve overall health but are synergistic to the primary therapy for PTSD. For RCMP: Wellness Garage offers a fully funded, comprehensive, year-long, multi-disciplinary lifestyle medicine program to help members with weight loss, nutrition, fitness and lifestyle optimization. The program is ideal for members with PTSD to pair with their psychological care plan. The program’s criteria are weight-based: BMI >30 or BMI 27-30 with a weight-related diagnosis. Although PTSD has not traditionally been thought of as such a weight-related process, the emerging evidence presented in the literature and reviewed here suggests that it should be recognized as such. Click here to learn more about this program. Even if you don’t qualify for the funded program - please reach out to have a Lifestyle Medicine Assessment (funded through MSP), where we can assess risk and help you develop a lifestyle strategy.   Photo by Kinga Cichewicz on Unsplash When it comes to your sleep, answer these four questions:
If your answers are yes to 1 and 2 and no to 3 and 4 - you do not have a sleep issue. You may be able to improve your sleep quality by falling the recommendations in 'How to Improve Your Sleep'…but feel fortunate and turn your efforts to one of the other pillars. You will notice that none of the questions here talk of time asleep or amount of deep sleep, REM, or any of the sleep scores you can derive from the variety of sleep trackers. If you sleep soundly and full of energy, you do not need to track your sleep. Even if you track your sleep - your answer to these questions is more important than any metric derived from a sleep tracker. If your answers are not optimal, you will want to improve your sleep habits while assessing yourself for sleep apnea or other sleep disorders. Use the Wellness Garage Sleep Checklist to assess your Sleep Hygiene and screen yourself for Sleep Apnea.  Using a sleep tracker in this context can be very helpful to understand what actions you are taking that help or hinder your ability to sleep.
Finally, work with a Lifestyle Medicine physician or health coach to improve your sleep habits while addressing other practices that can improve sleep - especially exercise and stress tolerance. When you have tried everything to improve your sleep, but you are still not sleeping, it is time to dig deeper and determine if there is something else going on. By far, the most common sleep disorder is obstructive sleep apnea. It is estimated that up to 30% of Canadians suffer from it, yet only 6.4% have recognized the diagnosis.  What is Obstructive Sleep Apnea? Sleep apnea is a serious condition in which a person’s breathing is repeatedly interrupted during the night. During normal sleep, air moves in an unobstructed, regular rhythm through the upper airway, the throat into and out of the lungs. With obstructive sleep apnea (OSA), airway blockages, usually from soft tissue collapse, prevent the normal regular breathing rhythm. What are the symptoms? The main symptoms of OSA are
However, some people have no symptoms or may not recognize that they have symptoms. Other symptoms may include one or more of the following:
The key to addressing sleep apnea is to recognize it - start with our downloadable checklist - if you score as high risk, talk to your doctor about getting a sleep assessment. (For more on Sleep Apnea - check out our previous post: Sleep Apnea - what you need to know). Other significant sleep disorders will get picked up through this review process. Excessive daytime sleepiness due to narcolepsy or other central types of hypersomnolence will be considered before or after sleep apnea is ruled out, depending on your history. Sleep-walking or excessive movements in bed, restless leg syndrome or other disorders are best managed with a referral to a sleep specialist. The Wellness Garage SLEEPSounder approach leverages a check-list system. Start by assessing your current sleep habits - we refer to this as sleep hygiene. In all cases, improving these will be part of the solution for your concerns. At the same time, screen yourself for obstructive sleep apnea - if you score anything other than Low - bring the checklist to your physician to review. They will determine the next steps - either a referral for a Home Sleep Apnea Test or a consultation with a sleep specialist. This was part 3 of our SLEEPSounder series, the other posts:
 Getting a good night’s sleep is a challenge faced by many. Lack of sleep has become an epidemic in our society and is increasingly common as we age. There are many causes for poor sleep, some of which need medical assessment, but mostly our ability to sleep well is within our control. Here is a safe and proven framework for sleep. If you are not sleeping well after implementing this, a visit with your physician is warranted. A good night’s sleep is all about optimizing your behaviours and environment to fit your body’s natural rhythm. As humans, we have evolved to be awake when it is light and to sleep when dark. Supporting this circadian rhythm is a cascade of different hormones that signal the body to be alert or sleepy. Our days start with a morning burst of our ‘get up and go’ hormone cortisol, signalling that it is time to greet the day. Over the course of the day, our cortisol wanes until in the evening levels are close to zero. In parallel, adenosine levels build up, signalling fatigue. Adenosine is a by-product of energy expenditure – the more active we are, the greater our adenosine levels. Finally, when dark, our brains release melatonin signalling it is time to sleep. (read more about the Importance of Sleep)  Aligning our behaviours to our body’s hormonal symphony is relatively straight-forward: First, avoid substances that will alter hormones and affect your sleep:

Linked to the 24-hour light-dark cycle, humans wake at first light and go to sleep when dark. Along with sleep, much of our physiology is dependent on this circadian rhythm. 30-40% of our genes are either turned on or off by the presence or absence of light. So we have evolved to eat and be active during the day and to rest and digest at nighttime. But what exactly does sleep do? Increasing evidence points to the importance of sleep for brain maintenance. Our brains need downtime to clear the metabolic waste from the activity of thinking. During the day, our brains are highly active, with high metabolic demand. As the day progresses, metabolic waste increases and needs to be cleared for the brain to function optimally. When we sleep, glymphatic channels open in our brains, cerebrospinal fluid circulates, removing the accumulated metabolic waste. While this is happening, our neurons reshape themselves - building new synaptic connections and pruning old ones. Memories are consolidated from short-term storage in our hippocampus to long-term memory in our cortex. We learn new things at night when we sleep, and we forget things that are no longer important (like the number of the hotel room we just checked out of). Through our dreams, we also make new connections between different memories. Without sleep, these memory consolidations do not occur, and learning, memory, and psychological health all suffer. Without sleep, metabolic waste is not cleared, increasing the risk of dementia. Of course, the adverse effects of the lack of sleep go well beyond brain health:
So while we may not fully understand all the effects of sleep, these associations remind us of sleep’s vital nature. Sleep architecture: When we sleep, our brains run through a predictable cycle of sleep stages: Light sleep: Stage 1 - transition from wakefulness to sleep Stage 2 - body temperature drops, heart rate slows, sleep spindles appear Deep sleep Stage 3 - muscles relax, blood pressure decreases, breathing slows Stage 4 - deepest sleep REM - (Rapid Eye Movement Sleep) - dreaming Each cycle takes approximately 90 minutes to complete. In the first part of the night, we get more deep sleep; in the second part, more REM. This pattern is likely related to the consolidation of memory in the first part of the night and new insights and creative connections in the second half. Even from this brief review, you can see the peril in cutting short your sleep. Losing 90 minutes of sleep may cut out a complete sleep cycle and, with it, the loss of learning and creativity. To understand how we can optimize our sleep, we need to know how sleep comes about. Sleep and arousal are closely tied to the light-dark cycle. In the early morning, just before dawn, our brains send signals to our adrenal glands to release cortisol. Cortisol, often referred to as our “stress hormone,” is really our “get up and go” hormone. It mobilizes energy and activates our brains and bodies to be alert for the day ahead. As the day runs its course, cortisol levels decrease until they are barely detectable in the evening before bedtime. As we are active, metabolites of brain activity accumulate, most notably adenosine. The subjective feeling of fatigue correlates closely with adenosine levels. In fact, caffeine blocks adenosine receptors and makes us feel more energetic by blocking the fatigue signal. The gap between the increasing levels of adenosine and the decreasing cortisol concentration has been referred to as sleep pressure. Throughout the evening, this sleep pressure builds until darkness hits and the pineal gland in the brain release melatonin, triggering sleep.  How this sleep symphony of hormones plays out determines whether you have a good night of sleep or whether you lie in bed sleepless.
Aligning your behaviours with your sleep hormones is the best way to ensure that you get a good night’s sleep and all the benefits that accrue from it.  The final post in the LEVELUp Your Fitness Strategy.
You now have learned the LEVELUp Your Fitness Strategy. How do I implement this? The first thing is to identify where you are starting from: If you have not been exercising regularly over the past month then start with steps 1 and 2: If you are exercising regularly (LEVEL 1), but not doing resistance training with adequate functional movement then start with steps 3 and 4: 3. Resistance training 4. Functional movement training Finally, if you doing all of this (LEVEL 2) but feeling plateaued in your fitness focus on: 5. Aerobic Progression For each progression, give yourself at least 6 weeks or longer.  Seven keys to success:
 What do I do if I get injured?
If you have pain that limits you from exercising for more than a few days, consult with a physiotherapist. It is much better to jump on injuries early than to wait. Your physio will be able to help you understand what to do to resolve the injury as well as (more importantly) what to do to prevent the injury from recurring. What if I miss a few days? Pick up right where you left off. Listen to your body and go more slowly if necessary. What if I miss a few weeks? Start back at 50-65% of your usual workload and duration. Focus on good form. Pay extra attention to warm-ups and stretching. Can I exercise if I have a medical condition? If you have a medical condition and are concerned about starting an exercise program, consult with your physician. The risks associated with following a well-designed exercise program are very low and the benefits far outweigh the overall risk. Need help?

Our exercise physiologist will assess what you are currently doing and provide you with a personalized fitness plan based on the LEVEL Up Your Fitness Strategy. Your aerobic fitness progression eventually will take you to specific training types that develop the muscles’ energy systems. All force generated by muscle requires energy. All energy-requiring processes in the body use the energy stored in a molecule called adenosine triphosphate (ATP). ATP works like a battery storing a small amount of energy for future use. The metabolism of glucose and fat generates ATP, and muscles use ATP to generate the force that powers our activities. The more efficient you are at delivering ATP to muscles, the fitter you will become.  Photo by Tikkho Maciel on Unsplash Your muscles use three energy systems during exercise to provide ATP to generate the force required to meet the demands of your chosen activity. Although no system works completely independently from each other, one or a combination of two will become dominant depending on the exercise’s duration and intensity. Energy Systems 1) The Immediate System Muscles store a small amount of ATP that can be used immediately for a couple of seconds. Along with ATP, muscles also store something called phosphocreatine, which can rapidly generate ATP. This combination of ATP and phosphocreatine is known as the ‘immediate system.’ It is the dominant energy source during short durations (up to around 10-12 seconds) along with high-intensity efforts. Activities requiring short bursts of high energy: weight training, sprinting, and shot-put utilize the ‘immediate system.’ The availability of stored ATP and phosphocreatine becomes the limitation of the ‘immediate system.’ 2) The Glycolytic System For activities requiring high intensity for 30 seconds to 2 minutes, muscles use glycolysis, which rapidly converts glucose to lactate and does not require oxygen. After two minutes, the build-up of lactic acid becomes too high, and the muscles get that dreaded burning sensation and performance drops. Activities like hockey, CrossFit, and middle distance running and swimming (i.e. 800m run, 200m swim) predominantly leverage the anaerobic lactic system. The accumulation of lactic acid, rather than a fuel shortage (glycogen = stored glucose), limits this energy system. 3) The Aerobic Energy System Lower intensity activities utilize the slower aerobic system where glucose and fat combined with oxygen generate large amounts of ATP through oxidative phosphorylation in the mitochondria. Aerobic activity can be maintained for extended periods (hours). Activities like walking, jogging, running, hiking, cycling, biking, and swimming are predominantly aerobic. In the aerobic zone, your body will preferentially use fat for fuel, requiring oxygen to generate energy through oxidative phosphorylation. Your breathing will be more rapid than at rest, but you will not be gasping for air. Your heart rate will be less than 65% of your maximum heart rate. Above 65%, your body begins to recruit glucose (from stored glycogen) for energy. The aerobic system has no energy limitation as long as it is using fat. As you go faster, at intensities above 65% of maximal heart rate, your muscles will begin to use glucose from stored glycogen. Glycogen along will muscle fatigue are the ultimate limiting factors for the aerobic system. When you start exercising, we recommend that you spend most of your time in the aerobic zone. As your pace quickens and you have mobilized glucose from glycogen, glycolysis may not keep up with the slower, aerobic, oxidative phosphorylation and lactate levels will begin to build. The Aerobic Threshold is the point at which your energy is no longer provided exclusively from the aerobic energy system. Training at a pace slightly slower than your aerobic threshold is ideal for developing your aerobic system. (Zone 2 training.) As you develop the aerobic system, your pace will increase at the same intensity and heart rate, allowing you to go faster for longer before activating glycogen use (stored glucose). For long-distance athletes, the more efficient their aerobic system, the faster they will go at higher intensities. Even athletes in sports that do not predominantly use the aerobic system, like hockey or Cross-Fit, will find that improve aerobic endurance will increase their performance and improve their recovery. After you cross the aerobic threshold, lactate levels gradually increase until a point at which your ability to recycle lactate becomes overwhelmed, and lactate levels rise exponentially - this is the anaerobic threshold. At this point, you are no longer able to sustain a given workload, and fatigue sets in, which will limit your endurance ability. The anaerobic threshold is often a good predictor of endurance sports performance because athletes with higher thresholds can race faster for longer and at a higher percentage of their VO2max. You can train the lactic system, exercising at paces close to the anaerobic threshold. Training to Increase VO2max VO2max refers to the maximum volume of oxygen that your body can consume during exercise. Maximal oxygen uptake occurs at very high intensities of exercise. VO2max is a good measure of aerobic fitness. Workouts designed to improve VO2max are typically very high in intensity and only last up to a few minutes at a time. ZONE TRAINING Training zones are a way of quantifying specific intensities during your training. Heart rate or perceived effort can be great ways to determine your training zones; however, more specialized aerobic performance testing can allow you to determine the exact intensities for each zone. Each zone has a different training purpose.  Zone 1 (Recovery Zone)
Zone 2 (Aerobic Zone)
Zone 3 (Junk Zone)
Zone 4 (Lactic Training Zone)
Zone 5 (VO2max Training)
For individuals looking to monitor intensity with heart rate training, identifying your maximum heart rate can be a great starting point. Here is an easy formula to estimate your maximum heart rate: Max Heart Rate = 220 - your age (For example, if you are 30 years old, your maximum heart rate would be close to 190 beats per minute (bpm) (220-30=190)).  Progressing your aerobic capacity will require thoughtful combinations of workouts with different intensities. This type of training is best done with an experienced coach or exercise professional.
Need help with aerobic progression? Get a personalized fitness plan to help you get started, progress or improve your enjoyment of physical activity The TARGET Fitness Plan gives you expert advice to transform your exercise habits - whether you are getting started or want to improve your current program. Our exercise physiologist will assess what you are currently doing and provide you with a personalized fitness plan based on the LEVEL Up Your Fitness Strategy. So far in the LEVELUp Your Fitness Strategy, we have encouraged you to move, get 150 minutes of moderate to vigorous exercise, add some resistance training and functional movement to your routine. At this point, you are getting most of the benefits of exercise, and you are getting fit. Our next goal is to help you progress your aerobic fitness. Aerobic training or cardiovascular training (cardio) enhances muscular and cardiovascular endurance - you can do more for longer and recover more quickly. In other words, you have better energy to enjoy your life.  Aerobic fitness also allows you to:
Our starting point for aerobic fitness is 150 minutes of moderate to vigorous activity maintained for 6-8 weeks. After this initial base, you are ready to think a bit more about aerobic or cardio workouts, starting with steady-state training. Steady-state workouts involve your major muscle groups (arms and legs) in continuous, rhythmic action. Walking, jogging, running, biking, swimming, hiking, rowing, using the elliptical or stair-climber - all lend themselves to steady-state cardio. The most important thing is to find something you enjoy! Start Low and Go Slow Your initial pace should be easy to moderate. You should be able to hold a conversation, though your sentences might be a bit clipped. Most importantly, you should feel fresh enough at the end that you could go longer. When you start or come back after some time off, this will feel really slow. Don’t worry; when you are consistent with your training, you will get faster at the same effort within weeks. The biggest mistake made at this point is to go too fast and get injured. Your endurance, fitness and benefits all build as you progress your steady-state cardio in duration, frequency and eventually intensity. The first progression we recommend is duration and frequency. When you start, you will likely be doing three 20-30 minute aerobic workouts in addition to your resistance training and functional movement. You will find that increasing the frequency of workouts and duration will go together. An important rule of thumb is to add no more than 10% volume to your load each week as you progress. For example, if you are jogging 20 minutes, three times a week, for a total of 60 minutes - 10% is only 6 minutes - that you will add to a single workout. As the volume builds, you will find it easier to add an additional workout. This initial phase of aerobic progression is often called ‘building the base.’ After several months, you will have the base necessary to progress to higher intensity workouts. Don’t rush this phase - at first, it will seem slow, but trust us, as you get fitter, you will get faster at the same intensity.  Photo by Martin Magnemyr on Unsplash Building to Higher Intensities Once you have a solid base of aerobic fitness, you can progress from easy to moderate paces to faster, more vigorous intensities. Training at higher intensities is an excellent way to improve your aerobic fitness but does have some potential drawbacks:
Higher intensity cardio is incredibly challenging and fatiguing for less fit individuals, hence the reason to take your time to build a solid base. The key to minimizing these risks is to plan carefully and listen to your body (or work with an exercise professional). Start with a single workout per week at a higher intensity. There are many different types of higher intensity workouts that you can add. Tempo Pace The simplest way to go is to increase the steady-state workout’s intensity to something called ‘Tempo Pace.’ Start with 5 minutes at your moderate conversational pace before accelerating to a speed that you cannot hold a conversation. Hold the faster pace for 20 minutes, then recover by finishing with 5 minutes at a slow and easy pace. HIIT (High-Intensity Interval Training) HIIT incorporates periods of intense, short-duration exercise with periods of recovery. These periods are referred to as the “work” interval and the “rest” interval. Work intervals are typically 3-5 minutes, although sometimes as short as 30 seconds, and they are performed at a vigorous intensity (6-8/10 effort). Rest intervals are often equal in duration to the work interval with a 1:1 ratio; however, shorter work intervals under 3 minutes typically require a 2-3 minute recovery. Usually, about 3-6 sets are performed. These intervals are best done with coaching and guidance as they are challenging to plan for as a beginner. Hill Workouts Using nature’s resistance, you can do interval training by doing intervals on hills. For example, you could do eight times a short, steep hill or four times a long, gradual hill. The key to hill training is to be sure that you can keep good form as you jog, run or bike up the hill. Fartlek Training The Swedish work “Fartlek” means “Speed Play” and is a type of workout that allows for moderate AND vigorous training. Typically easy pace training is performed for most of the workout with brief high-intensity intervals scattered throughout. It can be performed in a structured or freestyle manner and is a great way to improve both the aerobic (low intensity) and lactic (high intensity) energy systems. Fartlek training is also a great way to keep workouts fun, and is often used in running, cycling, and swimming. An example of Fartlek Training is going for an easy jog but then sprinting up each hill you come across. Besides increasing your steady-state cardio intensity, you can add high-intensity training to your week by combining these workouts with your resistance training. Circuit Training Resistance training can be a great way to push the aerobic system as well. Performing various rounds of exercise combinations at vigorous efforts can be an efficient way to hit strength and cardio in the same session. Circuit Training is sometimes referred to as HIIT training as well, as periods of recovery may be incorporated, or intervals of different exercises are performed. Here are some of the many examples of circuit training: Superset Training Superset training involves performing two exercises back and forth rather than resting after 1 exercise. For example: Perform the bench press for ten reps, then instead of resting performing the bent-over row for ten reps. Repeat for the desired number of sets and rest as needed. Classic Circuit Training Classic circuit training involves performing various exercises (typically 3-4) without rest in a round. For example, bench press for ten reps, bent-over row for ten reps, squats for ten reps, repeat and rest as needed. Tabata Choose an exercise that you will work with for a total of 4 minutes in duration. Perform the exercise for 20 seconds, get as many good-quality reps as possible, and rest for 10 seconds. Repeat this for eight sets (4 minutes). EMOM (Every Minute On the Minute) Perform the given exercise for the prescribed number of reps for a minute. If you finish early, rest for the rest of the minute. If you don’t finish, move on. Start the next set over again once the new minute starts. Other exercises can be integrated into an EMOM workout. SAMPLE EMOM: 6 minutes of 10 burpees and a 45-second plank Minute 1: 10 burpees Minute 2: 45-second plank Minute 3: 10 burpees Minute 4: 45-second plank Minute 5: 10 burpees Minute 6: 45-second plank Be sure to follow every high-intensity training day with an easy day - steady-state cardio or functional movement. Never do two hard workouts back to back on consecutive days. For most non-athletes, regular folks, two hard workouts per week is enough. Listen to your body and progress slowly to avoid injury and burnout; if you are fatigued on your hard-workout day, just perform a lighter one. Burning Fat? Performing aerobic exercise causes your body to break down either glucose, fats, or both for energy. Since glucose is broken down rapidly, higher-intensity efforts rely mostly on glucose over fats rather than lower-intensity efforts, which typically rely on a combination of the two. Teaching the body to rely on fats Base training or light training (especially in a fasted state) can help the body learn to rely on fat oxidation: the breakdown of fatty acids for energy. This is done by training at lower (moderate) intensities at a steady pace. Providing glucose by eating carbohydrates pre-workout will force the body to use the glucose for fuel since it is the most available energy source. Because of this, fasting before this type of training is encouraged. If fasting is not possible, make sure not to eat too many carbohydrates immediately before or during exercise. Relying on fats for energy is excellent for sparing muscle glycogen (stored glucose). This can, in turn, help to prevent hunger cravings post-workout and allow an individual to exercise for long periods. For long-distance endurance athletes, training to improve fat utilization is essential to not run out of glycogen at the end of their race. Running out of glycogen causes a steep drop in energy - a truly awful feeling known as “hitting the wall.”  Need help starting resistance training?
