  • Personal Training for Aerobic Fitness: The Science Behind VO₂ Max and Cardio Gains
    What does aerobic fitness really mean — and how can personal training help you improve it?? Amy Hudson and Dr. James Fisher break down VO₂ max, heart rate, and the science behind combining strength training with interval workouts. From boosting cardiovascular health to reducing fatigue and disease risk, they explain how targeted personal training can transform your conditioning and overall well-being. Amy Hudson and Dr. James Fisher look at the benefits of having increased aerobic capacity, how to increase it and the role of both strength training and brief interval training in aerobic capacity. One of the most common terms used in scientific literature is VO₂ max which represents the maximum volume of oxygen our body can take up and use. Dr. Fisher explains that whenever we talk about cardiovascular fitness or cardiorespiratory fitness, it’s about how well oxygen can move around our body. Dr. Fisher and Amy talk about why VO₂ max and CO2 (carbon dioxide) are important in terms of their fitness. Did you know that your conditioning level, to some extent, can determine what exercise level or exercise intensity you can work at to maintain working aerobically? Not only daily fatigue but also your sleep, risk of depression and anxiety, risk of coronary artery disease and hypertension, and the risk of diabetes are all positively impacted by an improved aerobic conditioning. Dr. Fisher approaches the audience question: Does knowing one’s resting heart rate indicate anything to that person about their current state of cardiovascular health or aerobic capacity? As you improve your fitness, you improve what’s called cardiac output and stroke volume. If you’re curious about your maximum heart rate, you can calculate it by taking the number 220 and deducting your age from it… Amy brings interval training and glycogen into the conversation. Dr. Fisher explains that the importance of having a strength training workout and then doing concentrated cardio at the end is actually great because it serves as this glycogen dump. Dr. Fisher goes into EPOC – Excess-Post Exercise Oxygen Consumption – and the specificity of an action and, specifically, a sport itself.     Mentioned in This Episode: The Exercise Coach - Get 2 Free Sessions!

  • Forget More Reps – Here’s What Makes a Workout Effective
    What’s the secret to an effective workout? More reps? More sweat? More weights? In this episode, Dr. James Fisher and Amy Hudson break down the science behind strength training, revealing why muscle fatigue, not time or reps, is the real key to results. From type-2 muscle fiber recruitment to recovery strategies, what you’ll hear will help you rethink how you train and why less might actually be more. Dr. Fisher and Amy address the “million-dollar question:” What’s the secret to effective exercise? Dr. James Fisher is a fan of questions such as What is the stimulus? – He likes that once we have in mind that the exercise is the stimulus to adaptation, we can just stop blindly going and doing as much as we can. Dr. Fisher and Amy Hudson share the secret of effective exercise: fatiguing the muscle or working it at the right level of intensity. Dr. Fisher touches upon type-1 and type-2 muscle fibers – and why you should want your workouts to recruit type-2 muscle fibers… Amy and Dr. Fisher list a few signs that you may have recruited your type-2 muscle fibers the right way. Dr. Fisher cites some of his research on dissociating effort from discomfort and some interesting findings related to it. Some studies have shown that people who are averaging 6-10 hours of sleep per night will build strength in muscle size quicker than those sleeping an average of less than 6 hours. Remember: the workout is the stimulus; it’s the time after the workout that allows that muscle adaptation. “All the wonderful benefits that strength training delivers happen during those recovery days between your sessions,” says Amy.   Mentioned in This Episode: The Exercise Coach - Get 2 Free Sessions!

  • The Way to Use 20 Minutes to Real Fitness Results
    Can just 20 minutes with a personal trainer really make a difference? In this episode, Amy Hudson and Dr. James Fisher explain why effort – not time – is the true driver of fitness results. From the science of stimulus to the dangers of overtraining, they reveal how shorter, smarter workouts can transform your body and redefine your approach to exercising. Amy Hudson and Dr. James Fisher discuss whether the amount of time you spend exercising is indicative of what results you should expect. Amy kicks things off by introducing the 2x 20-minute approach the Exercise Coach’s personal trainers advise their client to embrace. Some clients ask whether they should exercise more to accomplish their fitness goals... Dr. Fisher touches upon the inefficiency or lack of quality that’s almost always tied to working or exercising for long periods of time. According to Dr. Fisher, what we need to think about in terms of exercise is stimulus. Exercise is the stimulus to adaptation, it’s not the adaptation in and of itself.  The goal is for exercising to provide the stimulus to our body to improve our cardiorespiratory fitness, our ability to deal with blood lactate accumulation, to recruit muscle fibers, get stronger, and increase muscle size and our metabolism. Dr. Fisher and Amy talk about the danger of overtraining and what that may lead to. A 20-minute session with a personal trainer can do wonders when it comes to your fitness goals – Dr. Fisher and Amy explore why that’s the case. Remember: the key is not how often and for how long your train but it’s effort level you’re working at. “What we encourage our clients to do is, basically, to become more in tune with their own body to understand the sensation that the stimulus of a full effort of an exercise session gives your body, and to understand how long your recovery will take,” says Amy. Amy has noticed how eye-opening it is to her personal training clients to get to know their own body, see and feel it respond to the stimulus that we’re creating, and watch it change. Dr. Fisher and Amy discuss the importance of following a sustainable workout. Dr. Fisher and Amy point out the difference – and common mistakes – between a workout at a regular gym and a session with an Exercise Coach personal trainer.   Mentioned in This Episode: The Exercise Coach - Get 2 Free Sessions!

  • Fitness Isn’t Just Steps: Why Effort Matters More Than Your Step Count
    Are your daily steps really telling you how fit you are? Amy Hudson and Dr. James Fisher unpack the limitations of step tracking and explain why effort, not volume, is the true driver of fitness. From sedentary habits to the power of strength training, they reveal what actually moves the needle when it comes to improving your health and longevity. In today’s episode, Amy Hudson and Dr. James Fisher look at whether there’s a meaning behind taking and tracking a certain number of steps and its role within the fitness context. While tracking our steps can make us feel good about ourselves and being active, it’s something that doesn’t tell us the full story about our fitness. Tracking steps is founded on a good evidence base: a study showed that taking between 7,000 to 10,000 steps per day is associated with a lower risk of mortality in older adults.  Dr. Fisher talks about a recent Exercise Coach Franchise Conference and the importance he gives to tracking how much time he spends in a seated position. Going for a jog and a walk when attending a conference helps Dr. Fisher get some exercise done during the day and get some daylight… Dr. Fisher believes that tracking the number of steps taken during the day is particularly important for those with a sedentary job or inactive lifestyle. Knowing how little steps one takes during the day can prompt lifestyle changes.  The main problem with tracking steps is that we start to become quite volume-monitored, rather than effort-monitored. Dr. Fisher points out that, nowadays, people should aim for 12,000 steps instead of 10,000, and that “not all steps are equal.” Think of the difference – in level of effort – between a walk that’s more like a hike and one that’s on completely flat ground, where the heart rate stays low. The risk associated with tracking steps is that it doesn’t give you a good gauge of your fitness, nor of the exercise that you should be undertaking to try and maintain muscle mass and muscle fibers. Don’t focus on the number of steps… focus on effort level. 5,000 steps done as a jog are more effective than 10,000 steps done as a walk. Amy and Dr. Fisher discuss why strength training is the key way to stimulate our muscles, our metabolism, and myokines.  Dr. Fisher sees strength training as the biggest thing that’s going to shift the needle of your overall health and well-being. For Amy, if your goal is to change your body, to add strength, improve bone density, and your hormonal and metabolic health, you have to participate in strength training. Amy gives a definition of exercise: “a stimulus that causes your body to produce positive adaptations.”  Dr. Fisher concludes by sharing a couple of concerns and considerations related to tracking steps.   Mentioned in This Episode: The Exercise Coach - Get 2 Free Sessions!

  • Why Heart Rate Isn’t the Best Measure of a Good Workout
    Think your heart rate tells the whole story of your workout? Think again. In this episode, Amy Hudson and Dr. James Fisher unpack the myths around heart rate tracking, explaining why it's not the best measure of workout effectiveness — and what you should focus on instead. From hunger hormones to interval training tips, you'll walk away with a smarter approach to training that actually supports your fitness goals. Amy Hudson and Dr. James Fisher look at heart rate, what it actually means and whether it’s meaningful or not when it comes to the effectiveness of your workout. With heart rates, we’re looking at how we can move oxygen around the body – all the way where the oxygen is transferred into muscle cells and our active muscle. Dr. Fisher explains that as soon as we move into the higher end of our heart rate, we’re in the carbohydrate burning zone. When we do strength or interval training, our ghrelin – the hormone responsible for the feeling of hunger – doesn’t go up, so we don’t have a hunger response. When we do moderate or low-intensity steady state exercise – and we stay below a certain heart rate zone, we get a spike of the ghrelin hormone. Remember: your heart rate is NOT indicative of the quality of your workout. Dr. Fisher touches upon EPOC (Excess Post-Exercise Oxygen) and explains what it is and when it may occur. Amy and Dr. Fisher discuss interval training and why it’s something you should consider doing if you’ve ever got the chance. Something to be cautious about with interval training: If we’re doing it based on heart rate, it typically takes our body a certain amount of time for the heart rate to respond. This means that the interval has to be long enough to be effective. Next, Dr. Fisher and Amy unpack the concept of resting heart rate and what it means for you in relation to your training. As you may be busy looking into your heart rate, just remember that it gets influenced by external factors such as caffeine, stress, dehydration, illness, and lack of sleep. A good reminder by Dr. Fisher: When we first start tracking anything, we’ve got to remember that it’s just a snapshot. If data is your thing, it's important that you recognize that once you have long-term data, you can start to see trends. Dr. Fisher’s take is to “look at heart rate after the fact (e.g. the workout), not looking at it during the event.” When you’re thinking about your workouts wondering whether they’re working, Amy suggests asking yourself WHY are you exercising? Think about what your goals are with exercising and whether those are happening.   Mentioned in This Episode: The Exercise Coach - Get 2 Free Sessions!
