Muscle Size Increases - What's Happening Within Your Muscles
Is bigger always better when it comes to strength training? In this episode, Amy Hudson and Dr. James Fisher break down the science of muscle growth, revealing why increased size doesn’t always equal increased strength. From neural adaptations to muscle fiber recruitment, they explore what’s really happening inside your body when you train – and why understanding it can transform the way you approach your workouts. Amy Hudson and Dr. James Fisher talk about increasing muscle size, and when that doesn’t happen. Back in the 1980s, a hypothesis by Digby Sale looked at the two key adaptations most people are interested in when it comes to growing their muscle. Hypertrophy is an increase in muscle size. Dr. Fisher explains that, “When we begin strength training, almost 99% of our adaptations and increases in strength are neural.” Dr. Fisher goes on to say that at some point our hypertrophic adaptations, or increase in muscle size, will kick in which can lead to an increase of muscle strength as well. Did you know that most people aren’t able to recruit 30% and maybe 90% of their muscle fibres. Dr. Fisher touches upon a project that looked at the different reactions (and results) between people used to exercise and some who typically don’t… “The increase in force and the increase in ability to produce force is a product of our ability to send continued, sustained and higher frequency impulses from our brain to our muscle fibers,” says Dr. Fisher. There are different structures within a muscle: the muscle fascicle, the muscle fiber, and the myofibrils. A 1-2% change in one of them doesn’t equal a change in the whole muscle. Dr. Fisher and Amy go through each muscle structure and its role within strength training and in the muscle growth process. It’s good to note that “myo” refers to muscle, so myofibril, for instance, refers to a fibril within a muscle. Hypertrophy revolves around an increase in size, while hyperplasia has to do with an increase in numbers. There’s some evidence around hyperplasia, though many people still question whether it truly exists. Did you know that somebody that has average size in muscles but is very strong has arguably better muscle quality than somebody who can produce the same amount of force but has much bigger muscles? The conversation touches upon two ways to measure muscle growth, “in vivo” and “in vitro,” as well as muscle architecture, the motivators for wanting to increase the size of one’s muscle, and the pennation angle of our muscles. For Dr. Fisher, strength training is wasted on people that just want bigger muscles, as it’s a superficial acceptance or adaptation to strength training.

Fix Your Core, Fix Your Back: Personal Training Insights You Probably Haven’t Heard Before
Think core training is all about crunches and six-packs? What if the real key to a strong, pain-free core is the muscles you can’t see? Hosts Amy Hudson and Dr. James Fisher dive deep into the science of core strength, bust common myths, and reveal how personal training can help you target the low back and pelvic muscles that truly support your spine, posture, and overall function. Today’s episode features hosts Amy Hudson and Dr. James Fisher addressing a listener’s question about the core. Dr. Fisher starts his contribution by discussing the origin of the core, as well as where it’s located and why its role is crucial. Amy points out that, for many people, “core” is synonymous with abdominals - when, in reality, other muscles, including the back, low back, and pelvic floor, are all part of the core. Wondering whether you have weak muscles in your core? If you’ve experienced some degree of low back pain or low back stiffness, then those may be symptoms of a core that needs to be strengthened… “One of the most common reasons for non-specific mechanical low back pain, which accounts for about 80% of back pain, is simply weak lumbar muscles,” says Dr. Fisher. Furthermore, it’s been shown that strengthening the lumbar muscles can reduce back pain. Dr. Fisher explains why the plank isn’t an exercise that can serve as a good assessment of our trunk - or core - muscles. Having a weaker core and the challenge of training low back muscles link back to the so-called deconditioning hypothesis - Dr. Fisher unpacks this further. Paraphrasing Dr. Fisher, Amy stresses how “It’s not very easy to effectively activate and train and strengthen those muscles in the low back with everyday activities.” Dr. Fisher highlights how low back muscles are predominantly type-1 muscle fiber, so they’re not high-force muscles, but rather high-fatigue resistance muscles. Dr. Fisher and Amy go through some workout routines that can help strengthen low back muscles (especially the ones you don’t see). Working in their laboratories with people with low back pain, Dr. Fisher and his colleagues have seen a 200% strength increase over a 10-week training period. Dr. Fisher and Amy talk about why doing a bunch of sit-ups isn’t the right way to obtain six-pack abdominals. Mentioned in This Episode: The Exercise Coach - Get 2 Free Sessions!

Evidence-Based Strength Training: Ditching Old Paradigms for Proven Success
When it comes to your health and to your strength training, more specifically…Do you rely on social media trends or real science for your exercise routine? And how do you know if your workouts are actually safe and effective? Amy Hudson and Dr. James Fisher break down what “evidence-based strength training” really means, exposing common myths and highlighting why scientific research – and not old paradigms – should drive your fitness decisions. Hosts Amy Hudson and Dr. James Fisher unpack evidence-based strength training. Dr. Fisher believes that personal trainers should embrace an evidence-based approach, for the fact that people see them as part of the healthcare continuum, just like doctors, dentists, etc. Dr. Fisher explains what “evidence-based” actually means and what it entails. Remember: when it comes to strength training, there’s a lot of misinformation on social media platforms. As Amy points out, hearing someone talk about the benefits they got by training a certain way doesn’t automatically translate into you achieving the exact same result with the same workout. There are a variety of factors that could impact that, such as your varying ability levels, the metabolic competencies of your body, where you are with your joints, and more! Dr. Fisher touches upon the ACL reconstruction surgery he had and how that plays into the topic of evidence-based strength training. “Many institutions rely on evidence-based processes and on scientific research to drive their methodology forward. And strength training is no different at all,” says Dr. Fisher. Amy and Dr. Fisher talk about what evidence-based strength training actually looks like. Did you know that about 90% of exercising injuries are a product of free weight strength training? Training alone or having a supervised strength training session? According to some scientific evidence, supervision shows greater benefits in almost all facets of health, well-being, and physical adaptation compared to unsupervised workouts. The historic thinking and old paradigms that exist have been debunked by more recent science. And that’s really what evidence-based training is all about: being able to move with the scientific process. Interacting with coaches and asking them key questions is something Dr. Fisher believes anyone should do. Mentioned in This Episode: The Exercise Coach - Get 2 Free Sessions!

Beyond the Gym: The Role of Protein in Personal and Strength Training Success
Did you know that what’s on your plate can help you while you’re at the gym? Join hosts Amy Hudson and Dr. James Fisher as they dive into the vital role of protein in muscle health and strength training. What’s the ideal protein intake you should aim for every day? And where can you get proteins from, in the first place? Whether you’re just starting out or enhancing your regimen, this episode will equip you with the knowledge to optimize your protein intake for maximum personal training and health gains. Hosts Amy Hudson and Dr. James Fisher begin the conversation by discussing why dietary protein consumption is so important for muscle health. Dr. Fisher explains how dietary habits are more important than your engagement in muscle-building exercise for the fact that, while you may engage in strength training a couple of times a week, you eat every single day. Muscle protein synthesis is the process of muscle regeneration, while muscle protein breakdown is the destruction of muscle protein cells. As we age, we have an elevated muscle protein breakdown compared to our anabolic youth. To combat the natural breakdown, it’s important to ensure we engage in things that will elevate our muscle protein synthesis. Dr. Fisher unpacks the concept of amino acids and touches upon essential and non-essential amino acids. When it comes to diets, Dr. Fisher typically advocates for a whole food, less processed, relatively varied diet. Dr. Fisher brings the topic of animal-based and plant-based proteins into the conversation. Remember: the engagement of strength training is the boost to muscle protein synthesis to try and hang on to every ounce of muscle we’ve got – and proteins are going to help to do that. Dr. Fisher goes into the differences between plant-based sources of proteins, animal-based proteins, and supplemental proteins. When it comes to animal-based proteins, grass-fed or free-range poultry or beef are at the top of the list. For Dr. Fisher, the UK Government's recommendation of 0.75 grams of protein per kilogram of body weight is way too low. Evidence-based studies by Dr. Stuart Phillips, Brad Schoenfeld, and colleagues show that the amount of protein for muscle protein synthesis is between 1.6 and 2.2 grams per kilogram of body weight per day. As far as meal planning and protein intake are concerned, Dr. Fisher suggests being in the region of 32 to 44 grams of protein per meal. Constantly feeling hungry? It may be that you aren’t consuming enough dietary protein to keep you full for long enough between your meals, says Amy. Amy goes into the “blood sugar rollercoaster”. As we age, our muscle protein breakdown increases – meaning that we have a higher need for protein to combat that with more muscle protein synthesis. Dr. Fisher and Amy share some final considerations about the role of protein, especially for those who haven’t paid much attention to their dietary habits or who have just started engaging in strength training.

Beating the Gym: How Personal Trainers and Supervised Training Lead to Lasting Fitness Habits
Big Box Gyms: Yay or Nay? And how do they compare to working out with a personal trainer? Amy Hudson and Dr. James Fisher look at big box gyms and the benefits of working with a personal trainer. You’ll hear about everything from motivation and habit-building to fitness results, and will walk away with clarity on which option to go for to make the most out of your time and exercising efforts. Dr. James Fisher kicks things off by sharing a frightening stat: only about 10% of the population engages in regular strength training. What’s interesting is the fact that only about one-third of people attend big box gyms, meaning that about two-thirds of people don’t actually even attend once per week… Dr. Fisher and some of his colleagues have done some research and have identified a lack of motivation, not being supervised and advised by a personal trainer, and not seeing progress from your workouts, as key factors that lead to that phenomenon. Did you know that 50% of new gym members will stop their membership within the first six months because of non-attendance? True, big box gyms provide you with the space and equipment you need… but if you aren’t already engaged or lack a certain level of understanding and commitment, you won’t attend regularly. To some degree, gyms are reliant upon a degree of non-attendance – if all of their members showed up at the same time, they would have to turn some people away because of maximum occupancy. Dr. Fisher touches upon a couple of big social elements that play a crucial role in the big box gym context. Ask yourself this: “When thinking about the gym, do I go there for the health benefits of exercising or for the social element in that environment?” Amy Hudson talks about the lack of time aspect that’s often part of the equation for many people who are thinking about strength training. Dr. Fisher and Amy discuss how a model like the Exercise Coach Studio’s one differs from big box gyms and helps people succeed. Studies on exercising motivation show that, unlike other groups like people who focus on CrossFit, people engaged in supervised strength training reported higher motivation for things such as ill health avoidance and health-related benefits as key reasons for exercising. Amy lists one of the key motivators for having a personal trainer: it collapses the timeline for you to get where you want to get to. As she points out, getting people to that place of seeing results faster will lead to them being motivated and wanting to continue with exercising regularly. Amy shares a question they often ask their Exercise Coach: “If you and I were sitting here a year from today, what things would have to happen for you to feel very satisfied with your progress?” Amy and Dr. Fisher go into studies in which participants were paid to go to the gym… but were still unsuccessful with exercising regularly. A good reminder from Amy: motivation is hard to keep, and it’s important to stay honest about that. 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.

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.

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.

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!
