    How to Keep Your Strength, Power and Endurance as You Age with Professor Peter Reaburn

    Training hard may have built your fitness. But should you keep training the same way as you age? In this episode of Stronger With Time, Tony speaks with Dr Peter Reaburn, a researcher, author and lifelong masters athlete who has spent decades studying performance and ageing. Peter is a retired Professor and former Head of Exercise and Sport Science at Bond University. He has authored and edited multiple books on masters athletes, published peer-reviewed research on masters athletes, and continues to work closely with the masters sporting community. He also practises what he teaches. Peter was the Australian Ironman Triathlon Champion in the 50–54 age group in 2005 and is the current Australian Masters Swimming Champion in the 70–74 years 400m individual medley. At 71, Peter brings both the research and lived experience to the question of how to keep training for strength, power and endurance as recovery and physical capacities begin to change. In this episode: Which aspects of fitness decline fastest with age Why older endurance athletes still need resistance and sprint training The role of fast-twitch muscle fibres in later-life performance How to balance hard sessions with lower-intensity work The hard-easy principle and the 80/20 approach Atrial fibrillation risk in lifelong endurance athletes Protein and recovery needs as we age Menopause and the research gap in female masters athletes When to replace a planned hard session with active recovery The physical, cognitive, psychological and social sides of successful ageing This conversation is for coaches, masters athletes and active adults who still care about performance, but recognise that training harder is not always the same as training better.

    Zone 2, HRV and Concurrent Training: How Elite Endurance Science Applies to Everyday Training — Dr Dan Plews

    🌐 Visit → tonyboutagy.com 📲 Follow us on Instagram → @tonyboutagy The principles that drive adaptation in the world's best endurance athletes are the same principles that drive adaptation in people who train seriously but are not competing. The application changes. The fundamentals do not. Dr Dan Plews is an applied sports scientist, coach and world-class endurance athlete. He holds a doctorate in applied heart rate variability from Auckland University of Technology, has coached athletes to more than 30 world and Olympic titles, and has set records at both the Ironman World Championship and in HYROX. In this episode, we discuss: Why the gap between elite endurance science and everyday training is smaller than most people think. The framework Dr Plews uses with Olympic athletes, identifying the gap between current capacity and the target and then designing training to close it, applies equally to someone training six hours a week for health and longevity. Whether the concurrent training interference effect actually matters for non-athletes. Dr Plews explains that while the interference effect is real, it primarily matters at the highest levels of performance. For most people training six or fewer hours a week, getting the work done in a recovered state matters more than the sequencing of strength and endurance sessions. What zone two training actually is and where the common misconceptions come from. Zone two is defined by physiological markers, not by feel or a percentage of maximum heart rate, and most people who think they are training in zone two are working considerably harder than the research supports. How heart rate variability reflects the state of the autonomic nervous system and why it is one of the most useful tools available for managing training load and recovery. Dr Plews explains how to interpret HRV trends over time, what a suppressed morning reading actually tells you, and how to use it to make better daily training decisions. How low carbohydrate approaches and fueling strategies affect endurance adaptation, why metabolic flexibility matters for both performance and long-term health, and what the evidence shows about carbohydrate availability during training and competition. Why Dr Plews shifted his focus from long-course triathlon to HYROX, and what that shift reflects about building a broader fitness base for longevity rather than optimising for a single performance output. Key insight: Elite endurance athletes succeed by applying the right stimulus at the right time and recovering properly between sessions. That principle does not change when you have six hours a week instead of thirty. The gap between what the best coaches in the world know and what everyday people apply is smaller than it looks, and this episode closes it. Topics: zone two training, concurrent training, interference effect, heart rate variability, HRV, endurance training, polarised training, low carbohydrate training, metabolic flexibility, fueling for endurance, HYROX, triathlon, longevity and exercise, training load management, strength and endurance, applied sports science

    Female Athlete Health, RED-S and the Research Gap in Women’s Sport with Dr Kate Ackerman

    Female athlete health is often discussed in extremes: either physiology is underplayed, or every difference gets turned into a rule. This conversation sits in the middle, where evidence, clinical context and nuance matter. In this episode of Stronger With Time, Tony speaks with Dr Kathryn “Kate” Ackerman, a former elite rower, sports medicine physician, endocrinologist and leading researcher in female athlete health. Kate’s work sits at the intersection of sport, medicine, endocrinology and performance. She explains how her own experience as an athlete shaped her career, why the data gap in female athletes still matters, and how better research can improve both health and performance. Tony and Kate discuss RED-S, low energy availability, menstrual dysfunction, bone stress injuries, fueling, carbohydrate availability, hormone therapy, menopause, and how to think about female athlete health without turning every difference into a rule. They also explore the nuance often missing from online discussions: not every calorie deficit is RED-S, not every female athlete needs a bespoke training plan based on physiology alone, and the goal is not to create fear, but to understand what the evidence can and cannot tell us. In this episode, they cover: The evolution from the Female Athlete Triad to RED-S What low energy availability means, and when it becomes a problem Why RED-S requires clinical nuance, not just symptom counting Screening tools, clinical markers and medical context Bone stress injuries, DEXA, HR-pQCT and delayed bone recovery Transdermal estrogen, oral contraceptives and bone health in amenorrheic athletes Adolescent athletes, loading, fueling, calcium, vitamin D and stress injury risk Carbohydrate availability, meal timing and recovery Menopause, HRT and the gaps still left in women’s health research Why female physiology matters, without turning everything into a sex-specific rule This conversation is for coaches, clinicians, female athletes, parents of young athletes, and active women who want a clearer, evidence-informed understanding of female athlete health.

    Hypertrophy Advice: What to Trust and What to Question with Dr Gerard McMahon

    If you train for hypertrophy, you are probably not short on advice. The harder part is knowing which advice is worth trusting. In this episode of Stronger With Time, Tony speaks with Dr Gerard McMahon, a muscle physiology and biomechanics researcher and applied practitioner who has worked with elite athletes across Olympic, Para Games and Commonwealth Games environments. Gerard brings together research and applied practice: what drives muscle growth, and what that means when you are programming for real people over months and years. Together, Tony and Gerard work through some of the most common claims in hypertrophy training, from mechanical tension and effective reps to volume, activation drills, lengthened partials, periodisation and tendon training. In this episode, they discuss: Why research and real-world coaching both matter What actually triggers muscle hypertrophy Mechanical tension, muscle damage and metabolic stress Why “effective reps” and “stimulating reps” are often misunderstood How training volume should change with training status Why more sets in one session are not always better What muscle activation drills can and cannot do Lengthened partials, lengthened range and where they may be useful Why lengthened training does not apply equally to every muscle Social media echo chambers in hypertrophy advice Drop sets, supersets and high-fatigue methods Periodisation and long-term programming for muscle and strength This conversation is for coaches, personal trainers and experienced lifters who want to think more clearly about hypertrophy training and build programs from principles rather than trends. Timestamps 00:00 Introduction and the social media problem in hypertrophy advice 00:55 Dr Gerard McMahon’s background in sport science, research and elite sport 04:00 Research, coaching and how to judge training advice 06:00 Short-term hypertrophy studies versus long-term programming 08:35 Training volume claims and real-world constraints 10:10 What actually triggers muscle hypertrophy? 13:40 Mechanical tension, load and training to failure 15:30 Proximity to failure and motor unit recruitment 17:20 Effective reps and stimulating reps 21:20 Training volume and training status 23:40 Beginner versus advanced weekly volume 25:10 Signs you may be doing too much volume 26:40 Frequency and dividing weekly training volume 29:40 Muscle activation drills and warm-ups 33:30 Glute activation drills and warm-up specificity 35:20 Habitual movement patterns and activation drills 37:45 Lengthened partials and lengthened range 40:30 Which muscles benefit from lengthened range? 44:30 Quads, hamstrings, calves and lengthened work 47:45 Glutes and the best range for hip thrusts 48:45 Social media echo chambers in hypertrophy 51:00 Neuromechanical matching and exercise selection 53:30 Drop sets, supersets and overload techniques 56:10 Periodisation for hypertrophy and strength 58:25 How long to stay on a program 59:30 Tendon training, tendon stiffness and high mechanical loading 01:02:45 How to learn more from Dr Gerard McMahon Resources: Dr Gerard McMahon research and publications https://scholar.google.com/scholar?q=%22Gerard+McMahon%22+hypertrophy Dr Gerard McMahon on PubMed https://pubmed.ncbi.nlm.nih.gov/?term=%22Gerard%20McMahon%22%20hypertrophy Lengthened partials and hypertrophy research https://scholar.google.com/scholar?q=lengthened+partials+hypertrophy+McMahon No Strain, No Gain tendon research search https://scholar.google.com/scholar?q=%22No+Strain%2C+No+Gain%22+tendon+McMahon Neuromechanical matching review search https://scholar.google.com/scholar?q=Hudson+Gandevia+Butler+2019+neuromechanical+matching Tony’s website https://tonyboutagy.com/ Tony on Instagram https://www.instagram.com/tonyboutagy/ Subscribe to Stronger With Time for more evidence-informed conversations on training, health and performance.

    Hypertrophy Research in Practice: What Matters for Muscle Growth

    Hypertrophy advice can become confusing fast. Different studies, different coaches, different physiological models and different claims online can point to slightly different answers. Sets, reps, frequency, failure, soreness, exercise selection and periodisation are all debated, often with more certainty than the evidence allows. In this episode of Stronger With Time, Tony brings together close to four hours of conversations with leading hypertrophy researchers and turns them into a practical framework for coaches and serious lifters. Across the series, Tony explored muscle hypertrophy through three lenses: the history of strength and hypertrophy training with Professor William Kraemer, the molecular and mechanistic side of muscle growth with Professor Michael Roberts, and practical programming decisions with Dr Eric Helms. This episode is the synthesis. Tony distills the key takeaways into what current evidence suggests about how muscle grows, which variables deserve the most attention, and how that translates into real-world program design. In this episode, we discuss: The three main worldviews coaches use to program hypertrophy Why outcome-based research can be difficult to apply directly to long-term training What muscle hypertrophy is, including radial and longitudinal growth Why mechanical tension sits at the centre of current hypertrophy thinking Where DOMS, “the burn” and acute hormonal spikes fit in Minimalist vs maximalist approaches to training volume Why no single exercise can train every fibre within a complex muscle group Practical implications for pec, delt and glute exercise selection Training frequency, weekly sets and proximity to failure How to think about drop sets, supersets, rest intervals and rep ranges Periodisation, fatigue management and training at longer muscle lengths Who this is for: Coaches, PTs and S&C coaches programming hypertrophy for clients or athletes Serious lifters who want their training aligned with current evidence, not trends Practitioners who care about long-term strength, muscle and joint health Gym owners who want clear hypertrophy principles their teams can apply consistently About Dr Tony Boutagy: Dr Tony Boutagy is an exercise scientist and strength coach with over 30 years of in-the-trenches experience. He is known for bridging hypertrophy and strength research with real-world programming for athletes, general population clients and serious lifters, with a focus on sustainable strength, hypertrophy and conditioning grounded in solid science.

    How to Program for Hypertrophy: Volume, Frequency & Exercise Selection (with Dr Eric Helms - Part 2)

    Hypertrophy programming comes back to a few practical decisions: how close to failure, how much volume, how often, and how much variety. In this episode, I speak with Dr Eric Helms about how to make those decisions with better judgment, and where popular models claim more than the evidence supports. Dr Helms is a PhD researcher in strength and hypertrophy, a coach of physique and strength athletes, and a high-level natural bodybuilder. In Part 1, we discussed how to think about training advice when coaches, research, and physiology models do not point in the same direction. In this episode, we apply that thinking to programming. Some of what we discuss: How close to failure you actually need to train, and when it matters more or less Why “only the last 5 reps count” doesn’t hold up Why estimating reps in reserve gets harder at higher reps How much volume to use, and how frequency changes that decision Why fatigue matters, but may be overweighted in programming decisions Variety vs variation, and why hypertrophy may not need strength-style periodisation Where drop sets, rest-pause, and myo-reps actually fit, as time-saving tools rather than superior methods Who this is for: Coaches programming hypertrophy for general population or athletes, and experienced lifters trying to make defensible decisions about failure, volume, frequency, and exercise selection without chasing every new trend.

    How To Think About Training Advice (with Dr Eric Helms – Part 1)

    If you coach or train seriously, you have probably had to weigh different sources of training advice against each other. A successful coach recommends one approach. A research paper seems to suggest another. A physiology-based explanation points somewhere else. In this episode, I speak with Dr Eric Helms about how to think through those conflicts without becoming dogmatic about any one source. Dr Helms is a PhD researcher in strength and hypertrophy, a coach of physique and strength athletes, and a high-level natural bodybuilder. Some of what we discuss: Why success leaves clues, not answers What we can and can’t learn from successful athletes and coaches Why individual hypertrophy studies can seem to conflict How to use reviews and position stands without outsourcing your judgement When physiology-based explanations sound more certain than the evidence allows This is the first part of a longer conversation with Eric. The second part moves further into the practical programming questions.

    The Science of Muscle Growth - and What It Means in Practice, with Professor Michael Roberts

    Every programme rests on some idea of what drives muscle growth. This episode looks at where the molecular and applied research supports that thinking - and where it does not. Professor Michael Roberts is a professor at Auburn University and one of the world's leading researchers on skeletal muscle hypertrophy, with a laboratory spanning cell culture, rodent models, and applied human research. In this episode, you will learn: What is happening inside a muscle cell when it grows Why mechanical tension appears to be central to hypertrophy What the evidence shows about testosterone and the androgen receptor in muscle Why women with much lower testosterone than men can still make similar relative gains with resistance training Where the evidence lands on rep ranges and weekly set volume Why drop sets are unlikely to add much once sufficient tension and volume are already in place What sarcoplasmic hypertrophy is, and when it may occur Why recent research suggests muscle fibres may grow by adding more myofibrils, not just by making existing ones bigger Key insight: Consistent mechanical tension, applied through a moderate rep range and sufficient weekly volume, appears to be a central driver of hypertrophy. The more complex the technique, the less likely it is to add much on top of that foundation.
