Why Muscle Size Doesn’t Fully Explain Strength, with Professor Paul Comfort

How many sets does a muscle need to grow, and how much does each extra set add? In this episode of Stronger With Time, I speak with Dr Jake Remmert about volume, frequency and effort, and what the research means for how you program for muscle growth. Jake is an exercise physiology professor at Illinois State University and a strength and physique coach. He did his PhD in Dr Mike Zourdos's Muscle Physiology Laboratory at Florida Atlantic University, is one of the primary authors of the recent meta regression on per session training volume, and co-authored the dose response analysis on weekly volume, frequency and proximity to failure with Josh Pelland and Zac Robinson. Throughout, Jake makes the case that the big rocks (effort, recoverable volume and consistency over time) matter more than the fine details.

Professor Roger Enoka is one of the world’s leading authorities on the neuromuscular system and has spent more than four decades studying how the nervous system produces movement, strength and fatigue. He is the author of Neuromechanics of Human Movement, now in its sixth edition. In this episode of Stronger With Time, we discuss why Type II muscle fibres are not simply high-threshold motor units, why light and heavy loads taken to failure can produce similar muscle growth despite differences in motor unit activity, and what can limit your ability to continue a set as you approach failure. In this episode, we discuss: What a motor unit is, and why muscle fibre type and recruitment threshold are not the same thing

How much of what we do in the gym today is genuinely new, and how much has been around for decades? In this episode of Stronger With Time, I speak with Dr Conor Heffernan about where many of the training ideas we now take for granted came from, how they changed over time, and what their history can teach us about how we train today. Conor is a historian and sociologist of sport at Ulster University whose work focuses on the history of strength training and physical culture. He is the author of The History of Physical Culture and When Fitness Went Global, and writes at Physical Culture Study.

VO2 max matters, but what else determines endurance, and how should you train for it?

Most of the attention in training goes to the workout itself. But what happens after the workout that determines the result you get from it? In this episode of Stronger With Time, Tony speaks with Professor John Hawley, one of the most influential figures in exercise metabolism, about what four decades of research can teach us about how we train, fuel and recover. John is a Distinguished Professor at Australian Catholic University in Melbourne, where he directs the Centre for Human Metabolism and Performance. His research spans how exercise and diet regulate fat and carbohydrate metabolism in skeletal muscle, the molecular basis of training adaptation, circadian biology and nutrient timing, and how exercise improves insulin action. John helped run some of the pioneering interval-training studies in Cape Town in the 1990s and has spent the decades since studying the mechanisms behind how training works.
