Hypertrophy Past and Present

In this episode of Hypertrophy Past & Present, Jake and Chris begin with a 1972 routine from Bradley J. Steiner and discuss what makes it one of the more sensible "golden era" bodybuilding programs they've reviewed so far and whether splitting exercises across consecutive days is likely to be more or less effective than performing all exercises in a single workout. 
The conversation then shifts towards the concept of "training hard." Jake and Chris unpack what hard training actually means, why RPE is often a poor proxy for hypertrophy, and how chasing "hard training" can unintentionally encourage fatigue instead of productive training.
Key topics include:
 Bradley J. Steiner's minimalist 1972 bodybuilding routine 
 Whether splitting workouts across consecutive days improves stimulus to fatigue ratio
 Why RPE and reps in reserve are not interchangeable 
 How cardiovascular fatigue, burning sensations, and instability can increase effort while reducing stimulus 
 The concept of "quality over quantity" as a better way to think about muscle growth 
 Why telling people to "train harder" may actually make their programs less effective

In this episode of Hypertrophy Past & Present, Jake and Chris begin with Steve Michalik’s enormous 1972 Mr. America routine and why silver-era routines are the best data set for natural training routines. From there, Jake and Chris explore how the hypertrophy dose-response relationship interacts with the stimulating reps model. They discuss why the second and third sets provide progressively less growth stimulus, whether this means they contain fewer stimulating repetitions, and how the answer depends on whether the reduction is caused by fatigue or stimulus saturation.
Key topics include:
• Steve Michalik’s 1972 Mr. America routine
• How training status changes the number of potentially stimulating repetitions
• Combining the stimulating reps and weekly net stimulus models
• Why fewer hypertrophy gains from a second set does not necessarily mean fewer stimulating reps
• The difference between fatigue and stimulus saturation
• How longer rest periods can make a second set more effective
• Why making the second set better makes later sets less valuable
• Why back-off sets are an inefficient method for doing a second set
• How to achieve more hypertrophy stimulus with fewer total sets

In this episode of Hypertrophy Past & Present, Jake and Chris begin with Alan Stephan’s classic Silver Era full-body routine, which he reportedly followed for years while building enormous strength and muscle. This leads into a deeper discussion about exercise variation, whether exercises really “stop working”, and why good natural bodybuilding programs often end up looking repetitive.
From there, Jake and Chris move into one of the most important physiological arguments behind the stimulating reps model: hypertrophy is not a whole-muscle phenomenon, but a muscle-fibre-specific one. They discuss why this matters for understanding mechanical tension, light-load training to failure, sarcomerogenesis, stretch-mediated hypertrophy, force-velocity relationships, fatigue, exercise selection, and training frequency.
Key topics include:
• Alan Stephan’s 1940s full-body routine
• Why an exercise does not “stop working” just because progress slows
• How single-fibre mechanical tension explains the stimulating reps model
• Sarcomerogenesis, passive tension, titin, and stretch-mediated growth
• Why hypertrophy and sarcomerogenesis are not the same thing
• How cross-bridge formation and shortening velocity influence fibre tension
• Why exercise selection matters if hypertrophy is fibre-specific
• How Silver Era routines line up with modern physiology

In this episode of Hypertrophy Past & Present, Jake and Chris begin with a classic Clancy Ross full-body routine from the Silver Era, then move into a discussion about training frequency, mTOR, muscle protein synthesis, and whether training again before the previous hypertrophy stimulus has “finished” is actually a problem.
Key topics include:
• Clancy Ross’ 1940s full-body single set routine
• Whether training a muscle every 48 hours can blunt hypertrophy
• How repeated bout effect studies can be misapplied to training frequency
• Why mTOR signalling is not the same thing as muscle growth
• The role of oxidative stress and inflammation in post-workout recovery
• How volume, frequency, stress, dieting, and athletic workloads affect recovery
• Why the best training frequency is limited by recovery

In this episode of Hypertrophy Past & Present, Jake and Chris discuss a full body training A/A/A program from Steve Reeves before exploring how to choose between repeating the same full body workout three times per week or alternating between two different full body workouts.
Key topics include:
• Steve Reeves’ full body AAA routine
• Why many old-school routines online should be treated cautiously
• The lying dumbbell front raise and how it may train different regions of the chest
• Why exercise selection should come before choosing a training split
• Full body AAA vs full body ABA/BAB 
• The problem with doing multiple sets of the same exercise versus using more exercise variety
• How spinal CNS fatigue, supraspinal CNS fatigue, metabolites, and calcium ion accumulation affect hypertrophy training
• How advanced lifters can use priorities to decide which exercises stay the same and which rotate
