In this episode of Hypertrophy: Past and Present, Jake and Chris revisit Joe Weider’s early 1940 full-body program before breaking down the central problem that all split routines face: supraspinal CNS fatigue.

Key topics include:

• How calcium-ion–related fatigue and inflammation create global CNS fatigue
• Why back-to-back training days reduce recruitment, even for unrelated muscles
• Why full-body AAA and AB formats avoid these issues

In this episode of Hypertrophy: Past and Present, Jake and Chris explore Sig Klein’s early A/B full body routine from the pre-steroid bodybuilding era before examining the claim that elevated myofibrillar protein synthesis blunts the effectiveness of subsequent workouts.

Key topics include:

• Sig Klein’s beginner routine
•  The difference between myofibrillar protein synthesis and hypertrophy stimulus
• What comparing one vs three set studies shows us about elevated synthesis timelines
• Why any overlap effect is small (and irrelevant for single-set workouts)
• Why the weekly net stimulus still favours three times per week over two times per week training

In this episode of Hypertrophy: Past and Present, Jake and Chris explore the lesser-known silver-era bodybuilder Floyd Page’s 1952 full-body routine before unpacking the topic of training frequency, long-term training studies, and physiological models.

Key topics include:

• Floyd Page’s 1952 “favourite routine” and its historical context
• The non-linear dose-response of sets and why frequency changes the outcome
• Physiological models vs. long-term training study data
• What the Currier (2023) network meta-analysis really shows
• Why three times per week consistently beats once per week, and where two times fits in
• The role of models in filling research gaps and guiding practical programming
• How to navigate conflicting information 

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley unpack one of Peary Rader’s Silver Era “advanced beginner” routines, before a deep dive into the principle of Neuromechanical Matching.

Key topics include:

• What Rader’s “advanced beginner” (intermediate) plan looked like
• A deep dive into the neuromechanical matching principle
• Common misconceptions and critiques of NMM
• How it interacts with the size principle and fatigue
• Practical implications for programming

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley break down an isometric method from bodybuilding legend and first Mr Universe, John Grimek. They explore how maximal-effort isometrics can stimulate muscle growth and the key differences between overcoming and yielding isometrics.

Key topics include:

• How isometrics produce hypertrophy
• The role of joint angle specificity
• Yielding isometrics versus overcoming isometrics 
• Practical ways to program isometrics

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley dive into a 1955 arm specialization routine from Peary Rader and use it as a launchpad to challenge one of the most common misconceptions in hypertrophy programming today.

They explore whether exercises can “bias” specific muscle regions, and what the implications are for hypertrophy programming.

Key topics include:

• What it really means to “bias” a region of a muscle
• Why the idea that a single exercise can train the whole muscle and “bias” a region is false
• The critical role of voluntary activation deficits and neuromechanical matching
• Practical implications for programming, periodisation, and avoiding fibre-specific atrophy

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley unpack the very first York Barbell course, discussing its warm-up approach and how it compares to other silver era routines.

The second half of the episode zooms out to explore warm-ups more broadly, what they actually do (and don’t do), whether they affect hypertrophy, and why most warm-up advice might be misguided.

Key topics:

• The three physiological effects of warming up: temperature, PAP, and PAPE
• Why most common warm-up routines may do nothing for hypertrophy or injury prevention
• How to structure warm-ups that actually do something

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley break down a pre-steroid bulking routine from Alan Stephen, an underrated Silver Era bodybuilder who trained with a pretty unique method. They explore how this high volume, low rep program makes sense with the stimulating reps model, and use it as a springboard to unpack one of the most misunderstood training concepts: work capacity.

Key Topics:
• The three definitions of “work capacity” and which one actually matters
• Why volume doesn’t improve your ability to do more work
• How cardiovascular endurance (and not higher reps or more sets) influences gym performance

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley explore whether full body training can be done every day, and what that really looks like. Drawing inspiration from Bronze Era strongman George Hackenschmidt, they unpack creative strategies for making high frequency training work.

Key Topics:

• How training every day differs from traditional 3x per week programming
• How MYOPS behaves and whether it must return to baseline before training again
• What programming variables to consider when training full body daily

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley return to Reg Park, but this time explore one of his most advanced programs. They compare this higher volume plan to Park’s earlier abbreviated routine before exploring whether all training programs eventually lead to the same outcome, and which variables actually determine your muscular potential.

Key Topics:

• How Reg Park’s exercise selection evolved from bulk to shape
• The physiology behind fibre-specific muscle damage
• Why exercise selection and frequency determine your end result
• What volume actually does (and doesn’t) achieve when it comes to muscle growth
• Why different exercises once a week is often worse than repeating the same exercise twice
