In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley dissect Reg Park’s 1950s “Mr. Universe Bulk Course”. Unlike the high-variation, single-set approach of Steve Reeves discussed in the previous episdoe, Reg Park’s plan featured fewer exercises but high set volume, low reps, and heavy loads.

The second half of the episode shifts into a deep dive on post-workout fatigue; what it actually is, what causes it, and why the common beliefs about fatigue and recovery might be wrong.

Key topics:

• The surprising recoverability of low rep, high set training
• Why post-workout fatigue is driven by calcium ion accumulation
• The four types of post-workout fatigue
• Why understanding the mechanisms of fatigue helps unlock more efficient programming

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley break down Steve Reeves’ favourite full-body routines from the early 1950s. They explore how Reeves trained each muscle with three different exercises, and why this multi-exercise, single-set approach might still be one of the most efficient ways to train if programmed correctly. The episode dives into the physiology behind exercise variation, the concept of neuromechanical matching, and how advanced lifters can apply full-body A/B splits to maximise hypertrophy.

Key topics:

• The difference between single sets per muscle vs. per exercise
• Why muscle hypertrophy and atrophy are muscle fibre-specific (not muscle-specific)
• How neuromechanical matching determines which fibres get trained in each exercise
• How to program more efficiently to achieve more growth with less work

In this episode of Hypertrophy: Past and Present, Jake Doleschal and Chris Beardsley examine Clancy Ross’ 1940s split set routine - an early experiment in dividing upper and lower body training that predated modern training splits. They break down how Ross evolved his training by splitting full-body workouts into AM/PM upper/lower sessions and discuss what this teaches us about fatigue management, muscle damage, and cardiovascular recovery.

Key topics:

• How Clancy Ross experimented with splitting his full body sessions into upper/lower
• The two types of supraspinal CNS fatigue (intra-workout vs. post-workout)
• How cardiovascular fitness governs your session capacity
• Why some lifters respond better to either full-body 3x per week or upper/lower 6x per week
