Episode Details

In this episode of Hypertrophy Past & Present, Jake and Chris unpack a new hypertrophy study that illustrates how fatigue doesn’t just make training harder but can directly reduce the hypertrophic stimulus by lowering single-fibre mechanical tension. The episode opens in the Silver Era again with Henry Paschal’s 1950 “busy person” program then pivots into the core discussion: why fatigue mechanisms (CNS and calcium-ion related) dampen muscle growth, and what this implies for exercise order, rep ranges, and advanced training methods. 

Key topics include:

• Henry Paschal’s 1950 routine
• A new “repetition duration” study
• How CNS fatigue and calcium-ion fatigue both serve the same function
• Why max effort and slow velocity don’t always equal max recruitment and max tension
• Programming implications: exercise order, rep ranges, RIR, clusters, and isometrics
