034 Voluntary activation deficit: exercise selection, muscle mass, and form

In this episode of Hypertrophy Past & Present, Jake and Chris analyse a Golden Era training plan attributed to Larry Scott and Vince Gironda, using it as a lens to explore how hypertrophy programming evolved after the introduction of anabolic drugs. From there, the conversation pivots into a deeper examination of modern debates around exercise selection, “redundant” movements, single vs multi joint training, and the current discussions around form. Chris introduces voluntary activation deficits as the unifying physiological principle.Key topics include:Larry Scott’s Golden Era full-body routineThe limits of motor unit recruitment and voluntary activation deficits"Redundant" exercisesWhy more total muscle mass in an exercise reduces local recruitmentThe form debate and how excessive technique focus can impair hypertrophy outcomes
