Episode notes
1955 Arms Specialization Routine
- Peary Rader's 1955 arms specialization plan alternates curls and triceps extensions for 12 sets.
- This old-school method shows early understanding of targeting different arm muscle regions.
Exercise Biasing is Physiologically Impossible
- An exercise cannot fully activate all muscle fibers while biasing one region more.
- Biasing means some fibers are activated only in one exercise, not all fibers are activated by every exercise.
Implications of Biased Training
- If different exercises bias different regions, fibers unique to each need frequent training.
- Training a biased region once a week risks fiber atrophy if neglected otherwise.
