026 How does insufficient sleep affect hypertrophy / atrophy?

In this episode of Hypertrophy: Past & Present, Jake and Chris dive into a Bill Pearl full-body routine, using it as a bridge between the pre-steroid silver era and the early anabolic era. From there, they shift into part two of their sleep series, unpacking how sleep loss influences muscle atrophy and recovery in natural lifters.

Key topics include:

• Bill Pearl’s 1957 full-body plan
• The difference between immobilisation/diet-induced atrophy vs stress/sleep-loss-induced atrophy 
• Practical programming changes when sleep is poor
• Why dieting hard while sleep-deprived is a recipe for muscle loss in naturals, and why enhanced lifters often don’t experience the same downside
