In this episode of Hypertrophy Past & Present, Jake and Chris follow up last week's episode on drop sets by diving deeper into the physiology of fatigue and rest periods. Using an extreme high-volume routine from Serge Nubret, the episode explores why different exercises, rep ranges, and proximity to failure dramatically change the amount and type of fatigue that accumulates during training.

Key topics include:
• Serge Nubret’s ultra high-volume, short-rest training system
• The four major fatigue mechanisms involved in strength training
• Why “2-3 minute rest periods” may be an oversimplified recommendation
• How exercise selection changes optimal rest periods
• How clusters and reps in reserve reduce fatigue accumulation
• Why stretch-position exercises are more sensitive to muscle damage and calcium ion accumulation
