In this episode of Hypertrophy: Past and Present, Jake and Chris discuss Sig Klein’s extensive routine and use it as a springboard to tackle one of the biggest programming questions: how much exercise variety do you really need for maximal growth?
Key topics include:
- How neuromechanical matching explains which motor units get recruited first
- Voluntary activation deficits - why bigger muscles and bigger lifts mean some motor units aren't recruited
- How to use unilateral work to meaningfully increase recruitment
- Why some muscles require greater exercise variation than others
