066 Do you need to feel a muscle for it to grow?

In this episode of Hypertrophy Past & Present, Jake and Chris begin with another Leroy Colbert routine, this time examining an over 100 set silver-era routine. The conversation then explores whether you actually need to “feel” a muscle for it to grow, what the pump can tell us about muscle recruitment, and where the mind-muscle connection may or may not be useful.

Key topics include:

  • Leroy Colbert’s extreme 10-set-per-exercise Silver Era routine

  • Why “feeling” a muscle and getting a pump are not necessarily the same thing

  • Why stretch, cramping, and soreness can be misleading indicators of muscle activation

  • Mind-muscle connection, internal focus, and how they change muscle recruitment

  • Why exercise selection may be a better solution than trying to force a mind-muscle connection

  • When mind-muscle connection and isometric contractions may actually be useful

  • Why constantly using a mind-muscle connection can interfere with progressive overload

  • Why pre-fatiguing a muscle doesn’t cause the other muscles in a compound exercise to “do more work”

  • What motor learning research tells us about training and practising skills while fatigued
