In Episode 43 of Between Two Dumbbells, Skip Hill and Dr. Marv break down one of the most misunderstood topics in bodybuilding and strength training: high-rep training vs low-rep training for max muscle growth.
What actually counts as “high reps”?
Do higher reps build more muscle—or just endurance?
And how much do genetics really influence your hypertrophy potential?
Using real-world coaching experience and current research, we explain how rep ranges, volume, mechanical tension, and intensity interact to drive muscle hypertrophy, strength, and performance—especially for stubborn muscle groups like the legs.
We also dive into dry needling as a recovery and performance tool, explaining how it can improve muscle function, reduce pain, and help you train harder and more consistently.
Whether you’re a bodybuilder, powerlifter, CrossFit athlete, or just trying to build muscle efficiently, this episode will help you stop guessing and start training with intent.
