Does training at different muscle lengths affect how quickly the muscles grow? In this interview, Menno Henselmans and I discuss new research on stretch-mediated hypertrophy and the role muscle lengths play in combination with mechanical tension. This is something Mike Israetel and I briefly touched on in our recent interview on partial reps versus full-ROM training, but in this discussion, Menno and I talk about the latest science of resistance training at long muscle lengths, including a new meta-analysis that isn’t published yet.

Menno has been on my podcast many times on my podcast, but in case you’re not familiar with him, he’s a former business consultant turned international public speaker, educator, writer, published scientist, and physique coach who’s passionate about helping serious athletes attain their ideal physiques.

In this interview, Menno and I talk about . . .

- What stretch-mediated hypertrophy is, possible mechanisms behind it, and whether you should modify your training to incorporate more of it

- Active tension versus passive tension

- The actual reason why full-ROM training is effective

- Specific guidance on how to modify and tweak exercises for more loaded stretching (including Bayesian curls, flyes, leg extension tips, and “skull-overs”)

- Static stretching between sets (its effects and whether you should do it)

- And more . . .

So if you want to learn what the science says about training at longer muscle lengths, and how to incorporate more stretch-mediated hypertrophy in your program, definitely check out this interview!
