I possess Chisell chewables which I use to train my jaw in order to obtain masseter hypertrophy. The problem is that I can't really overload the exercise with more resistance and my muscles become really used to increased volume quickly. For the first few trainings my jaw muscles would be totally exhausted after just a couple of "chews" while now I can pretty much chew indefinitely without even feeling it.

I know that dynamic exercises are much better for hypertrophy than static holds. But I thought about alternating rapid chews with static holds because I feel like static holds do a good job at pre-exhausting my muscles. My sample training "routine" would be: 90 seconds of rapid chews, 30 seconds of statt ic hold repeated 5 times. Last static hold would be done for as long as I can hold it, even if it's more than 30 seconds.

Wouldn't that be a more efficent way to achieve masseter hypertrophy? Main work still goes from rapid chews - I use static holds only to pre-exhaust my muscles. Also - I use to train 2 days in a row and then take a day off. Do you think I should do this more often like 5 days a week or everyday? Or maybe less often like 3 days a week? That would be it. Thank you in advance!
