Super high reps of anything sounds like working hard for the sake of working hard instead of working smart. Strength and conditioning training should be done at the minimum effect dose to achieve your goals as well as safe as possible so you can concentrate your efforts in your skilled training. Not only would 4000 bodyweight squats everyday take for-fucking-ever and take precious time away from your skilled training(you know, the shit that actually makes you a better fighter) but it also sounds like a recipe for developing an overuse injury.
Yeah i know 4000 is way above crazy, i was just using it as an example of an actual nutty amount of reps, to show 100 aint really shit
