do you belive in training by maximal reps of faliure for core movements? i know most football players and coaches suggest this to build our needed type of explosive muscle fiber, obviuosly it works but it seems i go through platues liek this, for example im currently repping 250 for faliure sets, say 6 or 7 (faliure at 7 after 3 sets befor) and ive been stuck here now for a while, should i change up and increase my number of reps for a while to bust out of this platuea?
