Medium high reps are usefull in converting type 2b cells into fast-twitch. Offcourse we are talkin about people that happen to have a lot of them 'intermediate' cells, pure red musclefibre will not contvert and grow much less than white fiber, HOWEVER they do grow and theror it would be usefull for people with more red thjan white fibers to LOW and HIGH reps. While the white fibers have more RELATIVER growth potential, if u have a lot of red fibers too, this outnumbers the whites and can give you ABSOLUTELY more musclemass...
21's some claim it's the bomb others say its just burn and lactic acid. My feeling is that you can do them best every now and than to get the best results from them
About the neurologic learning process. You shouldnt change your exercise too much otherwise indeed you have to learn again optimized recruitment patterns.
I think its best to stick to an exercise as long as you make reasonable progress with it.
Hwever some pro's claimed they could finally build a refined back when they threw in muscle confusion, doing different exercises all the time in random order and reps... Maybe this is for pro's only as you already have a "memory" of known and trained neurologic recruitment pathways and you need some special treatment to learn new tricks to the old dog.
