Sort of a beginner in the training world so this question may be a bit elementary so, I'll apologize now if it is.....
I understand that high reps/light weight is more for tone and low reps/heavy is for bulk and strength. My question is why?
Do high reps hit a different part or make the muscle react differently than the low reps? Why do high reps make you feels as if you just lifted a cow while low reps are kind of bla?
I apologize again if this is a jr question but, I am trying to figure this thing out.
Thanx for your input.
