I have to disagree, bodybuilders follow a high rep routine for the most part.
I dont why the burning feeling kicks in, you could be right about the lactic acid, but eating away??
20 rep squats, would definately make your leg muslces recruit and activate more and more muscle fibers each rep. So 20 reps, would definately activate ALOT more Muscle fiber then a 5 rep would. Thats why high reps = growth.
If you have some solid info to back it up, please share with me.
