Does anyone understand the science, the HOW and WHY, of why low reps and heavy weight builds muscle better?
Does it have to do with your body’s CO2 efficiency being reduced with every rep?
Or maybe a psychological/subconscious reason of the brain ‘seeing’ heavy weights?
Or does it have to do with work devided by time, and when people do high reps they usually do them at the same pace, thus work/time is less.
I’ve heard people say more muscle fibers are used, but assuming either high or low reps are done to failure, that’s not the case is it?
You see what I’m getting at… I’m wondering what the underlying mechanics at play are that cause this phenomenon to work.
