ok, we all know that we can't "shape" a muscle, or do high reps for toning. but like some people i talk to say that you can build different "qualities" of muscle. like i was thinking and it does rather make sense. like have you noticed how powerlifters have muscles that are really blocky and bad looking? and they all train within the 1-4 rep range. but body builders tend to train in a higher rep range. so some of the "trainers" that i've talked to say lower reps do build muscle, but just not as good quality. is there any truth is this? i feel that i'll have some good responses from chris mason and mac...
