I've had acouple people say I perform a lot of iso moves and acouple ask sets. Generally I perform 3 or 4 sets, depending on how well the previous sets felt. The most I every perform is 5, and usually that is with the medium or light sets. On my chest I usually perform 3-4 sets, my arms 3-4 sets 5 if I really didn't feel anything the first 3 or 4, my back 3-4 sets, my legs usually 4 sets, maybe 5 if I'm really feeling good, my shoulders 3-4 sets. as far as the routine, if you don't agree with the routine what do you suggest? This routine was taken from a muscle and fitness magaizine, and was aimed, by the magazine, at building bigger arms, but I'm open to other routines.
