my larger body parts, chest, back, bi's, tri's all respond well to the 5x5 program so i'm wondering what range of reps should work best for forearms or calves?
it seems that going really heavy for these parts will lead to injury so is 12 - 18 a good range? or?
forearm curl (palms up then down)
calves - seated or standing machine
just started these twice a week, what do u think?
