rep range doesnt make as big a dif as guys used 2 think, just from reading MD they say 60% of ur 1rm to failure for 4 sets is best. personally though, im on the fench about that. i go 6-10 rep range for bulking depending on exercise, for cutting i would say 12-15 and do 5 sets instead of 3/4. ive never done a big cut, this is just what ive read. good lcuk butteryexpecting another 9ibs down this week :P
