quick question.....i my quest for bicep growth, is it better to hit heavy weights @ the start of bicep training (after warm up) or hold off until the last couple of sets. Usually i warm up (2 sets of DB curls,light wt.) then move to ez curls w/ heavy weight, then concentration curls (med. wt.) ending w/hammers (by that time I'm spent) basically starting heavy then working down.......guess my question is this....... start heavy then work to light or reverse?
