Hy guys I just wanted sone opinions on this circuit training routine. I am going to split my circuit training into a lower body one day and upper body another day. Upper body routine I have is Benchpress, Pulldowns, situps, pushup(diamond), seated rowing, skull crushersm bicep curls. I perform alll exercises with no rest, wait 1- 1.5 min then repeat the routine. Let me know what you guys think Should I be going to failure on each exercise and how many reps would I be doing for each exercise?? Thanks guys!!
