I'm thinking of giving these a try. 5 sets, 5 reps each. For example if I want to do them for chest, I would do: 120 x 5 125 x 5 130 x 5 135 x 5 140 x 5 My friend recommended them and has said helps him increase his weights because he just adds 5 ibs to each set (125, 130..145) each workout. And if he can't do the full 5 reps on the last set then he'll re do the workout the week after and gets it no problem. Just seeing your guys opinions on these and if you got results trying them. Thinking of giving them a shot during next chest day, and if I like them i'll try them for shoulders aswell.
