for all its worth im pretty new to this and i have been doing 7 to 10 reps in 4 sets each excercise increasing in weight as i go and also do drop sets sometimes when im finished the 4 sets starting at last weight lifted 8 reps then change to next weight down 8 sets and so on till start weight reached then either stay at same weight or drop one more and burn out really gets the blood and sweat flowing
