I crush every muscle group that I am working until I can take it extra sets if I want them I usually do. Use heavy weights move slowly with purpose my last set will be low weight and ripped out till I need total help removing the bar or re racking it. Min between sets. Three min between exercises I can usually handle the stress quite well when I'm on. Chest/Tricept Quads/calves. Back/bicept Shoulders/abs one day off and repeat.
