Dante C. Doggcrapp workout which is mostly 'rest pause' , he has you take 15 deep breaths between the 3 rest pause sets. Example; set of 8, rack weight, sit up, take 15 deep breaths, as many resp as you can, repeat 1 more time. When you hit 15 or more total reps you add weight the next workout. As long as your making progress on the total reps each workout and adding weight as you hit target of 15 you can keep using that lift, ie. bench. If you go backwords or even hit the same reps you have to change the lift ie. go from bench to db bench. One of the best workouts Ive ever used, made the best progress ever. Problem is I was to old when I discovered this and kept getting injured due to the fast increases in weight being used.
