In fact there is a training program that sort’ve relies on this principle. The program was designed by Fred “Dr Squat” Hatfield. It involves tri-setting 3 exercises. Pick one bodypart. The first exercise must be a heavy compound type movement, such as squats, bench press, shoulder press etc. The 2nd exercise is still a compound movement but a slightly different variation of the 1st for example: leg press, hack squats, dumbell incline press etc. The last exercise is an isolation movement…leg extension, flyes, laterals etc.
Now what you do is do the first exercise for a heavy set of 4-6 reps. Immediately move on to the second exercise and do a set of 10-12 reps. After this immediately move on to the 3rd exercise and do a set of 30-40 reps.
The idea is that with each set you’re hitting different muscle fibers so while your type IIA fibers are working in the 2nd set your type IIB fibers are recovering from the 1st. While your type I fibers are working in the 3rd set your type II’s are recovering. The theory is that you should be able to go through 3 cycles or 3 entitre sets of this continuously without any rest using roughly the same weight but I’ve found I need to rest at least a minute after the last exercise but I am very fast twitch and need more rest in between sets then most.
Make sure you’re using exercises that work the same bodypart, here are some examples…
Quadriceps: squat, leg press, leg extension
Hamstrings: Deadlift, Russian good mornings, leg curls
Chest: Bench press, incline dumbell press, flat bench flyes
Back: Bent over rows, pull-ups, pullovers
Shoulders: Seated military press, upright rows, side laterals
Biceps: standing barbell curls, preacher curls, lying cable curls
Triceps: close grip bench press, skullcrushers, tricep pushdowns.
