OK here's an example of giant set workouts I did.....
Monday quads/hams
leg ext-squats-leg press-hack squats-leg ext finish quads before starting hams
sldl- laying leg curls-seated leg curls
Tues chest/triceps
Flat-incline-decline presses-incline flyes-cable flyes finish chest before starting triceps
CGBP-pushdowns-overhead ext
Wed off
Thurs back/biceps
Deadlifts-pulldowns-DB rows-hypers finish back then biceps
Standing curl-preacher curls-cable curls
Fri shoulders
Standing presses-side laterals-rear delts-shrugs
Also Friday you can throw in abs/calves if you can.

Everything is 3 sets, no rest between exercises only 1 minute or so between "sets", finish one bodypart before moving on to next. Exercises can be supplemented as you see fit, db's or barbell moves whatever is comfortable. At first your numbers will drop, but you'll be amazed at how fast the body adapts and you should be able to add weight every week, maybe not up to your regular numbers but up no less. No I only did these for 4-5 weeks at a time, then switched back to straight workouts. Anybody that does this will notice how much easier it is to breathe when you switch back also, believe it or not, you will be stronger, maybe not a big jump, but you'll notice a few more reps, lets say you're squatting 315 for 5-6 before, after you may hit 9-10.
