Actually just read some stuff bout it. Its supposed to decrease the rate of lactic acid build up, thus allowing you to work out harder (more reps). Which if you think about it, those last few reps are where you're going to be tearing the muscle up and therefore giving you muscles the stimulus to grow. Sounds like the idea behind this is solid, not sure if it actually works. Someone chime in on this thread, im really interested in the stuff & wanna see what you older wiser ppl think about it.
