I think Vince Gironda was onto this strategy years ago without any of the studies behind it. His lifting was all about stretching under weight, the body drag curl, the "to the neck" barbell press and the sissy squat (which this article even mentions). i did a lot of these today when i hit chest. I have read another article recently that starts your next body part / workout by stretching the muscles of the last group exercised the workout before. if it works i will know it because i have certainly felt like i have come to a plateau overall and i switch routines at least every month. Still trying to figure out the best position / exercise to stretch out the triceps. I guess overhead dumbell is closest so far but still doesn't seem to stretch like a weighted outstretched fly would on pecs or a sissy squat on quads.
