I am changing my routine now as I have become a little stag. My question is this though: There are a ton of studies that say to only lift sayt 1 body part every 6 or 7 days to be effective. Yet there are tons of studies that say to lift a part 2 to 3x per week. I just read for example that Arnold lifted each body part 3x per week on a 6 on 1 off split. Now does anyone lift each part this frequently anymore, and what have been the results?
