RE: slow/heavy
Like Marnie, I have done the Chest/Back and then Triceps/Biceps back to back. It's tiring, but sometimes it has been worth it. I would do it again in a pinch. But I would never do all three in a row! I have also done the two upper body PS tapes in a row. It's not too bad. In fact, I did it last weekend. I start with Back, then stop the tape, do Chest, Shoulders, and Triceps, and then put the other tape back in and finish with Biceps and Abs. It takes an hour and a half since I skip one of the warmups and one of the cooldowns. I think it's a great workout and is no longer than say, BodyMax.
