I rotate between the dvds and paper. I love LOVE the music in STS, especially the opener, just wakes me up. Usually i will do one full rotation with the dvd's, followed by a few months break and then will do them on paper. The paper workout for me is modified to other pieces of equipment in my gym. For example, I don't trust long bands (not referring to the small loops). I sub-out any band work to cables or springs on my Pilates reformer. (I'm lucky to have the space for a gym, and the equipment I have.) Chin-ups/pull-ups on a lat pulldown machine, push-ups will be done on my reformer and will use the bar at the end, and let the carriage move while doing the push-up. Causing a tremendous core fire-up (if that makes sense). My rebounder is used inbetween the longer segments on Meso 3, when I don't want to sit still. I have an issue with deadlifts, no matter how I train with them, I will eventually get a back tweak. I modify that to a one-leg deadlift using kettlebells and stick in the balance challenge. All my squats are done on a squat machine, so usually I never get over 8 to 10, because I'm lifting over 180 pounds. If I use the dvds, I will be using a barbell and keep it light. Think about all the ways you can tweak this fantastic set.
I have changed this workout so many times, which keeps it very fresh for me. Its my go-to and I ended up buying a full second set, because I'm afraid I'm wearing out my original (I guess a good thing). I worry that eventually everything will go to streaming, and that will be an issue of wifi for me.
