I have been doing the three DVDs once a week now for 6 weeks, and I strongly recommend them. I have lost an inch on each of my thighs and an inch and one-half on my waist. My butt is much firmer as well. I think the leg and abs work is really strong, but the upper body is just maintenance at best, so I do DM and BM2 the upperbody premixes with cardio, and a Kelly C-M circuit workout. I also follow the 30 min. Physique 57 workouts with 30 min. of light cardio. I will continue this until shock cardio comes out and then I will go back to STS (I did STS from February through June) rotating with the shock cardio if I can do any of it (it may be too much impact for me). I also intend to use the Physique 57 workouts instead of the STS legs, because I didn't get any noticeable changes with STS. Never had doms, even with 60 lbs. squats in meso 3, 75 lbs. deadlifts. And I cannot do the plyo legs--bad knees.
