If your house was burning and you had managed to save your kids, pets, photos, etc, but had time to only grab ONE video, which would it be? I own close to a hundred fitness videos- cardio, strength, pilates and yoga, but Pilates Mix would be my choice without even thinking about it. I agree with all the comments by the previous reviewers, so I won't go on to repeat their comments. The program is tough, it's very effective, and best of all, it is unique. I usually do program 1 plus the bonus on one day, skip a day, do program 2 plus bonus, skip another day, and then do a traditional full Pilates. I've been doing this since Pilates Mix first came out, and I've lost 2 inches from both waist and thighs, even though I had felt as though I was very fit before starting this. Another big plus is that my entire back is so much stronger now. So many fitness videos focus on strenthening or toning strictly what you see in the mirror- abs, arms, thighs. This program is well balanced for full body benefits. As previously noted, this is NOT for beginners. Some of the sequences are very fast-paced.Although modifications for some exercises are shown, all too often the viewer is in a position such as plank or down dog variation, and unable to see the TV screen. Even in the modifified versions, a good functional base of core strength is necessary to maintain good form. Anyone trying this who hasn't already been working at the intermediate level of Pilates could easily strain their back. Anyone with wrist problems might want to avoid Pilates Mix, (or at least, skip Program 1) Program 1 has pushups and lots of plank and side plank variations that may put too much stress on painful wirsts.
