A 50-minute advanced Pilates workout, taught by world-renowned Pilates instructor Rael Isacowitz.

Intermediate to advanced Pilates enthusiasts. Seriously. This one's tough!

There aren't that many intermediate and advanced Pilates workouts on the market and there are even less that deliver a routine that really challenges. Even worse, the ones that do offer difficult exercises, such as the Swan, present them in highly advanced versions that are flashy but potentially dangerous for the at-home user who hasn't taken mat classes in a studio. That's why Rael Isacowitz's System 27 is a must-have for any experienced Pilates enthusiast who is discouraged by the mediocrity of other Pilates DVDs. The moves are pure Pilates, presented so that they flow from one exercise to the next — the way they should be practiced. This keeps your core fully engaged for much of the workout. Because your abs are constantly working, even the easier versions of exercises like the Hundred will lead to fatigue — you're never given a chance to take a break! Isacowitz presents 27 exercises with enthusiasm, style and precision, and while they will all be familiar (who hasn't done the Corkscrew, Criss-Crosses or Leg Circles a million times by now?), what won't be as familiar is how difficult they are here! If you have reached a slump in your at-home Pilates routine and you want to kick it up a notch — safely — this is the DVD you've been waiting for!
