With chic studios in New York City, the Hamptons, and Los Angeles, this barre- and Pilates-inspired “interval overload” technique promises visible results in as few as eight sessions—which is why fit celebs like Kelly Ripa, Stacy Keibler, and Emmy Rossum are such big fans. The Physique 57: Classic 57-Minute Workout DVD($24.95; physique57.com) is designed for every fitness level and is the perfect introduction to the technique.
What to expect: You'll learn all of the primary Physique 57 positions while challenging every major muscle group—arms, thighs, butt, and abs—with a lot of repetitions and a lot of plies.
You'll need: A Physique 57 exercise ball (or similar small, squishy ball), a waist-high sturdy chair,, a cushion or thick towel, and a pair of 3- to 5-pound dumbbells.
