Why You Should Go: Workouts you've tried: all of them. Workouts that worked: none of them. It's time to turn to the tried-and-true exercise known as Pilates for muscle-strenghtening, core-craving results. Start with four beginner classes at Centerpoint Pilates in Rittenhouse Square. 

Why You'll Love It: You’ll be inspired by the natural grace of former dancer (and owner) Margie Foley. Her jealousy-inducing posture can be achieved through the studio’s practice of Fletcher method of Pilates. By incorporating towel work, mats, and barre work with traditional exercises, you’ll tone your core, firm your arms, and de-jiggle that wiggle. 

How You’ll Get Fit: Arms strengthen and legs lengthen in small group reformer classes in which a machine’s springs add resistance and assist your workout. Pair that with mat workouts that target your whole body (especially those abs) or a yoga class that guides you through fundamental postures, core work, and vigorous standing sequences to prepare you for more advanced twists, inversions and flying lotus poses.
