This barre-based toning done in micro-movements (up an inch, down an inch) targets the butt, legs, and core so you can sculpt a dancer’s body. Most classes last about an hour, incorporate upper body work, and use props like exercise balls and hand weights. Trust us—you’ll feel the burn.

Plié in studios like Pure Barre (purebarre.com) and Cardio Barre (cardiobarre.com) or at gyms like Equinox (equinox.com) and Crunch (crunch.com).
