The workout move comes from Molly Sigman, who teaches the Pilates with Weights class at The Sports Club/LA–San Francisco. (For a full pilates workout, try our Mix-and-Match Pilates Moves for a Strong, Sleek Body.)
How to do it: Begin standing with feet about 4 feet apart; toes pointed out. With 5- to 8-pound dumbbells in each hand, hold the arms by your sides, palms facing out. Imagine sliding down a wall as you bend your knees deeply (knees should come over big and second toes) and raise your arms out to the sides at shoulder level in a straight line. Keep the head, shoulders, and hips straight and abs tightly engaged throughout the move. Return to starting position.
Repeat for 15 reps.
