Face the chair back and hold it with both hands at arm’s length, feet hip-width apart and turned out, abs pulled in. Shift your weight to your right foot and point your left toe back, keeping your legs straight [3A]. Keeping your hips still, lift your left leg a few inches off the floor into an ara- besque. Squeeze your glutes and keep your shoulders back and down [3B]. Slowly lower your left toe to the floor, ending in the starting position. Do 5 to 10 lifts, then switch legs.
