TO WHITTLE THE WAIST: SPINE TWISTS

These seated twists work in two ways to give you a long, lean silhouette. “Holding the band engages the back and chest muscles, while the twist works the obliques,” says Driver.

To do: Sit with your legs straight. Wrap the band around your back and cross it over. With your arms to the sides, twist your torso as far as you can to one side, keeping your legs flat, then twist to the other side. Do 5 reps.
