Stand with your feet farther than hip-width apart, feet and knees turned out comfortably from the hips, abs tight. Place a workout band across your lower back, holding an end in each hand and wrapped around your palm, elbows bent and hands on hips. Bend your knees into a plié as you lean your torso to the left and raise your right arm overhead [shown]. Straighten your legs and lower your right hand to the starting position. Do 5 to 10 reps, then switch sides.
