Stand with feet shoulder-width apart holding a resistance band in one hand anchored at chest height. Keep your core tight and shoulders down. Pull the band toward your torso while twisting your torso slightly toward the working side. Squeeze your back muscles at the end of the movement, then slowly return to the start. Repeat for reps, then switch sides.
