Anchor a resistance band at chest height behind you. Stand facing away from the anchor with a staggered stance and hold the band in one hand. Start with your elbow bent at about 90° and your hand near your chest. Press the band forward while simultaneously rotating your torso away from the working arm. Fully extend your arm at the end of the press and briefly pause. Slowly return to the starting position, untwisting your torso under control. Complete reps, then switch sides.
