Stand with your back against the wall and hold one dumbbell in each hand, with your palms facing away from you. Walk your feet out away from the wall and slide your back down the wall so that your legs are shoulder-width apart and your knees are bent at 90 degrees. Hold this position. Once you're holding the wall sit, curl the dumbbells up to your shoulders without moving your upper arm. Once the dumbbells reach your shoulders, return them back to the starting position.
