side-to-side chin

Stand with your feet shoulder-width apart and your knees slightly bent. Grasp a pull-up bar with an overhand grip, hands slightly wider than shoulder-width apart. Hang from the bar with your arms fully extended and your body relaxed. Pull yourself up by bending your elbows and bringing your chin towards the bar, while keeping your body straight. Once your chin is above the bar, lower yourself back down to the starting position. Repeat for the desired number of repetitions.
