The pull up is a popular exercise that develops a strong and defined upper body. It’s a staple movement that everyone should strive to achieve. Grasp the bar with an overhand grip and begin from a dead hang with your arms fully extended, about shoulder width apart and your palms facing away from you. Pull up toward the bar by bending at the arms and clear it with your chin. Pause at the top of the exercise and then lower back down under control. Return to the starting position and repeat. Your back and biceps benefit, but so will your shoulders and core muscles.
