A pull-up is an upper-body strength exercise. The pull-up is a closed-chain movement where the body is suspended by the hands, gripping a bar or other implement at a distance typically wider than shoulder-width, and pulled up. As this happens, the elbows flex and the shoulders adduct and

. A pull-up may be performed with overhand (pronated), underhand (supinated)—sometimes referred to as a chin-up—neutral, or rotating hand position. Pull-ups are used by some organizations as a component of fitness tests, and as a conditioning activity for some sports.

Movement

Beginning by hanging from the bar, the body is pulled up vertically. From the top position, the participant lowers their body until the arms and shoulders are fully extended. The end range of motion at the top end may be chin over bar or higher, such as chest to bar. Pull-ups are a closed-chain, compound movement involving flexion at the elbow and adduction or extension of the shoulder joint. The trapezius, infraspinatus, and

brachialis The brachialis (brachialis anticus), also known as the Teichmann muscle, is a muscle in the upper arm that flexes the elbow. It lies deeper than the biceps brachii, and makes up part of the floor of the region known as the cubital fossa (elbow pi ...

experienced maximum activity at the top of the movement. There is similarity to the pull-down in terms of the muscle activation. A 2017 study found that pronated grip activated the middle trapezius more than the neutral grip, but that overall the muscle activation of different grip variants was similar. Muscle activation is significantly different depending on whether the pull-up is completed individually or in a set without resting between repetitions, which is more efficient due to muscle and tendon strech-shortening rebound. Overhead movements such as pull-ups reduce the subacrominal space and create a risk of

, neutral, or pronated grip; devices allow the grip to rotate during the pull-up. The pull-up performed with an supinated grip is sometimes called a chin-up. A pull-up may be completed using different widths of hand position; studies have found that participants freely choose a grip that is between 20 and 50 percent wider than shoulder width. A grip that is too wide could increase the injury risk or reduce the number of repetitions able to be completed due to lengthening the lever arm.

Equipment

Pull-ups are commonly performed using a bar; doorway mounted bars are sold for use in home gyms. They can also be completed by grasping towels, rotating handles or

Use

Pull-ups are a common way to measure upper body strength, endurance, and strength-to-weight ratio. The strength to do a pull-up is correlated with job-related tasks in some careers such as

, gymnastics, rope climbing, rowing, and swimming. They are also used by police and military to increase muscular strength among their members. Some organizations allow women to use a flexed arm hang as a substitute for a pull up in fitness tests after discovering that few female recruits could complete a pull-up. According to a 2003 study in college-age women, one third of participants were able to complete a pull-up after a twelve-week full-body strength training program.
