Movement

What the movement is

One large fitness-testing programme set out the pull-up in its test rules7. The programme tested 154,659 young Norwegian men and women at conscript selection7. Its pull-up test began from a vertical hang with straight arms and an overhand grasp7. The chin had to rise over the beam, and kicking or swinging was not allowed7.

In 21 men and 4 women, the elbow moved through a mean range of about 93 degrees in the pull-up1. In the chin-up, the mean range was about 101 degrees1.

The names studies give each grip

Studies name the grips in different ways, and this page keeps the name each study used4,8. One movement study calls a shoulder-width pull-up with the palms forward a front-grip pull-up4. It calls one with the palms backward a reverse-grip pull-up4. A modelling study describes its front-grip and wide-grip pull-ups as pronated and its reverse-grip pull-up as supinated8. Pronation means turning the forearm so the palm faces down, and supination means turning it so the palm faces up.

How the shoulder blade moves

One study tracked the scapula (shoulder blade) in eleven healthy men who did pull-ups in regular training4. It measured protraction, drawing the shoulder blade forward around the rib cage, and retraction, drawing it back toward the spine4. The range of this movement on the way up differed with the technique4:

Range of protraction and retraction on the way upFront grip (palms forward, shoulder width)22 degreesReverse grip (palms backward)17 degreesWide grip10 degrees
Range of protraction and retraction on the way up (degrees). Bars start at zero; the table below gives each value with its source.
TechniqueRange of protraction and retraction on the way up
Front grip (palms forward, shoulder width)22 degrees4
Reverse grip (palms backward)17 degrees4
Wide grip10 degrees4

How kipping changes the movement

In eleven athletes, the maximum hip angle was about 49 degrees greater in the kipping pull-up than in the standard pull-up3. The maximum knee angle was about 57 degrees greater3.

What it loads

The most active muscles

One study of 21 men and 4 women recorded seven muscles with electromyography (EMG), which measures a muscle’s activity from its electrical signals1. Each muscle was scored against its maximal voluntary isometric contraction, its hardest effort while the joint stays still1. The ranges cover a pull-up, a chin-up and a pull-up on rotating handles1:

MuscleAverage activity, % of maximal voluntary isometric contraction
Latissimus dorsi117 to 1301
Biceps brachii (front of the upper arm)78 to 961
Infraspinatus (a rotator cuff muscle)71 to 791
Lower trapezius (pulls the shoulder blade down)45 to 561
Pectoralis major (the large chest muscle)44 to 571
Erector spinae (long muscles beside the spine)39 to 411
External oblique (a flat muscle at the side of the abdomen)31 to 351

The same study looked at when each muscle peaked1. The timing suggested that the lower trapezius and pectoralis major started pull-ups and chin-ups1. It suggested that biceps brachii and latissimus dorsi recruitment completed them1.

What the grip changes

Two studies reached different results on what the grip changes1,2. In 21 men and 4 women, the pectoralis major and biceps brachii were significantly more active in the chin-up than in the pull-up1. The lower trapezius was significantly more active in the pull-up1. In 19 strength-trained men, peak and average activity of eight shoulder, arm and forearm muscles was similar across hand positions2. That study compared supinated, pronated, neutral and rope grips over whole repetitions2.

The same 19 men showed a difference in the middle trapezius, the middle part of that muscle2. Its peak and average activity were significantly greater with a pronated grip than with a neutral grip2.

A narrative review, a summary written without a set, checkable search method, looked at the latissimus dorsi9. It found broadly comparable EMG amplitude in that muscle across pull-up and chin-up grips9. That rested on four primary studies with about 84 participants in total9.

Handles, towels and grip width

Three studies changed what the hands held or how far apart they were1,10,11:

  • Rotating handles. In 21 men and 4 women, no differences in muscle activation were detected between a pull-up on rotating handles and the usual pull-up or chin-up1.
  • Suspension device and towel. In 15 resistance-trained men and women, latissimus dorsi, biceps brachii and posterior deltoid activity did not differ between these and traditional pull-ups10. Middle trapezius activity was significantly lower in the towel pull-up than in the traditional one10.
  • Grip width. In fourteen trained men, the one-repetition maximum (1RM, the heaviest load a person can lift once) was similar with two grips11. So were repetitions to failure11. One grip was shoulder width, and the other was freely chosen and about 20% wider on average11.

What kipping changes

In eleven athletes doing sets of five standard and five kipping pull-ups, the biceps brachii was less active in the kipping version3. The gap was about 27 percentage points of maximal voluntary isometric contraction3. Four trunk and hip muscles were significantly more active in the kipping version, by about 14 to 29 points3:

How the body adapts

Four studies measured pull-up performance before and after training12,13,14,15:

  • Men tested twice, 12 weeks apart. Of 52 men, 39 completed both tests12. After 12 weeks of training, pull-up 1RM rose by 3.4% and maximum repetitions with body mass rose by 15%12.
  • Inactive male students. Thirty were randomly assigned to three 8-week pull-up-based programmes that differed in their supplemental exercises13. Maximum pull-up repetitions, grip strength and dead-hang time improved significantly13. The group that added forearm training had the largest gain in repetitions, 222.5%13.
  • Climbers. A study randomly split 30 advanced to high-elite climbers into eccentric, isometric, plyometric and no-specific-training groups14. After 5 weeks, maximum pull-up strength had risen 2.2% to 5.0% in the three training groups, and the control group showed no change14. Eccentric work is done while a muscle lengthens, and isometric work while the joint does not move. Plyometric work stretches a muscle and then shortens it quickly.
  • College-age women. After a combined strength and aerobic conditioning programme aimed at the pull-up, upper body strength and fat-free mass (body weight that isn’t fat) increased significantly15. Fat mass and percentage of body fat decreased15.

A narrative review of latissimus dorsi EMG in pulling exercises, the pull-up among them, set a limit on EMG readings9. It states that no single-session EMG finding establishes that one exercise is the better one to train with over the long term9. It adds that long-term training studies measuring muscle size, strength or performance are absent from that literature9.

Progressive overload

A 2026 position stand describes progressive overload as the need to increase the stimulus placed on the muscle throughout a training programme16. The pull-up studies here each set the work in their own way5,13,14,17,18:

Who trained, and for how longWhat the programme didWhat was found
29 strength-trained men, 8 weeks (16 sessions) of body-mass pull-upsOne group ended each set at a 25% loss of repetition velocity; the other continued to a 50% loss5The 25% group improved significantly in each measured variable; the 50% group remained unchanged5
290 military conscripts, 9 weeks, with training volume matchedOne group did four 15-minute strength and four 15-minute endurance bouts a week; the other did one 60-minute session of each17Repetitions rose from 7.4 to 8.5 with short bouts and from 5.7 to 7.1 with long sessions17
The eccentric group in a 5-week, twice-weekly study on a hang board (a board with small edges to grip)The lowering phase alone: three 5-second repetitions at 95% of 1RM, then three body-weight upward jumps, for six sets14In 30 climbers, maximum pull-up strength improved in the three training groups, by 2.2% to 5.0%14
The groups of an 8-week study, twice weeklyAssisted pull-ups, inverted rows, reverse-grip pull-ups and negative pull-ups, each for three sets of as many repetitions as possible13In 30 inactive male students, repetitions improved significantly13
34 healthy, recreationally active male college students doing lat pull-downs under joint instability or on a stable set-up, 8 weeks, three times a weekFour sets of 12, with the load raised by 5% of 1RM every two weeks, from 65% to 80%18Pull-up repetitions rose from about 2.2 to 8.5 in the instability group and 5.8 in the stable group18

A negative pull-up, in that 8-week study, meant lowering under control from the top position13. An inverted row means pulling the body up toward a bar while hanging beneath it. A lat pull-down is a machine exercise in which a seated person pulls a bar down toward the chest.

The authors of the velocity-loss study concluded that repetitions past a 25% velocity loss did not bring additional gains5. They added that such repetitions can even blunt improvement in strength and endurance performance5.

Injuries reported with pull-ups

Surveys and a cohort in CrossFit training

Most of the injury evidence here comes from people doing CrossFit training6,19,20,21:

  • A systematic review of 25 studies covered 12,079 CrossFit practitioners19. The shoulder was the most injured area, at 26%19.
  • A survey of 187 people who trained in CrossFit gyms found 44 reporting a shoulder injury in the previous six months6. Respondents named gymnastics exercises as the primary cause of 25 of 46 injuries6. Those included the kipping pull-up for 5 and the butterfly pull-up for 26.
  • A survey of 386 participants found the shoulder was the area most often injured in gymnastic movements20. The authors defined that category to include pull-ups alongside muscle-ups, dips and push-ups20.
  • A 12-month prospective study of 109 athletes recorded 0.79 shoulder injuries per 1,000 training hours21. Gymnastics exercises (35%) and Olympic weightlifting (45%) were associated with shoulder injury21. The rotator cuff tendons were the structure most often injured21.

What movement studies suggested

Two suggestions come from authors who studied how eleven people moved4. From a study of eleven healthy men, the authors suggest the wide-grip pull-up may be associated with an increased shoulder injury risk4. Their reason was its significantly reduced range of scapular protraction and retraction4. They call this a concern for kipping pull-ups4.

From an observational study of 11 people who regularly do pull-ups, the authors suggest the reverse-grip pull-up potentially raises the risk of subacromial impingement4. That term means pinching of tissue in the space beneath the acromion, the bony point at the top of the shoulder. They place the risk in the hanging and starting phase, since this grip starts with the main shoulder joint turned far outward4. The shoulder impingement page covers that condition.

Single cases

Three case reports, each on a single patient, involve pull-ups or a related exercise22,23,24:

  • A 44-year-old woman had both shoulders dislocate forwards at the same time during chin-ups22. The authors wrote that, to their knowledge, this mechanism had not been reported before22. The shoulder dislocation page covers that injury.
  • A 30-year-old male CrossFit athlete tore his latissimus dorsi tendon during a bar muscle-up23. The authors describe that exercise as a combination of a pull-up and a dip23.
  • A male athlete had exertional rhabdomyolysis, a rapid breakdown of muscle tissue brought on by exercise24. After a period of detraining, he had done one session of 24 sets of push-ups and 24 sets of chin-ups24. He took no rest between sets24.

Connections

The muscles it works

The shoulder was the body area most commonly injured in gymnastic movements in a survey of 386 CrossFit participants20. That survey grouped pull-ups with the dip and the push-up20. The dead hang is the position one tested pull-up started from7.
