What an overhead press asks of the wrist, and what no study has countedEmerging evidence
In an overhead press the bar's weight comes down through the hands and forearms, first from the shoulders and then from arm's length overhead. With the bar low in the palm over the forearm bones and the wrist stacked over the elbow, the wrist holds a small bend; with the bar back in the fingers, behind the forearm, the wrist folds back and has to stop it bending further on every rep. The site's overhead press guide teaches the first and lists wrists bent back and elbows flared as a common mistake.
No study has measured the wrist in an overhead press: the only press study that included the wrist measured bench presses and cable exercises at 15% and 30% of body weight in 20 adults. In push-ups on a bent-back wrist, force travelled towards the back and the little-finger side of the wrist in 14 volunteers, and in 8 donated wrists a push-up position with the wrist bent back raised the pressure on the scaphoid's joint surface. That a bar sitting back in the fingers loads the wrist the same way, and is the usual cause of overhead press wrist pain, is our reading of these push-up and cadaver studies, not something measured. No study counts wrist pain from overhead pressing.

Grip width, dumbbells and machinesEmerging evidence
In 11 trained men doing seated barbell presses with narrow, medium and wide grips, narrower grips lifted more weight with more shoulder and elbow movement; wider grips pushed the bar outward more, and narrower grips inward. That study measured the bar, the shoulder and the elbow, not the wrist, so that a slightly narrower grip helps a wrist that folds back is our reading.
In 15 men, standing dumbbell presses lifted about 7% less than a standing barbell and about 10% less than seated dumbbells, with the most shoulder muscle activity. In 8 competitive bodybuilders, a shoulder press machine with a palms-in grip worked the shoulder muscles less than a barbell press, so a machine is a stepping stone rather than a full replacement. None of these studies measured the wrist.

Where it hurts, and what it often isEmerging evidence
A hand surgery review of pain in the middle of the back of the wrist in athletes describes the joint lining being pinched, with pain worse at full wrist extension and when loading the wrist bent back; hidden ganglia, to be considered in any athlete whose back-of-wrist pain gets worse bending back under load; and injuries of the scapholunate ligament, where a painful click or grinding when the wrist is loaded is a helpful clue, which athletes may notice in push-ups or the military press.
On the little-finger side, the ECU (extensor carpi ulnaris) tendon is a common source of pain with repeated loading, and the TFCC is the other common cause. On the thumb side, de Quervain's gives pain made worse by lifting the thumb, and UK hand surgeons say sport can aggravate it. Tingling in the thumb, index and middle fingers, often at night, is carpal tunnel syndrome, which the NHS links with frequently bending the wrist or gripping hard. A bar forcing the wrist back can break the scaphoid: two case reports describe it from a bench press, one found on a computed tomography (CT) scan 2 months later.

Who gets it, and what is rareEmerging evidence
Weight-training sports have low injury rates compared with team sports, and the wrist and hand are among the common injury sites; in weightlifting, the hands and fingers made up about 15% of injuries. In 270 CrossFit athletes, 20.4% had had a hand or wrist injury, about three-quarters of them at the wrist, and 72.8% were back to unmodified training within a month. CrossFit participants were more likely to be injured than traditional weightlifters in a 411-person survey, corrected in 2020 in ways that don't change its conclusions, and switching between prescribed and scaled loads went with injury. A review of CrossFit says injuries to the shoulder, elbow and wrist are more common than in traditional weight training. Of 321 adults who practise handstands, 56.7% reported long-lasting wrist pain.
In our reading, the people it usually bothers are people new to overhead pressing or adding load quickly, people who let the bar sit back in the fingers, flare the elbows or press with their thumbs off the bar, lifters who also load the wrist bent back in push-ups, front squats, cleans and handstands, and athletes doing high-rep presses and push presses. Serious causes are uncommon: a broken scaphoid after a missed lift or a fall, a stress injury of a wrist bone in a young high-level athlete, which early X-rays can miss, a joint infection or gout, an inflammatory arthritis, and, rarely, a lump that grows or is hard.

When a scan or test mattersEmerging evidence
Not at first for a gradual ache without warning signs: the NHS starts with home care and a GP if it isn't better after 2 weeks. After a missed lift or a fall with pain at the base of the thumb, an X-ray comes first, but a scaphoid fracture doesn't always show up on an X-ray right away, and the AAOS (American Academy of Orthopaedic Surgeons) describes a splint and a follow-up X-ray after 2 to 3 weeks, or an MRI (magnetic resonance imaging) scan. Back-of-wrist pain that keeps coming back when the wrist is loaded may need an ultrasound or MRI for a hidden ganglion or a ligament injury, while plain X-rays are typically normal in impingement; bone stress injuries of the wrist may not show on early X-rays either. Tingling that lasts needs a GP.

How it usually goesEmerging evidence
No study follows wrist pain from overhead pressing. The NHS expects wrist pain to improve with home care within 2 weeks, or to be checked, and a mild tendon injury to feel better within 2 to 3 weeks. A hand surgery review says most pinched joint lining settles within 2 to 3 months of rest, a splint and anti-inflammatory painkillers. A TFCC tear without an unstable forearm joint is slower: of 72 wrists treated without surgery, 30% had fully recovered at 6 months and 50% at a year. A broken wrist usually takes 6 to 12 weeks. Most powerlifters with an injury keep training with changes: only 16% of those injured stopped completely. No one can promise a date.
