What dips ask of the elbow, and what no study has measuredEmerging evidence
On bars you hold your whole weight on straight arms and lower by bending your elbows; the triceps controls the lowering and straightens the elbow to press you back up, with the chest and the front of the shoulder. In 13 experienced men, bar and ring dips drew more triceps activity than bench dips, and bench dips bent the elbow less while taking the shoulder to 101% of each man's measured maximum backward range, against 88% for bar dips and 69% for ring dips. In 15 experienced men dipping to failure, the elbows bent to about 115 degrees at the bottom, and tiring didn't make them go deeper. In a study of 15 women funded by the American Council on Exercise (ACE), chair dips drew 87% of the triceps activity of the diamond push-up, the top exercise.
No study has measured the forces at the elbow during any dip, and none counts what causes elbow pain in dips; the dip researchers' worry is the front of the shoulder, not the elbow. So the map on this page comes from these lab studies, a gym survey, case reports and series of triceps tears, nerve studies and health-service pages.

Who gets itEmerging evidence
In an online survey of 1,387 recreational gym users, 136 of the 392 who did bodyweight dips (35%) linked them to training pain, and 59 had stopped them because of it; for bench dips it was 64 of 301 (21%), and for machine dips 36 of 386 (9%). The elbow was the fourth commonest pain site overall, but the survey didn't say which exercise hurt which area, and it is a self-selected sample, so it can't give a risk per session.
Among competitive lifters, the elbow made up 11% of injuries in 101 Oceania powerlifters and 8.0% of powerlifting injuries (elbow and upper arm) in pooled surveys, and upper limb injuries, the elbow included, were more common in powerlifters over 40. Our reading of who it bothers: people adding dips, weighted dips or dip challenges quickly, people who dip deep or bounce at the bottom, and people already doing close-grip presses, skull crushers or push-ups the same week.

The triceps tendon, from ache to tearEmerging evidence
NHS referral guidance describes triceps tendon pain as "well localised pain at the triceps insertion on resisted elbow extension", and says it "occurs occasionally in weightlifters". Strength is usually kept.
A tear is different and rare: under 1% of upper limb tendon ruptures. The American Academy of Orthopaedic Surgeons (AAOS) says most come from pushing a heavy load, with sudden sharp pain and swelling at the back of the elbow. In repaired athletes, weightlifting caused 40.7% of tears, mainly while lowering in the bench or overhead press, and in professional players the usual story was a load on a triceps working to control the lowering. Anabolic steroid users had about 9 times the rate of tendon tears of other bodybuilders, and steroid injections near the tendon preceded several tears in case reports.

The inner elbow and the nerveEmerging evidence
In 26 healthy people, the ulnar nerve slid partly or fully out of its groove in 21% of elbows at a right angle and 54% at full bend. On ultrasound it slipped in 76% of 492 elbows in college athletes, mostly without symptoms, so a flick alone isn't damage. A snapping triceps is rare and almost always comes with a slipping nerve (58 of 64 cases).
The British Society for Surgery of the Hand says cubital tunnel syndrome usually starts with numbness or tingling in the little and ring fingers, often on and off, brought on by leaning on the elbow or holding it bent. Deep dips hold the elbow well bent under load, which fits tingling at the bottom of the dip (our reading).

When a scan or test mattersEmerging evidence
Not for ordinary overuse pain: NHS referral guidance manages triceps tendon pain without imaging at first. A suspected tear needs an examination and usually imaging: an X-ray can show a fleck of bone pulled off with the tendon, and ultrasound or magnetic resonance imaging (MRI) shows how much is torn.
Weakness can be subtle, because only about 20% of complete tears lose straightening altogether, and a 53-year-old bodybuilder's full tear was treated as bursitis for 5 weeks. Tingling that keeps coming back may need nerve tests, and a hot, swollen bursa may need checking for infection. A slipping nerve shows on ultrasound in most athletes' elbows, so a scan finding on its own isn't the diagnosis.

How it usually goesEmerging evidence
No study follows elbow pain from dips. NHS referral guidance says triceps tendon pain "Can improve within weeks to months depending on contributing factors", and NHS inform says new elbow pain should begin to settle within 6 weeks. Partial triceps tears often heal without surgery (6 of 10 in professional players). After a repair, 93% of athletes returned to sport at an average of 5.2 months, and 95% of 22 strength athletes returned. The NHS says bursitis should go away in a few weeks. No one can promise a date.
