Elbow clicking during weight training usually comes from soft tissue sliding over bone rather than from joint damage, and in most cases you can reduce or eliminate it by modifying your exercise technique, limiting how deeply you bend the elbow under load, and addressing any muscular imbalances around the joint. The sound itself has a few distinct anatomical causes, though, and not all of them respond to the same fixes. Understanding which structure is producing the click tells you which adjustments are worth trying and when the noise warrants a trip to a doctor.
What Actually Causes the Click
The elbow is a hinge joint, but it has several soft-tissue structures that can catch, snap, or slide during movement. Most clicking falls into one of two categories depending on which side of the elbow it comes from.
Clicking on the inner (medial) side is usually caused by the ulnar nerve or a portion of the triceps tendon slipping over the bony bump at the inside of the elbow, known as the medial epicondyle. During flexion, the ulnar nerve can slide out of its groove, relocate in front of or toward the inside of the epicondyle, and then snap back into place when you straighten the arm.1PubMed. Ulnar nerve subluxation and dislocation: a review of the literature This back-and-forth is what produces the audible or palpable snap. The medial head of the triceps can do something similar, flicking over the epicondyle when you bend past a certain angle.2PubMed Central. Snapping elbow-A guide to diagnosis and treatment
Clicking on the outer (lateral) side has different origins. It often traces to a synovial plica, which is a fold of joint lining tissue that can catch between the bones during motion. Patients with this issue typically report clicking or snapping accompanied by lateral elbow pain, sometimes with a catching or locking sensation, especially at the extremes of the range of motion.3PubMed Central. Synovial plica of the elbow and its clinical relevance Less commonly, a torn annular ligament or a small remnant of developmental tissue near the radial head can produce similar symptoms.2PubMed Central. Snapping elbow-A guide to diagnosis and treatment
The practical takeaway: if your click is on the inside and gets louder or more noticeable as you bend deeper, you are likely dealing with nerve or triceps subluxation. If it is on the outside and comes with a catching feeling, a plica or ligament issue is more probable. These two scenarios call for somewhat different management strategies.
Which Lifts Are Most Likely to Trigger It
Not every exercise provokes elbow clicking equally. The snapping tends to be most prominent during movements that load the triceps eccentrically, meaning the muscle is lengthening under tension while controlling the weight. Push-ups, rowing, and overhead pressing can all bring it on, but the lifts most commonly associated with medial-side snapping are curls and skull crushers, both of which take the elbow through a deep flexion arc while the triceps or biceps are under significant load.4PubMed Central. Snapping triceps syndrome: a review of the literature and proposed operative treatment algorithm
Bench pressing deserves its own mention. A wider-than-shoulder-width grip increases the forces acting on the elbow in multiple directions, particularly the side-to-side (valgus-varus) forces and the rotational moment through the forearm. Narrowing your grip to roughly shoulder width has been shown to reduce these loads significantly.5Biomedical Engineering: Applications, Basis and Communications. Elbow load during different types of bench-press exercise So if you are experiencing clicking during bench press, one of the simplest experiments is to bring your hands in closer and see whether the noise diminishes.
Grip width also changes where in the lift the elbow experiences the most mechanical disadvantage. Research on the “sticking region” of the bench press found that varying grip width shifts the joint angles at which force production is poorest, partly because the moment arm of the barbell about the elbow changes.6PubMed. The effects of grip width on sticking region in bench press In plain terms, there is no universally safe angle, but a shoulder-width grip tends to distribute stress more evenly across the joint.
Practical Technique Adjustments
The single most effective modification for medial-side snapping is limiting your elbow flexion to about 90 degrees during the exercises that provoke it. Clinical recommendations for snapping triceps syndrome specifically advise avoiding flexion beyond that angle while continuing to train with slight modifications.4PubMed Central. Snapping triceps syndrome: a review of the literature and proposed operative treatment algorithm For skull crushers, that means stopping the descent earlier. For curls, it means not squeezing the weight all the way to your shoulder. For triceps dips, it means cutting depth. You lose a small portion of the range of motion, but you keep the nerve or tendon from crossing the epicondyle, which is the event that produces the snap.
Other adjustments worth trying:
- Grip orientation: Switching from a straight barbell to a neutral-grip (palms facing each other) handle for presses and extensions changes how the forearm rotates, which can alter whether the ulnar nerve catches on the epicondyle. Many lifters find that an EZ-curl bar or a Swiss bar eliminates clicking that a straight bar produces.
- Tempo control: Slowing down the eccentric phase gives the soft tissue more time to track smoothly rather than snapping abruptly. This won’t cure an anatomical subluxation, but it often quiets mild clicking enough that you stop noticing it.
- Load management: If clicking only appears above a certain weight, you are likely overwhelming the joint’s ability to stabilize under load. Backing off to a weight where the movement is click-free and building back up slowly lets the stabilizing muscles catch up.
These changes are not permanent sacrifices. For many people, the clicking diminishes over weeks of modified training as the tissues around the joint adapt. The goal is to avoid the repetitive traumatization that, over time, can irritate the ulnar nerve and produce chronic nerve pain.7PubMed Central.

The Warm-Up Question
You will hear advice everywhere that a proper warm-up prevents joint clicking. It is reasonable to assume that warming up the joint with light movements and gradually increasing load would help, and doing so is certainly not going to hurt you. But the evidence that a structured warm-up specifically reduces elbow clicking or elbow overuse injury severity is weaker than most people think. A randomized trial of a sport-specific warm-up program in disc golf players, a sport that puts repetitive stress on the elbow, found no significant difference in elbow injury severity between the warm-up group and the control group over six months.4PubMed Central. Snapping triceps syndrome: a review of the literature and proposed operative treatment algorithm That does not mean warming up is useless, but it suggests the clicking problem is more about anatomy and technique than about tissue temperature. A few sets of light curls before your working sets are a good habit, but they are unlikely to silence a joint that clicks because of a nerve sliding over bone.
Can Strengthening the Forearms Fix It?
A popular piece of gym wisdom holds that clicking and instability in the elbow can be fixed by strengthening the forearm flexors, which act as dynamic stabilizers of the joint. This makes intuitive sense, and there is no downside to developing stronger forearms. However, research on elbow valgus instability in throwing athletes found no association between forearm flexor muscle strength and the degree of instability.8PubMed. Relationship between the elbow joint valgus instability and forearm flexor muscle strength in high school pitchers with and without symptom The clicking in lifters is not identical to the instability in pitchers, but the finding is a useful reality check: the problem is often structural rather than muscular. Forearm curls and grip work are good for your training in general, but they may not be the solution to a clicking elbow specifically.
That said, physical therapy aimed at changing the line of pull of the triceps is part of the recognized conservative treatment for snapping triceps syndrome.4PubMed Central. Snapping triceps syndrome: a review of the literature and proposed operative treatment algorithm This is a different kind of strengthening, more targeted than generic forearm work. A physical therapist can assess whether the medial head of your triceps is hypertrophied or positioned in a way that predisposes it to snapping, and can prescribe exercises to address that. If you’ve been doing all the technique adjustments and the clicking persists, this is a worthwhile next step before considering anything more invasive.
When Clicking Becomes a Medical Problem
Painless clicking that does not change over time and does not come with tingling, numbness, or weakness is annoying but generally not dangerous. The situations that warrant a medical evaluation are more specific:
- Tingling or numbness in the ring and little fingers: This suggests the ulnar nerve is being irritated by repeated subluxation. Left unaddressed, repetitive nerve trauma can lead to focal neuritis and chronic nerve pain.7PubMed Central. The Snapping Elbow Syndrome as a Reason for Chronic Elbow Neuralgia in a Tennis Player – MR, US and Sonoelastography Evaluation
- Catching or locking: A joint that intermittently gets stuck mid-motion suggests tissue is interposing itself between the joint surfaces, which often points to a synovial plica or loose body that may need intervention.3PubMed Central. Synovial plica of the elbow and its clinical relevance
- Pain that worsens progressively: Clicking that was painless for months but is now painful signals that the repetitive mechanical insult is causing tissue damage.
- Weakness in grip or wrist extension: This can indicate more advanced nerve involvement.
If you do see a doctor, the most informative imaging for a clicking elbow is dynamic ultrasound rather than a static MRI. Standard imaging takes a snapshot of the joint at rest, which can miss a nerve or tendon that only misbehaves during movement. Dynamic ultrasound captures the joint in real time as the examiner flexes and extends your elbow, making it possible to see exactly what is snapping and where.9PubMed Central. Role of dynamic ultrasound in assessment of the snapping elbow and distal biceps tendon injury It is also noninvasive, requires no contrast injection, and can visualize both extra-articular and intra-articular causes of the snapping.10JSES Reviews, Reports, and Techniques. Dynamic sonographic diagnosis of snapping elbow associated with congenital radioulnar synostosis If your physician orders only a standard MRI and it comes back clean, it is worth asking about a dynamic ultrasound before concluding nothing is wrong.
Surgical Options If Conservative Measures Fail
Most lifters will never need surgery for elbow clicking. But for those who have tried activity modification, range-of-motion limits, and physical therapy without relief, surgical options exist and tend to have good outcomes. The specific procedure depends on what is causing the snap.
For ulnar nerve subluxation, the standard surgery is anterior transposition of the nerve, which repositions it to the front of the epicondyle so it can no longer flick back and forth. For a snapping medial triceps, the dislocating segment of the muscle can be resected or centralized. In cases where both the nerve and the triceps are involved, both procedures can be combined. One case report of bilateral snapping triceps syndrome found that staged anterior transposition combined with partial resection of the snapping triceps portion resolved the patient’s pain and snapping immediately, with a full return to normal activity within three months.11PubMed Central. Bilateral snapping triceps syndrome: A case report
When the snapping is caused by an underlying bony deformity, such as a varus (inward) angulation of the humerus, a corrective osteotomy may be required to realign the bone. This normalizes the soft-tissue mechanics and can eliminate both the triceps snapping and the ulnar nerve dislocation without needing a separate soft-tissue procedure. If snapping persists after the bony correction, additional soft-tissue surgery can be added.4PubMed Central. Snapping triceps syndrome: a review of the literature and proposed operative treatment algorithm These are not minor procedures, and they are reserved for people whose quality of life or ability to train is significantly compromised after exhausting conservative options.
Do Collagen Supplements Help?
Collagen peptide supplements have become a fixture in the lifting community, marketed for joint health and recovery. The evidence for their effect on joint pain is real but modest. A systematic review of collagen supplementation studies found small beneficial effects on joint pain during activity, with one study reporting a small-to-moderate effect on pain during walking and another showing improved range of motion and longer pain-free exercise duration with type II collagen.12PubMed Central. The effects of collagen peptide supplementation on body composition, collagen synthesis, and recovery from joint injury and exercise: a systematic review These studies were mostly in people with existing joint disease like arthralgia or osteoarthritis, not healthy lifters with mechanical clicking. If your elbow clicks because the ulnar nerve is sliding over bone, collagen supplements are not going to change the anatomy that produces the snap. If your clicking comes with diffuse joint discomfort and you want to try something low-risk, collagen may modestly help the pain component, but do not expect it to silence a mechanically produced click.
Younger Lifters and Growing Joints
Adolescents and teenagers who lift weights and experience elbow clicking deserve a separate mention because their joints are still developing. The most concerning elbow condition in this age group is osteochondritis dissecans of the capitellum, a disorder of the cartilage and underlying bone on the outer side of the elbow that develops from repetitive stress. Teenagers engaged in sports that load the elbow repeatedly are at particular risk.13PubMed Central. Osteochondritis dissecans of the capitellum in adolescents
In young lifters, clicking and lateral elbow pain should not be dismissed as normal joint noise. Stable lesions can be treated with rest and activity modification, but unstable lesions or those that do not respond to conservative measures require surgery.13PubMed Central. Osteochondritis dissecans of the capitellum in adolescents The key is early detection. A teenager whose elbow clicks during curls and who also has lateral pain, reduced range of motion, or a locking sensation should see a sports medicine physician rather than just switching exercises. For adults whose growth plates have long since closed, this particular condition is not a concern, and the management principles described earlier in this article apply.
The Psychology of Joint Noise
There is one more factor worth addressing, though it is easy to overlook: your relationship with the sound itself. Research on pain-related fear and movement has consistently shown that anxiety about a joint sensation can change how you move, leading to compensatory patterns that may create new problems elsewhere. If every click makes you flinch, stiffen your shoulder, or cut a rep short in an uncontrolled way, the avoidance behavior can stress your shoulder and wrist more than the click is stressing your elbow. Some lifters spiral into progressively more cautious movement patterns until they’ve eliminated half their exercises from an unfounded fear that the joint is deteriorating.
This is not to dismiss genuine symptoms. Tingling, progressive pain, and locking all warrant investigation. But if a thorough evaluation shows nothing structurally wrong and the click is painless, accepting the noise and training through it with good technique is often the right call. Joints make sounds. Not every sound is a warning sign, and a quiet elbow is not inherently healthier than one that clicks. The distinction between a problem to solve and a quirk to ignore is whether the clicking comes with any of the red-flag symptoms outlined earlier. If it does not, the best approach may simply be to stop listening for it.
