Whether you are a competitive powerlifter, a passionate bodybuilder, or a fitness enthusiast who has just started a strength training routine, there is a high probability you will encounter elbow pain at some point in your journey. The elbow is a complex, heavily recruited joint that takes the brunt of the load during classic movements like the barbell bench press and bicep curls. Unfortunately, persistent elbow pain can quickly derail your progress and significantly affect your quality of life.
Below, we will deconstruct the biomechanical causes of lifting-related elbow pain, help you differentiate between tendon injuries and nerve entrapment, and provide you with actionable, evidence-based protocols to get you back to pain-free lifting.

The Anatomy of Lifting-Related Elbow Pain
To effectively treat elbow pain, we must first understand the structures involved. The elbow joint is the intersection of three bones: the humerus in the upper arm, and the radius and ulna in the forearm. At the lower end of the humerus, there are two distinct bony bumps known as epicondyles, which serve as crucial anchor points for the muscles and tendons of your forearm.
Depending on exactly where your pain is located, the biomechanical root cause of your injury will differ significantly:
Outer Elbow Pain: “Tennis Elbow” (Lateral Epicondylalgia)
Despite the common nickname, you do not need to be a tennis player to suffer from lateral epicondylitis. This condition affects the extensor tendons on the outside of your elbow, most notably the Extensor Carpi Radialis Brevis (ECRB).
- During the Bench Press: This injury frequently occurs if you bench press with excessive internal rotation of the shoulders. When your shoulders roll inward, your forearms pivot away from a neutral line. To keep your wrists straight and stabilize the heavy barbell, your common wrist extensors are forced into a constant isometric contraction, overloading the tendons and leading to tendinopathy.
- During Bicep Curls: If you allow your wrists to bend backward (extension) during a curl, the load heavily activates the extension tendons attached to the lateral epicondyle, causing micro-tears, inflammation, and pain on the outside of the elbow.
Inner Elbow Pain: “Golfer’s Elbow” (Medial Epicondylalgia)
Golfer’s elbow is a repetitive stress injury resulting from damage to the flexor muscles and tendons attached to the medial epicondyle on the inside of the elbow.
- During the Bench Press: Inner elbow pain is often caused by the exact opposite of outer elbow pain: excessive external shoulder rotation. When the shoulders rotate externally, the forearms again move out of alignment, forcing the wrist flexors to contract isometrically to stabilize the joint.
- During Bicep Curls: The most common culprit is gripping the bar or dumbbell far too tightly. Over-gripping hyper-activates the flexor tendon. Additionally, allowing your wrists to roll or curl forward during the movement places an immense strain on the inner elbow. This often happens when a lifter uses a weight that is too heavy for their forearm strength to handle properly.
Back of the Elbow Pain: Triceps Tendinopathy
If you feel a sharp ache at the back of your elbow—specifically where the triceps tendon attaches to the olecranon process—you are likely dealing with triceps tendinopathy.
- During the Bench Press: The primary cause is utilizing a grip that is too narrow. A close grip forces the elbows into a much deeper state of flexion, shifting the exercise from a chest-dominant movement to a triceps-dominant movement. The increased range of motion and load placed squarely on the triceps tendon can lead to rapid overloading and pain.
Tendonitis vs. Tendinopathy: Updating the Science
In modern sports medicine, the term “tendinitis” is heavily scrutinized. “Tendinitis” implies that the primary driver of the pain is acute inflammation. However, recent evidence suggests that chronic tendon pain often lacks an inflammatory component. Instead, the medical community now uses the term “tendinopathy”, which places tendon health on a continuum ranging from reactive, to dysrepair, to degenerative.
Tendinopathy typically occurs when you overload a tendon too quickly—doing too much, too fast, too soon. Because the tendon fails to adapt to the sudden increase in volume or intensity, the tissue begins to break down.
Crucially, this means that complete rest is rarely the right answer. While rest may temporarily decrease your pain, it also causes the tendon to decondition and weaken. When you return to the bench press or dumbbell rack, the weakened tendon is even more susceptible to reinjury. The true key to overcoming tendinopathy is modifying the activity to temporarily offload the tendon, and then gradually re-exposing it to the load to force a physical adaptation and strengthen the tissue.
Nerve Pain: When It’s Not Just a Tendon
Before assuming your elbow pain is tendon-related, it is critical to rule out nerve entrapment. Treating a nerve issue like a tendon issue can lead to prolonged suffering.
Cubital Tunnel Syndrome is a condition where the ulnar nerve becomes compressed as it travels through a narrow passageway behind the elbow. For gym-goers, frequent, heavy elbow bending (like deep bicep curls or bench pressing) or leaning heavily on the elbows for extended periods can inflame the tissues around this nerve.
How to tell the difference:
- Tendon Pain: Typically localized to the bony bumps on the inner or outer elbow, and worsens specifically when gripping, lifting, or performing repetitive wrist movements.
- Nerve Pain: Characterized by numbness, tingling, or a burning sensation that radiates from the inner elbow down the forearm, specifically into the ring and pinky fingers. You may also experience clumsiness or a noticeable weakness in your hand grip.
Practical Rehab and Prevention Strategies
If you are dealing with classic lifting-related elbow tendinopathy, you don’t necessarily have to abandon the gym. By implementing strategic biomechanical adjustments and intelligent programming, you can train around the pain while stimulating recovery.
Form and Grip Modifications
- Widen Your Bench Press Grip: If you are suffering from triceps tendinopathy (back of the elbow), moving your hands wider on the barbell is a highly effective immediate fix. A wider grip shifts the mechanical stress away from the triceps and onto the pectoral muscles, providing temporary offloading for the elbow.
- Correct Your Shoulder Rotation: If you have outer elbow pain, work on maintaining neutral shoulder rotation during pressing movements. If tightness prevents this, stretch the internal rotators (lats, pecs, anterior deltoid). Conversely, if you have inner elbow pain, stretch your external rotators (infraspinatus, teres minor) to prevent compensatory wrist flexion.
- Limit the Painful Range of Motion: If your elbow only hurts at the bottom of a bench press, switch to a “floor press” or “pin press” to shorten the range of motion. If it hurts at the top of the lift, perform a “soft lockout” where you stop the movement just shy of full elbow extension.
Utilize Tempo Training
Cranky tendons respond incredibly well to slow tempos. Try adopting a 3:0:3 tempo for your lifts (3 seconds lowering the weight, zero pause, 3 seconds pressing the weight back up). By slowing the movement down, you naturally have to decrease the weight on the bar. This provides a sufficient mechanical stimulus to the muscle while greatly reducing the absolute load and stress on your inflamed tendons.
The Power of Isometrics Isometric exercises—where the muscle contracts without changing length—have been shown to produce an analgesic (pain-reducing) effect on tendons. Exercises like alternating dumbbell bench presses (where one arm holds the weight steady at the top while the other presses) or simple shoulder taps can force the triceps and elbow stabilizers to work isometrically, helping to manage pain.
Targeted Eccentric and Concentric Loading
To rebuild the damaged tendon, progressive resistance is required. A highly effective, clinically-backed protocol for lateral epicondylitis (tennis elbow) involves using a light 1-to-2-pound dumbbell.
- 1. Sit with your forearm resting on a table, elbow flexed at 90 degrees, palm facing the floor.
- 2. Slowly lower the weight (eccentric), then slowly raise it back up (concentric) for up to 10 repetitions.
- 3. Next, fully straighten your elbow to 180 degrees so your arm is flat across the table, and repeat the same slow wrist extensions. The extended position stretches the extensor muscles further, generating optimal tension to build a healthy collagenous scar and heal the tendon. Note: Mild pain during these exercises is normal, but it should not be worse the following day.
Wear Elbow Sleeves
A pair of high-quality neoprene elbow sleeves can be an excellent addition to your gym bag. Sleeves provide valuable joint compression and stability, which helps alleviate stress during heavy lifts. Furthermore, they promote localized blood flow, keeping the joint warm and delivering oxygen-rich nutrients to the area to expedite recovery and reduce inflammation.
Advanced Clinical Interventions
If your elbow pain persists for 6 to 12 months despite resting, modifying your lifting technique, and engaging in physical therapy, it may be time to consult an osteopath. Osteopaths take a whole-body approach, looking at how your muscles, joints, and posture work together. Through manual adjustments and posturology, they can correct the underlying movement patterns and imbalances that led to the overuse injury in the first place.
Take Control of Your Joint Health
Elbow pain does not have to be a permanent barrier to your strength and fitness goals. By understanding the biomechanical causes behind your discomfort, adjusting your grip and tempo, utilizing compression gear, and following a structured strengthening protocol, you can actively rehabilitate your tendons while staying in the gym. Remember, pain is your body’s way of asking for a change in mechanics or volume—listen to it.
