Stretching your elbow really means stretching the muscles and tendons that cross the elbow joint, since the joint itself is moved by muscles in your forearm and upper arm. A few targeted stretches held for 15 to 30 seconds can improve flexibility, ease stiffness, and relieve common pain patterns like tennis elbow or golfer’s elbow. Here’s how to do each one safely and effectively.
Stretching the Outside of the Elbow
The muscles that run along the outer forearm (the wrist extensors) are the ones involved in tennis elbow and general lateral elbow tightness. To stretch them, hold your arm straight out in front of you with your elbow fully locked and your palm facing the floor. With your other hand, gently push down on the back of the affected hand until you feel a pull along the outside of your forearm near the elbow. Hold that position for 15 to 30 seconds, release, and repeat two to four times. That’s one session, and doing it twice a day is a good target.
This stretch is simple but the details matter. Keeping the elbow completely straight is what transfers the stretch to the muscles near the elbow rather than absorbing it at the wrist. If you bend your elbow even slightly, you lose most of the effect.
Stretching the Inside of the Elbow
The muscles on the inner forearm (the wrist flexors) connect at the bony bump on the inside of your elbow. Tightness or pain here is often called golfer’s elbow. To stretch this area, extend your arm straight in front of you with your palm facing up. Let your wrist relax so your hand drops back. Then use your other hand to gently pull the fingers and hand back toward your body until you feel a stretch along the inner forearm.
Hold for 30 to 45 seconds, rest for about 30 seconds, then repeat three times. Doing this twice a day is the standard recommendation. The longer hold time compared to the outer-elbow stretch reflects how the inner forearm tendons tend to be stubbornly tight, especially if you spend hours gripping a mouse, racket, or barbell.
Stretching the Back of the Elbow
Your triceps muscle runs from the shoulder down the back of the upper arm and attaches just below the elbow. When it’s tight, you may feel restriction when trying to fully bend your elbow or a pulling sensation at the back of the joint. The overhead triceps stretch is the most effective way to lengthen this muscle.
Raise one arm overhead, then bend at the elbow so your hand drops behind your head toward the opposite shoulder blade. Use your free hand to gently press the elbow further back until you feel a stretch along the back of your upper arm. This position puts the triceps at its greatest length. Hold for 15 to 30 seconds and repeat two to four times on each side.
Nerve Gliding for Elbow Tightness
Sometimes elbow tightness or tingling isn’t caused by muscle tension at all. It comes from the ulnar nerve, which runs through a narrow tunnel on the inner side of your elbow (the spot you hit when you bang your “funny bone”). When the nerve gets stuck or irritated, gentle gliding exercises can restore its mobility. These aren’t traditional stretches. They’re slow, controlled movements designed to help the nerve slide freely through its tunnel.
A good starting exercise: sit up straight and reach the affected arm out to the side at shoulder height, palm facing the floor. Flex your hand so your fingers point toward the ceiling. Then slowly bend your elbow to bring your hand toward your shoulder. Repeat five times at a slow, deliberate pace.
A slightly more advanced version adds a head tilt. Reach the arm out to the side with the elbow straight and palm facing up. Tilt your head away from that hand until you feel a gentle stretch. To increase the sensation, extend your fingers toward the floor. Return to the starting position and repeat five times. If you feel sharp pain, numbness, or increased tingling, back off. Nerve glides should produce a mild pulling sensation, not a jolt.
Aim to do nerve gliding exercises once a day, three to five times per week.
How Long to Hold and How Often
Research on static stretching consistently shows that the biggest gains in range of motion happen between 15 and 30 seconds of hold time. Holding longer than that doesn’t add much benefit for most people, and no additional muscle lengthening occurs after two to four repetitions per stretch. So doing three sets of 30-second holds is a practical sweet spot.
One exception: if you’re over 65, longer holds of around 60 seconds per stretch tend to produce better results. A study on older adults found that 60-second holds led to greater flexibility improvements compared to shorter durations.
The American College of Sports Medicine recommends stretching at least two to three days per week, preceded by some kind of light warm-up. For active elbow pain or stiffness, twice daily is more typical. Warming up the area first, even just by opening and closing your fist 20 times or running warm water over your forearm, makes the tissue more pliable.
When Stretching Can Do More Harm Than Good
Not all elbow stiffness should be stretched. After a fracture, dislocation, or surgery, aggressive stretching can damage healing tissue and even trigger abnormal bone growth within the muscle (a condition called heterotopic ossification). If your elbow is stiff after an injury, movement should be progressed gradually, starting with gentle active motion within a comfortable range before any assisted stretching.
Passive stretching, where someone else pushes your joint through its range, carries more risk at the elbow than at most other joints. The muscles around the elbow are especially reactive to forceful manipulation. If your stiffness developed after trauma, working with a physical therapist to define a safe range of motion is worth the visit. For general tightness, desk-related soreness, or mild overuse pain, the stretches above are safe to start on your own.
