Tennis elbow is a common overuse injury that causes pain on the outside of the elbow. This condition is characterized by damage and micro-tears to the tendons of the forearm muscles that attach to the lateral epicondyle. When training the biceps with this injury, the primary goal is to maintain strength without aggravating the stressed tendons. This requires focusing on modifications that reduce strain on the wrist extensor muscles responsible for the pain.
How Bicep Movements Affect Tennis Elbow
The pain associated with tennis elbow originates from the common extensor tendon, which attaches to the lateral epicondyle. Standard bicep exercises often involve two movements that place stress on this injured area: gripping and forearm rotation.
Gripping a weight requires the wrist extensor muscles to contract to stabilize the wrist. When these muscles are damaged, this stabilization effort pulls on the inflamed tendon attachment point, causing pain. Furthermore, a standard bicep curl requires the forearm to supinate, or turn the palm upward. This movement also engages the wrist extensors and increases tension at the lateral epicondyle. Heavy or repetitive loading during these motions risks exacerbating the micro-tears in the tendon.
Recommended Bicep Exercises and Grip Modifications
The most effective modification is to eliminate or minimize supination and reduce the required grip strength. Using a neutral grip, where the palms face each other, is the preferred starting point for most exercises, as this significantly reduces the strain on the wrist extensors. This neutral position is naturally achieved with Hammer Curls using dumbbells.
Hammer Curls keep the wrist in a relaxed, thumbs-up position throughout the movement, directly avoiding the supination that irritates the lateral epicondyle. This exercise also shifts some of the load to the brachialis and brachioradialis muscles, which are less involved in the injury mechanism. Focus on controlling the lowering phase, known as the eccentric contraction, since controlled loading is beneficial for tendon health.
Cable Curls with a Rope Attachment are another beneficial option because they allow for a neutral grip and provide constant tension, which can be less jarring than free weights. The rope attachment also permits the hands to move independently, allowing the user to find the most comfortable wrist angle throughout the curl.
Machines like the Dumbbell Preacher Curl can be helpful, as resting the arm on the pad removes the need for the forearm muscles to stabilize the shoulder and elbow joint. This reduced stabilization requirement allows the injured wrist extensors to relax during the lift.
Regardless of the exercise chosen, avoid the tendency to fully turn the palm upward (supinate) at the top of the movement. Instead, maintain the neutral or slightly pronated grip throughout the entire range of motion. It is also wise to temporarily reduce the overall range of motion, stopping just before the point where the elbow is fully extended, to prevent excessive stretch on the forearm muscles.
Crucial Safety and Recovery Protocols
Load management is important when training with an overuse injury like tennis elbow. This means a significant reduction in the weight used for all bicep exercises, often by 50% or more. Focus instead on higher repetition ranges, such as 15 to 20 repetitions. The goal is to stimulate the muscle without overloading the compromised tendon.
You must learn to distinguish between muscle fatigue and tendon pain. A dull, burning sensation in the muscle being worked is acceptable. However, any sharp, shooting, or intense pain at the outside of the elbow is a signal to stop the exercise immediately. Continuing to push through sharp pain will only worsen the tendon injury and delay recovery.
Allowing sufficient rest between training sessions is necessary for tendon repair, so avoid training the affected arm on consecutive days. If the pain persists despite activity modification or begins to interfere with daily activities like lifting a coffee cup, consult a physical therapist or doctor. They can assess the injury and prescribe a specific rehabilitation program that involves targeted eccentric strengthening of the wrist extensors.
