Isometric Exercises Elbow Strengthening Exercises

If you have an injury to your upper extremity or elbow, you may benefit from the services of a physical therapist to help you regain normal range of motion (ROM) and strength of your arm. Elbow strengthening exercises may be an important component of your elbow injury rehabilitation.

Muscles of the Elbow

The bicep and tricep muscles are the large muscle groups that bend and straighten the elbow. The biceps are located on the front of the upper arm, and the triceps are located on the back.

As noted by the name, two heads (points of origin) form the biceps while three heads form the triceps. The biceps is also responsible for turning your forearm over so your palm is ​facing up.

Exercising these muscle groups not only increases arm strength but also helps people (especially older adults) perform everyday tasks and activities. Strong elbows and arms help lift you out of a chair and provide you the means to dress yourself, hoist objects onto a counter, and open and shut doors, cabinets, and drawers.

Isometric Elbow Strengthening

There are some excellent elbow- and arm-strengthening exercises that your PT may add to your exercise program. These include isometric exercises in which you contract muscles around the joint without making any movement.

There are three that are exceptionally well-suited to building strength and flexibility no matter your age. They can be done several times per week to help improve muscular function around your elbows.

Triceps Strengthening

The aim of this exercise is to use your own body weight to exert sustained pressure on the triceps muscles. You will need a chair with sturdy armrests able to bear your weight without placing you in an awkward position.

To do this exercise:

1. Sit in a straight-backed chair with armrests.
2. Put your feet flat on the floor.
3. Place your hands on the armrests and push up with your arms, lifting your bottom slightly off the chair.
4. Hold for a count of six.
5. Slowly lower yourself into the chair and relax.
6. Repeat this strengthening exercise 10 times.

This exercise works the triceps muscles located on the back of your upper arm. These muscles extend your arms and help you push things away from you. They are also muscles that are active when you are pushing yourself up from a chair with your arms.

Supination and Pronation

Supination and pronation is the action of turning your hand over to have your palm up or palm down. This simple exercise aims to increase and strengthening the rotational capacity of the elbow and forearm. For this supination and pronation exercise, you will need a washcloth or washcloth-sized piece of material.

To do this exercise:

1. Stand up straight, holding a washcloth in your hands.
2. Pretend to wring the cloth dry for six seconds.
3. Pause and repeat this motion 10 times.
4. Switch the direction in which your hands are wringing the cloth.
5. Repeat this 10 times.

Isometric Elbow Flexion

Elbow flexion is when your forearm moves toward your body by bending at the elbow. It is a motion meant to lift objects and also involves muscles of the upper arm, including the biceps. For the isometric elbow flexion exercise, you will need a chair and table.

To do this exercise:

1. Sit straight up with your hands under the table, palm-side up.
2. Lift your hands straight upward as if trying to lift the table.
3. Hold this position for six seconds.
4. Repeat this exercise 10 times.

Apply as much pressure as you can without causing pain. This exercise strengthens the biceps muscles located in the front of your upper arm. as well as strengthening muscles around the radius and ulna bones of your forearm.

A Word From Verywell

If you have an elbow injury, your physical therapist can assess your condition and prescribe exercises to improve your elbow mobility and strength. These isometric strengthening exercises may be one component of a well-balanced therapeutic rehab program.

Progression from these exercises to more challenging ones can be done by adding a resistance band to your workout or by using dumbbells while performing the exercises.

By working with a PT and being vigilant about your home exercise program, you can get back to your normal functional mobility quickly and safely.
