Forearms are often an overlooked muscle group; as such, we have put together the Top 10 Forearm muscle exercises below alongside forearm anatomy, stretches and top injuries.
The forearm may be the overlooked brother of the upper arm, yet they are essential for many daily life activities.
Forearm bones
The forearm consists of two bones, The Radius on the thumb side of your forearm and the Ulna on the little finger side of your forearm.
The Radius is connected to the Humerus (upper arm bone) at the elbow.
The Ulna makes up most forearm bones, with its length from below your elbow down to just above where it meets your wrist. It’s shaped a bit like a banana and is curved towards your thumb side.
The ulna bone has two knobby protrusions—the Olecranon process (located at the pointy end of the elbow) and the Coronoid process (bump on the front of the Ulna). The Ulna is connected to both the Humerus and Radius in two different places in your forearm.
Forearm muscles
There are six muscles in the forearm, and they all work together to move your hand, wrist and fingers. They can be split into three main groups.
If you need further information head on over to this informative article
#1 Flexor muscles
these muscles pull your hand and fingers towards your body. The Flexor muscles are located on the front of the forearm. The flexor muscles are :
The Flexor digitorum profundus muscle flexes the fingers at their middle and distal phalanges.
The Flexor carpi ulnaris muscle flexes the wrist, adducting it towards the Ulna. The Palmaris longus-elongate muscle runs from the medial (inner) epicondyle of
#2 Extensor muscles
these muscles pull your hand and fingers away from your body. The Extensor muscles are located on the back of the forearm. These muscles pull your hand and fingers away from your body. The Extensor muscles are :
The Extensor digitorum muscle extends the fingers at their proximal and middle phalanges away from the hand.
The Extensor carpi radialis brevis muscle extends the wrist, abducting it from the Radius.
The Extensor carpi radialis longus & brevis muscles extend the wrist, abducting it from the Radius. The Extensor pollicis longus muscle extends the thumb at its proximal phalanx ( joint just before the thumbnail )
#3 Forearm Rotation muscles
Internal rotators turn your arm so it faces inwards towards your body. External rotator turns Forearms, so arm faces outwards away from the body. Forearm rotation muscles are located on the sides of the Forearms and are:
The Supinator muscle is an internal rotator and abducts the hand (taking it away from the body).
The Pronator teres muscle, which is a pronator (turns the forearm over, so the palm faces down) and flexes the elbow.
Forearm range of motion (ROM)
Your forearm has a good range of motion because it’s not a weight-bearing bone. You can move your forearm in all directions – up, down, forward, backward, and twist it from side to side because it has two joints. The forearm is also able to rotate inwards and outwards. The forearm is linked to the fingers, wrist, and elbow joints.
The elbow range of motion(ROM) can be increased by stretching Forearm muscles. Forearm stretches can be done using a rope or towel, and you can use both arms to increase the stretch.
Forearm stretches help improve Forearms flexibility by improving Forearm range of motion. Forearms stretches are used in the treatment and prevention of forearm injures.
Forearms stretching also helps to improve grip strength because it strengthens Forearm muscles that control finger movement and wrist function.
Forearm range of motion tests, Forearms should be able to move freely and without pain.
The wrist flexor ROM test assesses the ability to flex the forearm and bring your hand closer to your elbow by bending your forearm.
The wrist extensor ROM test assesses the ability to extend or straighten out your forearm and bring your hand backwards by bending your forearm.
The elbow flexor ROM test is used to check how far you can bring your forearm close to your body by bending it from the elbow joint.
Forearm Stretches
#1 – Forearm stretch #
- Lie on your back with hands facing down and Forearm on the floor
- Forearms can be stretched by raising hands towards the head while palms rest on the floor.
- Forearms are held for 20-30 seconds, returning to the starting position.
- Forearms stretching is done two times a day of three sets each.
#2 – Forearm stretch
- Forearm stretches when seated, one arm at a time.
- Place hand and arm on the opposite knee, then lean towards the extended hand.
- The forearm is held for 20-30 seconds, returning to the starting position.
#3 – Forearm stretch
- Sit on the floor with legs crossed, holding one wrist with the other hand.
- Use your body weight to pull your hand closer to you until you feel a stretch in your forearm.
- Hold this position for 20-30 seconds, then release and switch arms.
Wrist Stretches
Wrist stretches will aid forearm flexibility and its range of motion at this joint.
Therefore we have included three examples of wrist stretches below.
#1 – Wrist stretch
- Place one hand behind you; fingers pointed down.
- Use the other hand to gently pull your fingers back until you feel a stretch in your wrist.
- Hold for 20-30 seconds, then release
#2 – Wrist stretch
- Place your hand on a table; fingers pointed down.
- Use the other hand to gently push your fingers up until you feel a stretch in your wrist.
- Hold for 20-30seconds and release.
#3 – Wrist stretch
Forearm stretches and Wrist stretches can also be done on a wall,
- Place your forearm and wrist against the wall,
- then push it gently but firmly until you feel a stretch.
- Hold for 20-30 seconds, then release.
- Repeat three times each day
Injuries to the Forearms
Several injuries can occur to Forearms muscles, tendons or ligaments. These include:
Strains:
A strain is an injury to the muscle. It is caused by overuse or forceful contraction of the Forearm muscles. Symptoms include pain, swelling and bruising.
Tendinitis:
Tendinitis is an injury to the tendon. The tendon becomes inflamed and irritated. It is caused by overuse, incorrect use or misuse of Forearms muscles, or sudden trauma such as a fall.
Bursitis:
Bursitis is an inflammation of the bursa. The bursa is a small, fluid-filled sac that cushions and lubricates the Forearms muscles and tendons as they move over bones.
Ligament sprain:
A ligament sprain is an injury to one or more ligaments in the Forearms. This can be caused by a sudden injury such as falling or overusing Forearm muscles repeatedly in sports.
Forearm fracture:
Forearm fractures are common injuries that often occur when someone falls onto an outstretched hand or forearm. Forearm fractures may also occur after a direct blow to the Forearms, such as playing contact sports.
The Top 10 Forearm muscle exercises
These Top 10 forearm exercises are those that can help improve forearm strength, range of motion and flexibility.
#1 – Forearm dumbbell curls
Target muscles: Forearm flexors
How to:
- Sit with a weight in each hand, palms facing forward.
- Curl the weights up towards your shoulder, keeping your elbows close to your sides.

How to:
- Hold a weight in one hand, palm facing down.
- Bend your Forearms up so that they’re at right angles to the Forearms.
- Then extend your forearm out until it’s straight and level with the floor.
- Pause, then slowly lower them back to the starting position.
- Repeat 12-15 times for three sets
Tip: Use a lightweight
#3 – Hammer curls
Target muscles: Forearm flexors
How to:
- Sit with a weight in each hand. Keep your Forearms by your sides.
