Hammer curls are a popular exercise for building upper arm strength and increasing curling strength. They are an isolation movement, targeting the bicep muscle, specifically the long head of the bicep. Hammer curls also work the elbow flexors, which are made up of the biceps brachii, brachioradialis, and brachialis muscles. These muscles are responsible for bending the elbow and bringing the hand towards the shoulder. The exercise can be performed with dumbbells, with the palms facing each other, and is a great way to build strength and increase muscle mass in the arms.

What You'll Learn
Hammer curls work the biceps brachii
Hammer curls are a great exercise to build upper arm strength and increase curling strength. They are a variation of the traditional bicep curl and are performed with the hands facing each other. This exercise is particularly good for targeting the short head of the biceps brachii, which is the most superficial of the flexors and the most visible mass on the front of the arm.
The biceps brachii is one of the elbow flexors, which are the muscles that bring your hand to your shoulder by bending your elbow. The biceps brachii crosses both the elbow and shoulder joints, allowing it to create motion for both. Specifically, it flexes the elbow and assists in flexion of the shoulder. The biceps brachii has two heads that originate at the shoulder joint and a bony prominence on the front of the shoulder blade, inserting on the radius bone just below the elbow.
Hammer curls are isolation movements, which means they target just the bicep muscle. While the inclusion of the brachialis and brachioradialis muscles is necessary, nearly all the emphasis is on the bicep. The bicep itself has two heads that adhere to the scapula and connect at a common insertion point. Its basic function is to move your arms forward, upward, and to the sides. It also stabilizes the shoulder when carrying objects or supporting weight and assists with pulling and curling motions.
To perform a hammer curl, stand with your feet hip-width apart, holding a pair of dumbbells with a neutral grip (palms facing each other). Squeeze your shoulder blades, abs, and glutes to create full-body tension. Curl the dumbbell up, moving only at the elbow joint, and keep your upper arms still and perpendicular to the floor. Squeeze your biceps at the top of the movement, and then slowly lower the weight back to the starting position.

Hammer curls target the brachioradialis
Hammer curls are a great exercise to add to your fitness routine. They are a simple exercise, but proper form is important. They are similar to bicep curls but are performed with the palms facing each other. This neutral grip allows for a greater focus on the short head of the bicep. Hammer curls target the elbow flexors, which are made up of the biceps brachii, brachioradialis, and brachialis muscles. These muscles are responsible for bending the elbow.
The brachioradialis muscle originates on the upper arm, near the elbow joint, and terminates on the forearm, just before the wrist. This muscle helps to flex the elbow and gives visible mass to the front of the forearm. It is the most prominent muscle in the front of the forearm and is responsible for the forearm's visible mass.
Hammer curls are a great way to build strength in the brachioradialis muscle. They can be performed with dumbbells, by holding the weights at your sides with your palms facing each other. Keeping your back straight and elbows against your sides, bend your elbows to bring the dumbbells up towards your shoulders. Pause, and then slowly lower the weights back down to the starting position.
By performing hammer curls, you can effectively target the brachioradialis muscle and increase strength and size in your forearms. This exercise is a great addition to any fitness routine, helping to improve overall arm strength and appearance.

Hammer curls build the brachialis
Hammer curls are a great exercise to add to your fitness routine to build your upper arms and increase your curling strength. They are a good alternative to the traditional bicep curl if you want to target your biceps from a different angle or are looking for more variety in your workout routine.
Hammer curls work the elbow flexors, which are the muscles that bring your hand to your shoulder by bending your elbow. The elbow flexors are made up of three muscles: the biceps brachii, brachioradialis, and brachialis. The biceps brachii is the most superficial of the flexors and is the most visible mass on the front of the arm. The brachioradialis originates on the upper arm, closer to the elbow joint, and terminates on the forearm, just before the wrist. This muscle helps to flex the elbow and gives visible mass to the front of the forearm.
The third muscle targeted by hammer curls is the brachialis, which is the focus of this exercise. The brachialis muscle helps to make your arms look bigger and stronger. By training with heavier loads, you can build bigger muscles and increase the overall girth of your arms. The hammer curl grip, with palms facing each other, allows you to lift heavier weight and focus more on the brachialis muscle.
To perform hammer curls effectively, hold a pair of dumbbells with a neutral grip, palms facing each other. Stand with your feet hip-width apart and squeeze your shoulder blades, abs, and glutes to create full-body tension. Curl the dumbbells up, moving only at the elbow joint, and keep your upper arms still and perpendicular to the floor. Squeeze your biceps at the top of the movement and slowly lower the weight back down to the starting position.
By adding hammer curls to your workout routine, you can effectively target the brachialis muscle, leading to increased arm strength and a more defined physical appearance.

Hammer curls strengthen the elbow flexors
Hammer curls are an excellent exercise to build upper arm strength and increase curling strength. They are a great alternative to traditional bicep curls, targeting the bicep muscle and the long head of the bicep in particular. Hammer curls also engage the brachialis and brachioradialis muscles, which are important for elbow flexion.
The elbow flexors are a group of muscles that allow the hand to move towards the shoulder by bending the elbow. These muscles include the biceps brachii, brachioradialis, and brachialis. The biceps brachii is the most superficial of the flexors, creating motion at both the elbow and shoulder joints. It is the most visible mass on the front of the arm, with two heads originating at the shoulder joint and inserting on the radius bone below the elbow.
The brachioradialis, on the other hand, originates on the upper arm near the elbow joint and terminates on the forearm. This muscle not only helps to flex the elbow but also adds visible mass to the front of the forearm. By performing hammer curls, you can effectively target and strengthen these elbow flexor muscles.
To perform a hammer curl, hold a pair of dumbbells with a neutral grip, palms facing each other. Stand or sit with your back straight and elbows against your sides. Curl the dumbbells up towards your shoulders while keeping your upper arms still and perpendicular to the floor. Squeeze your biceps at the top of the movement and then slowly lower the dumbbells back to the starting position.
By incorporating hammer curls into your fitness routine, you can effectively strengthen the elbow flexors, improve your curling strength, and enhance the appearance of your arms.

Hammer curls vs. bicep curls
Hammer curls and bicep curls are both exercises that target the muscles in the upper arms. They are both single-joint, isolation exercises that work the muscles in different ways. Both exercises are excellent for building arm strength and improving grip power.
Hammer Curls
Hammer curls are a type of isolation exercise that mainly targets the bicep. They also target the brachioradialis, a key forearm muscle, and the brachialis. The movement of the hammer curl builds wrist strength and stability. The exercise is performed with a neutral grip, palms facing each other, which allows more focus on the short head of the bicep. This grip positioning also allows for the lifting of heavier weights, which can add mass to the arms. Hammer curls are a great way to build strength in all three muscles that bend the elbow.
Bicep Curls
Bicep curls are also an isolation exercise, designed to build the entire bicep muscle area. They are performed with an "anatomically neutral" position, with the palm facing forward in line with the chest and shoulders. This positioning ensures relatively even recruitment across the bicep muscles. Bicep curls offer a wide range of variations, including preacher curls, concentration curls, and incline curls. These target different parts of the biceps and provide additional stimulation.
Both exercises have their benefits and can be incorporated into a well-rounded workout routine. If your goal is to focus on bicep development and achieve muscle peak, bicep curls should take precedence. However, if you want to target additional muscles and promote a balanced and well-rounded arm appearance, hammer curls are the better option. Hammer curls also improve grip strength and stability, which can be beneficial in various exercises and daily activities.
It is important to note that functional training that focuses on strengthening multiple muscle groups is also essential to gain functional strength and improve core stability. This type of training can help prepare your muscles for everyday tasks and activities and reduce the risk of injury.
