Bicep and hammer curls are exercises that target and strengthen the muscles in your arms. Both exercises are great for building arm strength and improving overall fitness. While bicep curls focus on the bicep muscle, hammer curls target the bicep, brachialis, and brachioradialis muscles. The bicep muscle is made up of five different muscles, and curls are a great way to target and strengthen these muscles. The bicep curl is a pulling motion of only the elbow, while the hammer curl is a pulling exercise that targets the bicep and forearm muscles.

What You'll Learn
Biceps Brachii
The biceps brachii works across three joints: the glenohumeral, elbow, and radio-ulnar joints. It is involved in flexion and supination (outward rotation) of the forearm, facilitated by a 90-degree rotation as it connects to the radius. The biceps are used in various tasks, such as lifting, throwing, and racket sports.
During a bicep curl, the biceps brachii is the primary mover, but other muscles are also recruited from the upper and lower arms. The biceps brachii contracts, pulling the forearm up and bending the arm at the elbow. The brachialis muscle, located under the biceps brachii, also assists in flexing the elbow, along with the brachioradialis muscle. Additionally, the wrist flexor muscles, such as the carpi radialis and carpi ulnaris, are engaged during a bicep curl, allowing the wrist to flex and the fingers to curl.
The bicep curl is an isolation exercise specifically targeting the biceps brachii. It is a pulling motion at the elbow, and various equipment can be used to perform this exercise, such as dumbbells, kettlebells, or barbells.

Brachialis
The brachialis is a muscle in the upper arm that flexes the elbow. It is located beneath the biceps brachii and makes up part of the floor of the cubital fossa (elbow pit). The brachialis is the prime mover of elbow flexion, generating about 50% more power than the biceps. It originates from the anterior surface of the distal half of the humerus, near the insertion of the deltoid muscle, and embraces it by two angular processes. The brachialis is a broad muscle, with its broadest part located in the middle rather than at either of its extremities.
The brachialis is commonly injured by repetitive forceful contractions or muscular contractions with the arm in hyperextension. This is often seen in climbers due to the pronation of the hand and the extended starting position. Physical activities that involve a lot of pull-ups, curls, and rope climbing can also cause brachialis muscle pain. A strain to the brachialis tendon can cause a patient to experience a lack of elbow extension due to painful end-range stretching of the tendon.
The brachialis often has dual innervation, medially innervated by the musculocutaneous nerve and laterally by the radial nerve. The majority of the motor supply is provided by the musculocutaneous nerve. The radial nerve descends in the groove between the brachialis and brachioradialis muscles, above the elbow. The brachialis is supplied by muscular branches of the brachial artery and by the recurrent radial artery.
The brachialis is the only pure flexor of the elbow joint, producing the majority of force during elbow flexion. It is not affected by pronation or supination of the forearm and does not participate in pronation and supination due to its lack of attachment to the radius. The brachialis is considered the workhorse of the elbow.

Brachioradialis
The brachioradialis is a key forearm muscle that assists the brachialis in flexing the elbow. It connects the humerus bone to the lower arm bone, or radius. Hammer curls are a great way to target this muscle. This exercise is a pull movement typically done with dumbbells, but it can also be performed with a kettlebell, barbell, or TRX Suspension Trainer.
Hammer curls are an isolation exercise that targets the bicep, but they also work the brachioradialis and build wrist strength and stability. The movement involves a pulling motion of the elbow, similar to a bicep curl. However, to focus on the brachioradialis, you can try cross-cable hammer curls, which force a supinated position. This means the arm must pronate into a neutral position, engaging the brachioradialis.
Another way to target the brachioradialis is with pronation curls. This exercise is popular among arm wrestlers and involves stabilising the wrist throughout the curl. Reverse curls also work the brachioradialis, as well as the muscles above it.
The brachioradialis is an important muscle for arm wrestlers and anyone seeking a "complete forearm look". By incorporating exercises like hammer curls, pronation curls, and reverse curls, you can effectively target and develop this muscle.

Wrist flexors
Wrist curls are an excellent way to strengthen your wrists and forearms. They are a targeted forearm exercise that helps improve grip strength and overall athletic performance. The wrist curl is particularly effective in strengthening the wrist flexors, which are the muscles located on the underside of your forearm and are responsible for flexing your wrist.
To perform a wrist curl, you can use a variety of equipment, including barbells, dumbbells, and plates. The exercise involves moving only your wrists while keeping your forearms stationary. It is important to start with light weights and gradually increase the load over time to improve your range of motion and build muscle endurance.
When performing a wrist curl with your palms facing up, you target the wrist flexors. This can be done in a seated position, with your forearms resting on your thighs or on a bench. You can hold a dumbbell with an underhand grip, allowing the weight to roll down to your fingertips, and then curl your wrists upward, lifting the weight.
Reverse wrist curls, on the other hand, target the wrist extensors, which are the muscles located on the back of your forearm and responsible for extending your wrist. These are performed with your palms facing down, either with an underhand grip or by holding a barbell behind your back.
Wrist curls are an effective way to isolate and overload the often-neglected flexor group, leading to significant hypertrophy and strength gains. They also help improve grip strength, which is crucial in many athletic and everyday activities, such as carrying groceries or opening jars.

Elbow flexors
The elbow is a complex joint where the upper arm bone (humerus) meets the two bones of the forearm (radius and ulna). It comprises several muscles, tendons, and ligaments that facilitate movement and stability.
The elbow flexors are the muscles that allow you to bring your hand to your shoulder. These muscles are targeted by exercises such as hammer curls, which are performed with the palms facing each other. Hammer curls work the biceps brachii, brachioradialis, and brachialis muscles. The brachialis is the least visible but also the strongest flexor of the elbow during the hammer curl.
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 but also gives visible mass to the front of the forearm. The brachialis also originates on the lower portion of the upper arm bone and attaches to the ulna, the large inside bone of the forearm.
Bicep curls can also cause elbow pain due to improper technique, overuse injuries, and underlying conditions like tendonitis. The most common type of elbow pain during and after lifting is improper bicep curls. For example, gripping the bar or dumbbell too tightly activates the flexor tendon that allows your wrist to bend or curl forward, which can lead to inner elbow pain and golfer's elbow.
