Does Hammer Curls Work Triceps


Does Hammer Curls Work Triceps: The triceps brachii, often referred to simply as the triceps, is a three-headed muscle that occupies the back of the upper arm. It plays a crucial role in extending the elbow joint and contributes significantly to arm strength and overall arm aesthetics. While hammer curls primarily emphasize the brachialis and brachioradialis, which are the muscles on the front of the upper arm, there is some involvement of the triceps during the execution of this exercise.

During a hammer curls triceps are engaged to some extent to stabilize the elbow joint as you lift the weight. This stabilization is necessary to prevent excessive movement and maintain control throughout the exercise. The triceps are not the primary movers during hammer curls, and the amount of work they receive is relatively minimal compared to exercises specifically designed to target the triceps, such as tricep extensions or dips.

The indirect activation of the triceps during hammer curls can be beneficial for individuals looking to develop balanced and well-rounded arm muscles. Incorporating a variety of exercises that target different muscle groups within the arms, including both biceps and triceps, can lead to more comprehensive arm development and strength. Hammer curls are not a primary triceps exercise, they do involve the triceps to some extent for stabilization.

Does Hammer Curls Work Triceps

Are hammer curls for biceps or triceps?

Hammer curls are isolation movements, which means that hammer curls target just the bicep muscle. Of the two bicep heads, hammer curls target the long one.

The Anatomy of Hammer Curls

Before we determine whether hammer curls primarily target the biceps or triceps, it’s important to understand the exercise itself. Hammer curls are executed with a neutral grip, where your palms face each other throughout the movement. This grip variation distinguishes hammer curls from traditional bicep curls, where the palms are supinated (facing upward) and primarily emphasize the biceps.

Primary Target: The Brachialis and Brachioradialis

Hammer curls are renowned for their effectiveness in developing the brachialis and brachioradialis muscles. The brachialis, located beneath the biceps, and the brachioradialis, running along the forearm, are the primary muscles worked during hammer curls. These muscles are responsible for elbow flexion and forearm strength. Hence, it’s safe to say that the primary emphasis of hammer curls is on these muscles.

Secondary Involvement of the Triceps

While the brachialis and brachioradialis take center stage during hammer curls, the triceps do come into play but to a lesser degree. The triceps, a three-headed muscle located at the back of the upper arm, are responsible for extending the elbow joint. During hammer curls, as you lift the weight upward, your triceps help stabilize the elbow joint to maintain control of the movement.

Do bicep curls work the triceps also?

In contrast to the biceps, the triceps acts as an antagonist muscle during curling movements. This means they perform the opposite motion of the biceps. While they aren’t the primary muscle being worked during a curl, they still play a role in the movement.

Understanding Bicep Curls

Before we can assess the involvement of the triceps, it’s essential to comprehend the mechanics of bicep curls. Bicep curls typically involve flexing the elbow joint to lift a weight, whether it’s a dumbbell, barbell, or resistance band. The movement primarily targets the biceps brachii, a two-headed muscle located on the front of the upper arm, responsible for elbow flexion.

Primary Focus: The Biceps Brachii

The name itself, “bicep curl,” suggests that the exercise primarily emphasizes the biceps. The biceps brachii consist of a short head and a long head, both of which play a significant role in bending the elbow. As you perform bicep curls, these muscle heads contract concentrically and eccentrically, leading to bicep growth and strength development.

Triceps Involvement: A Stabilizing Role

Now, let’s address the triceps’ role during bicep curls. While bicep curls are predominantly a biceps exercise, the triceps do play a secondary role in stabilizing the elbow joint. The triceps, a three-headed muscle located at the back of the upper arm, are responsible for extending the elbow. During bicep curls, they engage to keep the elbow joint steady and support the movement. This stabilization is essential to prevent unnecessary movement and maintain control throughout the exercise.

Direct Triceps Engagement

It’s crucial to clarify that bicep curls do not provide significant direct engagement or resistance to the triceps. Unlike exercises specifically designed to target the triceps, such as tricep extensions or dips, bicep curls primarily serve to work the biceps. The triceps’ involvement is more about assisting in maintaining proper form and control during the exercise rather than undergoing substantial contraction and extension.

Do hammer curls give you big arms?

Hammer curls are an extremely popular exercise because, when the movement is done correctly, it: Increases bicep size and strength.

Targeting Specific Muscles

To understand the impact of hammer curls on arm size, it’s crucial to recognize the primary muscles they work. Hammer curls primarily target the brachialis and brachioradialis muscles. The brachialis lies beneath the biceps, while the brachioradialis extends from the forearm to the upper arm. These muscles contribute significantly to elbow flexion and forearm strength. When well-developed, they can indeed contribute to the appearance of larger arms.

Secondary Involvement of Biceps

While hammer curls place emphasis on the brachialis and brachioradialis, they also engage the biceps to some extent. The biceps brachii, consisting of the short head and long head, assist in elbow flexion during hammer curls. This means that hammer curls are not just an isolation exercise for the brachialis and brachioradialis but also provide indirect stimulation to the biceps.

Overall Arm Aesthetics

Big arms are not solely defined by the size of the biceps or triceps. Balanced arm development, which includes well-developed brachialis, brachioradialis, and triceps, can contribute significantly to the aesthetics of the arms. Hammer curls can help achieve this balance by targeting the often-neglected brachialis and brachioradialis.

Variability in Results

The effectiveness of hammer curls in building big arms may vary from person to person. Factors such as genetics, diet, overall workout routine, and consistency play a crucial role in determining the outcomes. What works for one individual may not yield the same results for another. It’s essential that arm size and muscle growth are influenced by a combination of exercises, nutrition, and recovery.

What is the most effective curl?

Arguably the most efficient exercise in yielding maximum bicep growth, a recent study by the American Council on Exercise found that the seated concentration curl yielded 97% bicep activity in contrast to EZ-bar curls (wide grip 75%; narrow grip, 71%), incline curls (70%), and preacher curls (69%).

Barbell Bicep Curl

The barbell bicep curl is a classic and foundational exercise for bicep development. It targets both the short and long heads of the biceps brachii, providing a well-rounded workout for the biceps. Using a barbell allows you to lift heavier weights, promoting muscle growth through progressive overload.

Dumbbell Bicep Curl

Dumbbell bicep curls offer a high degree of flexibility in terms of range of motion and grip variations. This exercise allows for unilateral training, which can help address muscle imbalances. Dumbbell curls engage the stabilizer muscles more actively, contributing to overall arm strength and coordination.

Preacher Curl

The preacher curl is performed using a specialized bench that isolates the biceps, reducing the involvement of other muscle groups. This isolation can help in concentrating the effort on the biceps, making it an effective exercise for building muscle mass.

Concentration Curl

Concentration curls are performed while sitting on a bench with the arm fully extended and resting against the inner thigh. This exercise allows for precise targeting of the biceps, particularly the peak of the muscle. It is an excellent choice for refining bicep definition.

Hammer Curl

The hammer curl, unlike traditional curls, features a neutral grip (palms facing each other). This exercise primarily targets the brachialis and brachioradialis muscles but also engages the biceps. Hammer curls can be effective for achieving balanced arm development.

What are hammer curls best for?

Hammer curls are biceps curls performed with your hands facing each other. They’re beneficial to add mass to your arms and can help focus more attention on the short head of the biceps. They may be easier to tolerate than the traditional biceps curl.

Brachialis and Brachioradialis Development

Hammer curls are best known for their effectiveness in targeting the brachialis and brachioradialis muscles. These muscles are situated in the front of the upper arm and the forearm, respectively. By working these muscles, hammer curls contribute to overall arm development. The brachialis, in particular, lies beneath the biceps and can give the arms a fuller and more defined appearance when well-developed.

Balanced Arm Development

One of the significant advantages of hammer curls is their ability to promote balanced arm development. While traditional bicep curls primarily target the biceps, hammer curls engage the brachialis, brachioradialis, and to some extent, the biceps. This balance can help prevent muscle imbalances and lead to aesthetically pleasing, symmetrical arms.

Forearm Strength and Grip Enhancement

Hammer curls involve a neutral grip, which places significant emphasis on the forearm muscles and grip strength. Strong forearms and a solid grip are essential for a wide range of activities, including weightlifting, sports, and daily tasks. Regularly incorporating hammer curls into your routine can help improve forearm strength and grip endurance.

Functional Fitness

Functional fitness refers to exercises that have practical applications in everyday life. Hammer curls mimic activities like carrying grocery bags or lifting objects with a neutral grip. By strengthening the muscles involved in these movements, hammer curls can enhance your functional fitness and make daily tasks easier and more efficient.

Why are hammer curls so effective?

Hammer curls are particularly effective because they target the outer head of the biceps brachii, the brachialis and the brachioradialis while engaging additional back and chest muscles. When performed correctly, hammer curls can maximize your arm gains and help improve grip strength.

Targeting Multiple Muscles

Hammer curls are known for their unique ability to engage multiple muscle groups simultaneously. While traditional bicep curls primarily focus on the biceps brachii, hammer curls involve the brachialis and brachioradialis muscles to a significant extent. The brachialis, in particular, lies beneath the biceps and contributes to the appearance of fuller, more developed arms when strengthened.

Balanced Arm Development

One key reason hammer curls are effective is their role in promoting balanced arm development. Unlike exercises that exclusively target the biceps, hammer curls engage both the front of the upper arm (brachialis) and the forearm (brachioradialis). This balanced approach helps prevent muscle imbalances, ensuring that all aspects of the arm receive adequate attention for symmetry and aesthetics.

Grip Strength and Forearm Endurance

The neutral grip used in hammer curls places a significant emphasis on grip strength and forearm endurance. The brachioradialis muscle is actively involved in this exercise, helping to improve grip stability. Strong forearms and a solid grip have practical applications in daily life and sports, making hammer curls a valuable addition to any fitness routine.

Progressive Overload

Effective strength training relies on the principle of progressive overload, which means gradually increasing the resistance or weight lifted over time. Hammer curls lend themselves well to progressive overload because they can be performed with a variety of equipment, including dumbbells and barbells. This adaptability allows individuals to challenge their muscles continually and promote growth.

How many hammer curls is good?

Bend your elbows, bringing the dumbbells up toward your shoulders while keeping your upper arms in line with your trunk. Your palms will stay facing each other. Pause for a 1–2 count, and then slowly lower the dumbbells back to the starting position at your sides. Perform 2–3 sets of 8–15 repetitions.

Establishing Your Fitness Goals

The first step in determining how many hammer curls are appropriate for you is to clarify your fitness goals. Are you looking to build muscle mass, increase strength, improve arm definition, or enhance functional fitness? Your goals will influence the number of reps and sets you should aim for.

Consider Your Experience Level

Your experience level plays a crucial role in determining the volume of hammer curls. Beginners should typically start with a lower volume to allow their muscles and joints to adapt to the exercise. Intermediate and advanced individuals can gradually increase the workload over time.

dividual Variation

It’s essential to recognize that individual variation plays a significant role in determining the optimal number of hammer curls. What works for one person may not be suitable for another. Pay attention to how your body responds to different rep and set schemes, and be open to adjusting your training volume based on your progress.

Rest Periods

Incorporate appropriate rest periods between sets to allow for muscle recovery. Resting for about 1-2 minutes between sets is generally to ensure you can maintain the quality of your reps and sets.


To prevent plateaus and continue making progress, consider implementing a periodization plan. This involves cycling through different rep and set schemes over time. For example, you might start with a strength-focused phase and then transition to a hypertrophy phase.

Can curls grow triceps?

Develop muscular strength: One of the main benefits of tricep curls is that they help to isolate the tricep muscles. This means that you’ll be able to work on these specific muscles without engaging other parts of your body.

Stabilization: During curls, the triceps play a role in stabilizing the elbow joint. They help keep the joint steady as the biceps contract to lift the weight. While this stabilization is secondary, it still involves the triceps and contributes to their overall engagement during the exercise.

Balanced Arm Development: Effective arm training often involves balancing the development of both the biceps and triceps. While curls emphasize the biceps, they can be part of a well-rounded arm training routine that also includes dedicated triceps exercises. Achieving balanced arm development can lead to better aesthetics and functional strength.

Muscle Confusion: Introducing variety into your workouts is a fundamental principle for muscle growth. Incorporating different exercises, including curls, can help prevent plateaus and stimulate muscle growth. When you challenge your muscles in new ways, even indirectly involving the triceps, you can promote overall arm development.

Isometric Engagement: At certain points during curls, especially when controlling the weight on the way down (the eccentric phase), the triceps undergo isometric engagement. While this doesn’t lead to significant triceps growth on its own, it contributes to overall arm tone and strength.

Does Hammer Curls Work Triceps


While hammer curls primarily target the brachialis and brachioradialis muscles in the front of the upper arm, they do involve the triceps to a limited extent for stabilization. The triceps help maintain control of the elbow joint during the exercise. To recognize that hammer curls are not a dedicated triceps exercise, and their primary focus is on the anterior arm muscles.

To effectively target and strengthen the triceps, it is advisable to incorporate exercises specifically designed for triceps development, such as tricep extensions, dips, or close-grip bench presses, into your workout routine. While hammer curls can contribute to overall arm development and aesthetics, they should be complemented by exercises that directly engage the triceps for a well-rounded and balanced approach to arm training.

It’s worth mentioning that achieving a balanced and aesthetically pleasing arm appearance often involves a combination of both bicep and tricep development. The interplay between these opposing muscle groups can enhance the overall visual appeal of the arms. While hammer curls may not be a primary triceps exercise, they can play a valuable role in creating harmonious arm aesthetics when combined with targeted triceps workouts.
