How to Put in Your Workout Split

The dumbbell cross-body hammer curl targets the biceps, brachialis, and forearms, enhancing arm strength, grip, and upper body definition. This exercise ensures balanced arm development and boosts upper body stability.

  • Upper Body — Add it to your upper body workout for better arm strength and definition. Pair it with babell bicep curls and shoulder presses.
  • Arm Day — Include it in an arm-focused routine for balanced muscle development. Pair with tricep dips and barbell preacher curls.
  • Full Body — Incorporate it into a full-body workout for overall muscle engagement and conditioning. Pair with squats and chest presses.

Once you have your workout split, it's time to work out the correct loading amount. These are calculated using your one repetition maximum (1RM). This is the maximum amount of weight you can lift with good form.

Here’s how to do it based on training style. 

  • Strength And Power Training — Use heavier weights with lower reps to build arm strength. Use 80%–100% of your 1RM. Rest for 2–3 minutes between sets. 
  • Hypertrophy Training — Opt for moderate weights with higher reps to promote muscle growth and definition. Use 60%–80%  of your 1RM. Rest for 45–60 seconds between sets.
  • Endurance Training — Choose lighter weights with high reps to improve muscular endurance and stability. Use 40%–60% of your 1RM. Rest for 45–60 seconds between sets.

Primary Muscle Groups

Biceps Short Head

Most inside portion of the biceps. Located at the front of your upper arm closest to your chest.

Wrist Extensors

Muscles that make up the back portion of your lower arm, between your elbow and wrist.

Biceps Short Head

The biceps brachii, at the front of your upper arm, consists of two heads. These are the short head and long head. The biceps short head originates from the humerus, or upper arm, and inserts into the ulna, or forearm. It’s the inner part of the biceps brachii.

During the dumbbell cross-body hammer curl, this muscle activates significantly to lift the weight across the body. When using a neutral hand position, the biceps brachii shows a maximum voluntary contract of approximately 20%.

Include this curl to target the biceps short head. It can be used alongside other short-head bicep exercises to promote balanced bicep development.

Wrist Extensors 

The wrist extensors are located on the outside of the forearm. They work to extend the wrist and fingers. During the dumbbell cross-body hammer curl, they help stabilize the wrist and prevent it from overextending.

Improved wrist control enhances forearm functionality and performance. Strong wrist extensors are essential for tasks demanding wrist strength, providing a solid foundation for various physical activities.

Secondary Muscle Groups

Biceps Long Head

Most outside part of your bicep.The front of your upper arm.

Biceps Long Head

The biceps long head works with the short head to perform elbow flexion during the dumbbell cross-body hammer curl. Alongside this, it stabilizes the shoulder to ensure targeted muscle activation.

This muscle is especially active when the arm is supinated, meaning palms facing up. Because the dumbbell cross-body hammer curl uses a neutral grip, the long head is a secondary mover.

Strengthening the biceps long head enhances arm aesthetics and strength. A well-developed biceps long head boosts upper arm appearance. It also improves performance in pulling and lifting activities.

Like the short head, use long-head bicep exercises to better target this head of the biceps. When done correctly, this can lead to better overall bicep development.

Equipment

Dumbbells

Dumbbells

You can use these for a wide range of unilateral and bilateral exercises. Avoid using momentum to lift. Ensure a secure grip to prevent drops.

Who Should Do?

People Looking To Build Arm Strength

When looking to build arm strength, you need to work the biceps and triceps equally to ensure even arm development. Performing a variety of bicep training movements makes up a large part of this.

The dumbbell cross-body hammer curl is ideal for individuals aiming to strengthen their biceps and forearms. It targets key bicep muscles involved in lifting and pulling movements, enhancing overall arm strength and muscular endurance. Incorporate this exercise into your routine to develop functional arm strength for daily activities and sports.

Regularly performing cross-body hammer curls enhances grip strength, contributing to better hand and forearm strength during various tasks and activities. Alongside this, grip strength has recently been proposed as a vital sign of health.

People Seeking Arm Definition

For those interested in sculpting their arms, the dumbbell cross-body hammer curl is effective in isolating the biceps muscles. 

While it primarily targets the biceps short head, it also works the long head as a secondary mover. The neutral grip position also helps to work the brachialis, which is a muscle located underneath the bicep.

By working each of these muscles, the dumbbell cross-body hammer curl promotes better arm definition. Ensure you perform it correctly using the guide above.

General Gymgoers

The dumbbell cross-body hammer curl is beneficial for general gymgoers seeking a well-rounded workout. As a general gymgoer, your goals tend to include improving appearance and enhancing muscle strength.

The dumbbell cross-body hammer curl is easy to perform and progress as needed. It possesses a small initial learning curl and teaches beginners to keep elbows close to their body when curling.

When programmed alongside traditional bicep exercises such as barbell curls and preacher curls, the dumbbell cross-body hammer curl is great for general gymgoers.

Who Should Not Do?

Individuals With Elbow Or Wrist Injuries

The dumbbell cross-body hammer curl can worsen conditions for those with wrist or elbow injuries. When presenting with these conditions, pain and limited range of motion may be seen.

Therefore, the elbow extension and flexion movements may stress these joints excessively. This may reduce healing and increase discomfort or pain, potentially delaying recovery or causing further injury.

It’s crucial to evaluate personal limitations and consult a healthcare provider before attempting exercises that target sensitive or injured areas.

Beginners With Limited Grip Strength

Good grip strength is important for proper power generation and correct movement patterns in sports performance and exercise.

Beginners may find the dumbbell cross-body hammer curl challenging due to weak grip strength. This exercise requires strong wrist extensors and flexors to grip the dumbbell effectively. These muscles are crucial to keeping the correct hand position, making it harder for those with limited grip strength.

Benefits Of The Exercise

Promotes Arm Functionality 

Well-developed arm coordination is vital for the performance of daily movement patterns and exercise. The dumbbell cross-body hammer curl enhances arm functionality by targeting the biceps and forearm muscles. These muscles are crucial for everyday movements like lifting groceries and carrying bags.

This exercise improves muscle coordination and range of motion. The controlled movement of lifting the dumbbell across the body mimics functional activities, enhancing muscle activation and joint stability. Functional examples include getting dressed and placing an item on a kitchen shelf.

Including the dumbbell cross-body hammer curl in your routine improves arm coordination and functionality. This leads to better performance of everyday tasks and enhanced physical fitness.

Increases Strength

Increasing strength requires a large resistance training stimulus. This allows your body to adapt to the old stimulus and become more efficient at dealing with it next time. This is known as the body’s adaptive way of improving function.

The dumbbell cross-body hammer curl is great for increasing strength for several reasons. It uses a movement pattern that isolates the key elbow flexors involved in many strength-based movements. Examples include the barbell bent-over row and the pull-up. 

Because of the simple movement pattern, it’s easy to learn and progress. In terms of strength adaptations, this means it’s easy to progressively overload. As a key factor in strength training, this makes it a great way to improve arm strength. 

Improves Muscular Endurance

Performing multiple sets of the dumbbell cross-body hammer curl boosts muscular endurance in the arms. The simple movement pattern allows for high volume, helping to withstand prolonged physical activities and resistance training sessions.

Alongside muscular endurance, resistance training volume is shown to be a key determinant of muscle growth, or muscular hypertrophy. These tend to go hand in hand, with the difference relating to set and rep ranges. 

To enhance muscular endurance using the dumbbell cross-body hammer curl, use the suggested set and rep ranges above for the majority of your training.
