Cross-body hammer curls target the brachialis more aggressively than standard hammer curls by changing the curl path across your torso. The diagonal movement pattern hits the brachialis from a different angle, building arm thickness that pushes the bicep peak upward. This variation also increases brachioradialis involvement for complete forearm development.
When to use it
Include for brachialis emphasis and arm thickness.
Who it's for
All levels. Great variation for complete arm development.
Curl the dumbbell toward your opposite shoulder, not straight up like a regular curl. Keep your elbow pinned at your side—only your forearm should move. Do not rotate your torso or use shoulder movement to assist the curl. Each rep should feel like you are aiming for the opposite pec.

Stand holding dumbbells at sides with neutral grip.
Curl one dumbbell across your body toward opposite shoulder.
Keep elbow stationary at your side.
Squeeze at the top of the movement.
Lower under control to starting position.
Alternate arms for each rep.
The cross-body motion emphasizes the brachialis.
Keep your wrist neutral throughout.
Dont rotate your torso during the curl.
Include cross-body hammer curls when you want to emphasize brachialis development for arm thickness. They pair well with standard bicep curls in a superset. Program them with moderate weight for 10-12 reps per arm, alternating sides. Position them mid-workout after heavy curls but before isolation finishers.
Swinging body for momentum - reduces muscle targeting.
Bouncing or using momentum during the Cross Body Hammer Curl makes the movement harder to control and can shift work away from your Brachialis. Use a load you can move smoothly through the intended range.
Curling too far across - creates shoulder strain.
Changing your shoulder position during the Cross Body Hammer Curl can redirect the movement away from your Brachialis. Use the shoulder-blade position described in the setup and keep the motion controlled.
Moving elbow position - decreases isolation.
Letting your elbows drift away from the intended path during the Cross Body Hammer Curl can change which muscles carry the load. Use the elbow position described in the setup cues and keep it consistent through each rep.
All levels. Great variation for complete arm development.
These ranges illustrate ways to organize training. They are not an individual prescription. Adjust them for the exercise, your experience, and the rest of your program.
Heavier loads can be useful for developing maximum strength. The range shown is an example, and the load must match your current technique and capacity.
Muscle growth can occur across different loads and repetition ranges. This example is not a uniquely effective zone; your overall program and effort also matter.
This is an example of a longer set. A repetition target alone does not establish joint safety or whether the exercise is appropriate for you.
Example: 3 sets of 10-12 reps per arm. Rest 45 seconds.
Background for resistance exercises: the 2026 ACSM position stand covers healthy adults, and a load-comparison review found similar muscle growth across loads in studies using sets taken to muscular failure. These findings do not validate every exercise-specific range shown here or require training to failure.
This is one example of how Cross Body Hammer Curl could sit inside a complete workout. Your plan may use different movements after Ely checks your assessment.
