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.
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3 sets of 10-12 reps per arm. Rest 45 seconds.
