NASM-CPT, CSCS certified trainers. Every guide is built from peer-reviewed research and real coaching experience.
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.

When to Use the Cross Body Hammer 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.
What are common Cross Body Hammer Curl mistakes to avoid?
Swinging body for momentum - reduces muscle targeting.
Bouncing or using momentum during the Cross Body Hammer Curl takes work away from your Brachialis and puts your connective tissue at risk. Control the weight through the full range — if you can't, lower the load.
Curling too far across - creates shoulder strain.
Without proper shoulder positioning during the Cross Body Hammer Curl, your Brachialis can't fully engage. Set your shoulder blades down and back before you start, and maintain that position throughout each rep.
Moving elbow position - decreases isolation.
Letting your elbows drift wide during the Cross Body Hammer Curl shifts load onto your shoulder joint instead of your Brachialis. Keep them tucked at about 45 degrees to protect your rotator cuff and keep tension where it belongs.

How to Program the Cross Body Hammer Curl
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.
