How to do the cross body hammer curl
- Stand up straight with a dumbbell in each hand. Your hands should be down at your side with your palms facing in.
- While keeping your palms facing in and without twisting your arm, curl the dumbbell of the right arm up towards your left shoulder as you exhale. Touch the top of the dumbbell to your shoulder and hold the contraction for a second.
- Slowly lower the dumbbell along the same path as you inhale and then repeat the same movement for the left arm.
- Continue alternating in this fashion until the recommended amount of repetitions is performed for each arm.
Muscles worked
The prime mover is the biceps brachii, which bends the elbow and rotates the forearm palm-up.
Even with a single joint doing the moving, the muscle is not working alone — the forearms hold the grip, which is often what gives out first.
How this movement works
One joint changes angle and the resistance travels toward you along a single arc. Nothing is positioned to help, so tension stays where you aimed it and the usable load drops sharply against a multi-joint pull for the same muscle. Protect the range of motion; buying weight by shortening the arc defeats the point.
It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.
What you need
Dumbbells let each side work on its own, surfacing a strength difference between limbs that a barbell would quietly cover for, and leaving the wrist free to rotate through the movement.
