How to do the Hammer Curl
- Stand tall with a dumbbell in each hand and palms facing each other.
- Let the weights hang at your sides with elbows close to your torso.
- Brace your trunk and keep your shoulders from drifting forward as you start.
- Curl one or both dumbbells upward without turning the palms up.
- Raise the weights until your forearms are nearly vertical and biceps fully shortened.
- Lower the dumbbells back to the hang with elbows staying in place.
- Begin the next rep from a dead hang without swinging your torso.
