Steps
- 01
Stand feet hip-width, knees soft; hold a dumbbell in each hand at the sides with the palms facing each other (thumbs forward, as if holding a hammer), wrists neutral.
- 02
Shoulders back and down, upper arms pinned to the sides of the torso, elbows fixed at the sides.
- 03
Exhale and bend both elbows together to curl the dumbbells up to the front of the shoulders, palms facing each other throughout with no rotation; the elbows do not move forward.
- 04
Pause 1 second at the top to squeeze the biceps, then inhale and lower under control to straight arms (a slight bend, not locked).
- 05
It can also be done alternating arms; control the lowering every rep, never let the dumbbells drop.
Common mistakes
- Leaning back and swinging the dumbbells up with the lower back and shoulders.
- Elbows drifting forward and the upper arms rising, turning it into a front raise.
- Wrists curling.
- Dropping the weight too fast and cutting the range short.
