Movement media
Accessible movement summary
Set an incline bench, sit with the back supported, and let the arms hang beside the torso. Begin with palms forward, shoulders relaxed, and elbows slightly behind the body. Curl the dumbbells without moving the upper arms or lifting the shoulders. Lower slowly until the elbows are extended and the biceps are lengthened comfortably.
Key cue: Keep upper arms still.
