Seated dumbbell curl

Sit upright against a vertical bench back, feet planted. Dumbbells at your sides, palms facing forward, elbows under the shoulders.

Seated dumbbell curl
  1. 1Keep the back on the pad so the torso cannot swing.
  2. 2Curl toward the shoulders. The elbows stay at the ribs and the palms stay facing forward.
  3. 3Lower until the elbows are straight.

Easy to miss: Leaning off the pad, or turning the grip into a hammer curl.

Copper on the figure is a prime mover. The softer tone helps.
