Dumbbell Alternate Seated Hammer Curl

Sit upright on a bench with dumbbells in each hand at your sides. Keep your elbows close to your body. Curl one dumbbell up towards your shoulder, without twisting your wrist. Slowly lower it back down and repeat with the other arm. Alternate between the two arms for the desired number of reps.

How to perform the Dumbbell Alternate Seated Hammer Curl

  1. Set up. Set up in a stable, balanced starting position appropriate for the Dumbbell Alternate Seated Hammer Curl using your dumbbell.
  2. Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your biceps.
  3. Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.

Coaching cues

  • Move with intent — every rep should feel deliberate, not rushed.
  • Drive force through your biceps rather than momentum.
  • Keep your breathing steady: exhale on the hard part, inhale on the reset.

Common mistakes

  • Using too much weight and losing positional control.
  • Cutting the range of motion short and missing the target muscle.
  • Letting your spine round or hyperextend instead of staying neutral.
