Dumbbell Alternate Biceps Curl

Stand with your feet shoulder-width apart, holding a dumbbell in each hand, palms facing forward. Keeping your elbows close to your torso, exhale and curl one dumbbell up towards your shoulder while keeping the other arm extended. Inhale and slowly lower the dumbbell back to the starting position. Alternate arms and repeat.

How to perform the Dumbbell Alternate Biceps Curl

  1. Set up. Set up in a stable, balanced starting position appropriate for the Dumbbell Alternate Biceps 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.
