Dumbbell Alternate Biceps Curl
Description
The dumbbell alternate biceps curl is a bicep curl variation where you curl one arm at a time, alternating sides each rep. The unilateral focus allows greater concentration on each contracting bicep, exposes left-right imbalances, and reduces the temptation to use body english to grind out reps.

Dumbbell Alternate Biceps Curl Instructions
- Stand tall with feet hip-width apart, holding a dumbbell in each hand at your sides, palms facing your body.
- Pull your shoulders back, brace your core, and pin both elbows against your sides.
- Curl the dumbbell in your right hand up first, rotating your wrist so your palm faces your shoulder at the top.
- Squeeze your right bicep for one second at the top, then lower the dumbbell under control while rotating your palm back to neutral.
- Once the right dumbbell is fully extended at your side, curl the left dumbbell up using the same form.
- Continue alternating arms until you complete the desired total reps (e.g., 10 per arm = 20 total).
- Keep both elbows pinned to your sides throughout. The non-working arm rests at full extension.
- Avoid swinging or using momentum on either side.
