Description

An exercise that targets your biceps individually with a dumbbell.

How to Do Dumbbell Alternate Biceps Curl

  1. 1
    Setup

    Stand tall with your feet hip-width apart, holding a dumbbell in each hand with a supinated grip (palms facing forward). Let your arms hang fully extended by your sides.

  2. 2
    Setup

    Retract and depress your shoulders, engage your core, and maintain a neutral spine with your gaze forward throughout the exercise.

  3. 3

    Keeping your elbow tucked close to your side, slowly curl one dumbbell upwards towards your shoulder, squeezing your biceps at the peak contraction. Exhale as you curl.

  4. 4

    Slowly lower the dumbbell back to the starting position with control, fully extending your arm and feeling a stretch in your biceps. Inhale as you lower the weight.

  5. 5

    Alternate arms, repeating the curling motion with the other arm while maintaining a steady pace and focusing on isolating the biceps.

Tips

  • Actively squeeze your biceps at the peak of the contraction and focus on feeling the muscle work throughout the entire range of motion, especially during the eccentric (lowering) phase.
  • Control the negative portion of the lift by slowly lowering the dumbbell for 2-3 seconds to maximize time under tension and stimulate muscle growth.
  • Keep your elbows pinned to your sides and avoid letting them drift forward, which can engage your anterior deltoids and reduce biceps isolation.
  • Maintain a stable torso without swinging or using momentum; if you find yourself swaying, reduce the weight to ensure proper form and biceps activation.

Common Mistakes

  • ×Using momentum to lift the weight by arching your back or swinging the dumbbells reduces bicep engagement; instead, keep your torso stationary and initiate the movement solely with your biceps.
  • ×Not fully extending the arm at the bottom or not achieving a peak contraction at the top limits muscle activation; ensure you achieve a full stretch at the bottom and a hard squeeze at the top.
  • ×Allowing your elbows to move away from your sides engages other muscles and reduces biceps isolation; keep your elbows tucked in throughout the entire curl to maintain tension on the biceps.
