About This Exercise

A bicep curl variation performed with a neutral grip (palms facing each other). This grip targets the brachioradialis and brachialis in addition to the biceps, helping build overall arm thickness.

How to Perform

  1. 1

    Setup

    Stand with feet shoulder-width apart, holding a dumbbell in each hand at your sides with palms facing your body (neutral grip).

  2. 2

    Curl Up

    Keeping your upper arms stationary and elbows close to your sides, curl the dumbbells upward by bending at the elbows. Maintain the neutral grip throughout.

  3. 3

    Top Position

    Squeeze your biceps at the top of the movement when the dumbbells are near shoulder height.

  4. 4

    Lower

    Slowly lower the dumbbells back to the starting position with control. Avoid swinging or using momentum.

Form Tips

  • Keep your elbows pinned to your sides throughout the movement
  • Maintain the neutral (palms facing each other) grip at all times
  • Control the weight on the way down — no dropping
  • Stand tall with core engaged, avoid swaying

Common Mistakes to Avoid

  • Swinging the body to generate momentum
  • Letting the elbows drift forward
