Description

An exercise which targets the biceps and forearms by performing a curling motion while sitting on an exercise ball for added stability challenge.

How to Do Dumbbell Hammer Curl on Exercise Ball

  1. 1
    Setup

    Sit on an exercise ball with your feet flat on the floor, hip-width apart, ensuring your knees are bent at a 90-degree angle and your core is engaged to maintain balance.

  2. 2
    Setup

    Hold a dumbbell in each hand with a neutral grip (palms facing each other), letting your arms hang fully extended by your sides.

  3. 3

    Keeping your elbows tucked close to your torso, exhale as you slowly curl both dumbbells upwards towards your shoulders, contracting your biceps and forearms.

  4. 4

    Continue curling until your forearms are nearly vertical, ensuring your wrists remain straight and do not flex.

  5. 5

    Inhale as you slowly lower the dumbbells back to the starting position with control, fully extending your arms without locking your elbows at the bottom.

Tips

  • Maintain a stable torso by actively engaging your abdominal muscles throughout the movement to prevent rocking on the exercise ball.
  • Focus on squeezing your biceps and forearms at the top of the curl, ensuring the movement is driven by muscle contraction, not momentum.
  • Keep your elbows stationary and tucked close to your sides; avoid letting them flare out or move forward during the curl.
  • Control the eccentric (lowering) phase for 2-3 seconds to maximize muscle engagement and promote strength gains.

Common Mistakes

  • ×Rocking on the ball: Avoid using momentum from your torso by keeping your core tight and movement isolated to your arms.
  • ×Flaring elbows: Prevent your elbows from moving away from your body by keeping them pinned to your sides throughout the curl.
  • ×Rushing the eccentric phase: Lower the dumbbells slowly and under control to fully engage the muscles and prevent injury.
