Description

A bicep curl variation where the user sits on a stability ball with a dumbbell in each hand, then flexes and extends the arms to target the biceps.

How to Do Weighted Seated Bicep Curl (on stability ball)

  1. 1
    Setup

    Sit upright on a stability ball with your feet flat on the floor, hip-width apart, holding a medicine ball with both hands.

  2. 2
    Setup

    Position the medicine ball against your upper thighs, palms facing up, ensuring your torso is stable and core is engaged.

  3. 3

    Exhale as you slowly curl the medicine ball upwards towards your chest, contracting your biceps and brachialis.

  4. 4

    Keep your elbows tucked close to your sides throughout the movement, preventing them from flaring out or moving forward.

  5. 5

    Inhale as you slowly lower the medicine ball back to the starting position, fully extending your arms without locking the elbows.

Tips

  • Maintain a stable torso by engaging your core and glutes on the stability ball, preventing any compensatory swaying or rocking.
  • Focus on a controlled concentric (lifting) and eccentric (lowering) phase to maximize time under tension and muscle engagement.
  • Ensure your wrists remain neutral throughout the curl, avoiding any flexion or extension that could strain the wrist joint.
  • To enhance brachialis activation, focus on a strong squeeze at the top of the movement, imagining pulling your forearms towards your biceps.

Common Mistakes

  • ×Using momentum to lift the medicine ball reduces muscle engagement; instead, use a strict, controlled movement focusing on bicep contraction.
  • ×Allowing elbows to flare out compromises form and shifts tension away from the biceps; keep elbows pinned to your sides throughout the curl.
  • ×Rounding your back while seated on the stability ball can strain your spine; maintain an upright posture with a neutral spine by engaging your core.
