Weighted Seated Bicep Curl (on stability ball)
Perform seated bicep curls on a stability ball with a medicine ball to isolate your brachialis and biceps, enhancing arm strength and stability.
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)
- 1Setup
Sit upright on a stability ball with your feet flat on the floor, hip-width apart, holding a medicine ball with both hands.
- 2Setup
Position the medicine ball against your upper thighs, palms facing up, ensuring your torso is stable and core is engaged.
- 3
Exhale as you slowly curl the medicine ball upwards towards your chest, contracting your biceps and brachialis.
- 4
Keep your elbows tucked close to your sides throughout the movement, preventing them from flaring out or moving forward.
- 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.
