Weighted Overhead Crunch (on stability ball)

Description

How to Do Weighted Overhead Crunch (on stability ball)

1. 1
   Setup

   Sit on a stability ball with your feet flat on the floor, shoulder-width apart, and roll down until your lower back is supported and your hips are slightly off the ball, with your torso parallel to the floor.

2. 2
   Setup

   Hold a dumbbell or weight plate with both hands, extending your arms straight overhead so the weight is directly above your chest, keeping a slight bend in your elbows.

3. 3

   Inhale, then exhale as you slowly crunch your upper body upwards, bringing your rib cage towards your hips while keeping the weight overhead and your arms extended.

4. 4

   Focus on contracting your rectus abdominis, lifting your shoulders and upper back off the ball until you feel a strong abdominal contraction.

5. 5

   Inhale as you slowly and controlledly lower your upper body back to the starting position, allowing your abs to stretch over the ball without losing tension.

Tips

• Maintain a stable lower body by keeping your feet firmly planted and hips relatively still on the ball to isolate the abdominal muscles and prevent momentum from assisting the crunch.
• Control the eccentric phase by slowly lowering your body back to the starting position, resisting gravity, to maximize muscle engagement and promote greater strength development.
• Focus on abdominal contraction by initiating the movement with your abs, visualizing your rib cage moving towards your pelvis rather than just lifting your head or shoulders.
• Keep the weight overhead throughout the movement by ensuring your arms remain extended with the weight directly above your chest to maintain constant tension on the core.

Common Mistakes

• ×Using momentum to crunch is a common error; instead, perform the movement slowly and with control, focusing on muscle contraction rather than jerking upwards.
• ×Arching the lower back excessively at the bottom of the movement should be avoided; maintain a slight posterior pelvic tilt to keep your core engaged and protect your spine.
• ×Dropping the weight too low or allowing it to drift behind your head at the bottom of the movement reduces tension; keep the weight directly overhead to maintain constant tension and proper form.
