Crunch with Medicine Ball

Description

How to do Crunch with Medicine Ball

1. 01
   Setup

   Lie supine on the floor with your knees bent at approximately 90 degrees and your feet flat on the ground, hip-width apart.

2. 02
   Setup

   Hold a medicine ball against your chest with both hands, or extend it slightly above your chest with arms slightly bent, ensuring a comfortable grip.

3. 03

   Exhale as you contract your rectus abdominis, slowly lifting your head, shoulders, and upper back off the floor, focusing on spinal flexion.

4. 04

   Continue to crunch upwards until your shoulder blades are just off the floor, maintaining a stable lower back pressed firmly into the ground.

5. 05

   Inhale slowly as you control the movement, lowering your upper body back to the starting position with your shoulders gently touching the floor.

Tips

• Focus on a slow and controlled eccentric phase (lowering) to maximize time under tension and enhance muscle engagement.
• Keep your chin slightly tucked towards your chest to maintain a neutral neck alignment and prevent strain during the crunch.
• Initiate the movement by thinking about bringing your ribs towards your hips, ensuring your abdominal muscles are driving the lift, not your neck or momentum.
• For increased difficulty, hold the medicine ball further away from your chest, extending your arms more as you crunch.

Common mistakes

• Pulling on the neck to initiate the crunch strains the cervical spine; instead, keep your gaze fixed on the ceiling and lead with your chest.
• Lifting the lower back off the floor reduces abdominal engagement and can strain the lumbar spine; ensure your lower back remains pressed into the floor throughout the movement.
• Using momentum to complete repetitions diminishes muscle activation; perform each crunch slowly and with controlled abdominal contraction.
