Crunch with Medicine Ball

Description

How to Do Crunch with Medicine Ball

1. 1
   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. 2
   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. 3

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

4. 4

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

5. 5

   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.
