Medicine Ball Crunch

Description

How to Do Medicine Ball Crunch

1. 1
   Setup

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

2. 2
   Setup

   Hold a medicine ball with both hands, either pressed against your chest for less resistance or extended overhead for increased difficulty.

3. 3

   Brace your core, exhale, and slowly lift your head, shoulders, and upper back off the floor by curling your torso towards your knees.

4. 4

   Focus on contracting your rectus abdominis, ensuring your lower back remains pressed firmly into the floor throughout the movement.

5. 5

   Inhale as you slowly and with control lower your upper body back to the starting position, maintaining tension in your core until fully reclined.

Tips

• Maintain a neutral neck position by looking towards the ceiling or slightly forward, avoiding pulling on your neck with your hands if they are behind your head.
• Control the movement both during the concentric (lifting) and eccentric (lowering) phases; avoid using momentum to lift your torso or letting gravity drop you back.
• Engage your transverse abdominis by drawing your belly button towards your spine before initiating the crunch to enhance core stability and support.
• Vary medicine ball placement: holding it overhead increases leverage and difficulty, while holding it at the chest reduces the resistance.

Common Mistakes

• ×Arching the lower back during the crunch reduces abdominal engagement and can strain the spine; ensure your lower back stays pressed into the floor.
• ×Using momentum to "throw" your body up instead of controlled muscle contraction diminishes the exercise's effectiveness; slow down the movement and focus on a deliberate abdominal squeeze.
• ×Pulling on the neck with your hands can cause neck strain; keep your neck relaxed and let your core do the work, or place hands lightly behind your ears without pulling.
