Crunch (arms straight)

Description

How to Do Crunch (arms straight)

1. 1
   Setup

   Lie on your back with your knees bent, feet flat on the floor, and hip-width apart. Ensure your lower back is pressed gently into the floor.

2. 2
   Setup

   Extend your arms straight up towards the ceiling, keeping them parallel to each other and your palms facing forward or inwards.

3. 3

   Exhale as you slowly engage your abdominal muscles, lifting your head, shoulders, and upper back off the floor. Keep your arms extended towards the ceiling throughout the movement.

4. 4

   Focus on drawing your navel towards your spine, crunching your rib cage towards your hips without pulling with your neck. Lift only until your shoulder blades clear the floor.

5. 5

   Hold the contracted position briefly at the top, then slowly and with control, inhale as you lower your upper body back to the starting position.

Tips

• Maintain a consistent gaze towards the ceiling to help keep your neck in a neutral position, preventing strain.
• Focus on the mind-muscle connection, actively squeezing your rectus abdominis at the top of the crunch rather than just going through the motions.
• Control the eccentric (lowering) phase of the movement, resisting gravity to maximize muscle engagement and build strength.
• Keep your arms locked straight and fixed throughout the movement; avoid swinging them or letting them bend to maintain tension on your core.

Common Mistakes

• ×Pulling on your neck instead of engaging your abs strains the cervical spine; fix this by keeping your chin slightly tucked and imagining an apple between your chin and chest.
• ×Using momentum to lift your body reduces abdominal activation; fix this by performing the crunch slowly and with deliberate muscle control.
• ×Lifting too high, turning it into a partial sit-up, takes tension off the rectus abdominis; fix this by only lifting until your shoulder blades are just off the floor.
