    How to: Crunch (arms straight)

    1. Lie flat on your back with your legs bent at a 90-degree angle.
    2. Extend your arms straight above your head.
    3. Engage your core and lift your upper body off the ground.
    4. Keep your arms straight as you curl upward, focusing on contracting your abs.
    5. Slowly return to the starting position and repeat.

    Common Mistakes

    • Pulling on the neck with hands.
    • Relying on momentum instead of controlled movements.
    • Not engaging the core sufficiently.

    Modifications

    • Perform with bent knees to reduce strain.
    • Use a stability ball for added support.

    Tips

    • Keep your chin tucked to avoid straining your neck.
    • Engage your core before lifting to maximize muscle activation.
    • Control your movement to prevent using momentum.
