    How to: Weighted Leg Extension Crunch

    1. Sit on a stability ball with your feet flat on the floor and knees bent.
    2. Hold a weight plate or dumbbell against your chest.
    3. Lean back slightly while keeping your feet planted and your core engaged.
    4. Extend your legs out in front of you while simultaneously crunching forward, bringing your torso towards your thighs.
    5. Return to the starting position with control and repeat for the desired repetitions.

    Common Mistakes

    • Arching the back instead of maintaining a neutral spine.
    • Using momentum instead of engaging core muscles.
    • Not fully extending legs during the exercise.

    Modifications

    • Perform without weights for beginners.
    • Use a smaller stability ball for better balance if needed.

    Tips

    • Engage your core throughout the movement to maximize effectiveness.
    • Keep the movement controlled, especially when lowering back down.
    • Ensure that your lower back is pressed into the stability ball for support.
