    How to: Frog Crunch

    1. Lie on your back with your knees bent and feet lifted off the floor.
    2. Bring your feet in towards your body, forming a 'frog' position.
    3. Engage your core and curl your shoulders off the mat towards your knees.
    4. Slowly lower back down to starting position.
    5. Repeat for the desired number of repetitions.

    Common Mistakes

    • Pulling on the neck with the hands.
    • Using momentum instead of engaging the core muscles.
    • Lifting feet too high, which can strain the lower back.

    Modifications

    • Perform the exercise with feet resting on the ground instead of lifted for more support.
    • Reduce the range of motion if experiencing discomfort.

    Tips

    • Focus on controlling the movement rather than rushing through.
    • Keep your lower back pressed against the ground throughout the exercise.
    • Breathe out as you lift and inhale as you lower.
