    How to: Crunch (straight leg up)

    1. Lie flat on your back with your legs extended straight up toward the ceiling.
    2. Place your hands behind your head, keeping your elbows wide.
    3. Use your abdominal muscles to lift your upper body toward your legs, keeping your lower back pressed into the floor.
    4. Slowly return to the starting position and repeat for the desired number of repetitions.

    Common Mistakes

    • Pulling on the neck with your hands.
    • Using momentum instead of engaging the core.
    • Failing to keep the lower back in contact with the ground.

    Modifications

    • Bend your knees if straight legs are too difficult.
    • Perform the exercise with a smaller range of motion.

    Tips

    • Keep your back flat on the ground during the lift.
    • Engage your core throughout the movement.
    • Control the movement to avoid straining the neck.
