    How to: Straight Leg Sit-up

    1. Lie flat on your back with legs straight and feet together.
    2. Place your hands behind your head or crossed over your chest.
    3. Engage your core and lift your upper body towards your knees in a controlled motion.
    4. Lower your torso back down to the starting position without letting your feet touch the ground.

    Common Mistakes

    • Using momentum rather than engaging the core.
    • Not keeping the back flat against the ground.
    • Pulling on the neck while lifting the torso.

    Modifications

    • Bend your knees if you struggle to keep your legs straight.
    • Use a mat for cushion if performing on a hard surface.

    Tips

    • Keep your legs straight and avoid bending your knees.
    • Focus on using your core to lift your torso.
    • Breathe out as you lift up and inhale as you lower down.
