Lie on your back with your knees bent and feet flat on the floor.
Ensure your legs are hip-distance apart.
Place your hands beside each ear with your elbows dropped to your side.
Tighten your abdominal muscles and perform a sit-up, bringing your chest up towards your thighs.
As you sit up, rotate your body, bringing one elbow to its opposite knee.
Control the movement as you lower your body back down, and then repeat, bringing your other elbow to its opposite knee.
