Bicycle crunch

Lie on your back with your hands behind your head and legs lifted. Bring your right knee toward your chest while twisting your torso to touch it with your left elbow. If you can, extend the opposite leg straight. Alternate sides in a pedaling motion while keeping your core engaged and lower back on the ground.

Easier variant
