HOW TO DO BICYCLE CRUNCH
- Lie on your back with fingertips lightly beside your head and hips and knees bent.
- Curl your shoulders up, rotate one side of the rib cage toward the opposite knee, and extend the other leg; switch sides in a smooth pedaling rhythm.
- Keep the neck relaxed and lower back controlled against the floor.
