Start by lying on your back onto a mat with your hands behind your head. Keep both legs straight about one inch off of the floor. Immediately raise one knee (your choice) up to the elbow of the opposite side and try to touch your elbow to that knee. Repeat this step with your other knee and elbow for as many repetitions as you can. The idea is to execute the movement in a smooth and controlled fashion so as to simulate riding a bicycle while lying on your back. Be sure to concentrate on having your abdominals do all the work!

Muscle group: Abdominal

Steps
