Bicycle crunch
From Wikipedia, the free encyclopedia
A bicycle crunch is a form of abdominal exercise. The exerciser lies on his back, placing his hands behind his head for support. He bends his knees 90° and then alternately raises his legs to bring his right elbow and left knee together and then left elbow and right knee together, resulting in a leg motion that resembles pedaling a bicycle. In the past it has been considered risky due to the stresses it places on the body, particularly by causing compression of the cervical disks in the neck, but when performed slowly and without pulling too hard on the head it is safe to do.[1]
Analysis using electromyography has shown the bicycle crunch to be one of the best forms of abdominal muscle exercise.[2]
