To perform a set of abdominal air bicycle:
Lie prone on a mat with your hands behind your head, knees bent and feet in the air. Your trunk should be in a neutral position to start.
Raise your chest off the ground and twist the top of your trunk to bring your right elbow toward your left knee. At the same time, straighten your right leg without resting it on the ground. Remember to breathe normally and maintain a neutral lower back position throughout the entire movement.
Keeping your chest in the air, bring your trunk back to the neutral position and return your legs to the starting position.
With your chest still off the ground, twist the top of your trunk to bring your left elbow toward your right knee. At the same time, straighten your left leg without resting it on the ground. Remember to breathe normally and maintain a neutral lower back position throughout the entire movement.
Repeat steps 1 through 4 until you have completed the desired number of abdominal air bicycle repetitions before resting your chest and legs on the ground.
This completes one set of abdominal air bicycle.
