Air Bike

The air bike is a cardio exercise that works your whole body. Here are the steps to do it:

1. Lie on your back with your legs straight and your arms extended over your head.

2. Lift your shoulders and legs off the ground and bend your knees and elbows slightly.

3. Bring your right elbow and left knee toward each other while extending your left arm and right leg.

4. Switch sides and repeat the movement with your left elbow and right knee.

5. Keep alternating sides as fast as you can without losing form.
