- Take a lunge stance position: one foot forward with the knee bent, and the back knee an inch or two away from the ground. Shoulders should be slightly in front of hips.
- Jump up, extending both legs.
- Switch legs in midair, bringing the back leg to the front and front leg to the back.
- If you're a beginner, don't switch legs in midair. Instead, start in a standing position with feet together, then jump and land into a lunge. Then jump back into standing position. Alternate legs.
