A-skips are similar in motion to marching in place with a little more bounce, almost like you are skipping in place. Focus on controlled motion and raising your knee above hip height. Arm drive is more active than the marching motion. As motion is mastered, pick up the tempo. Key points: Your elbows should be at a 90 degree angle. Make sure not to cross the midline of your chest as you drive your arms in the movement.
