This is a progression on the A March; start by practicing the marching postures if needed. Begin hopping on one foot, keeping the hip extended with a strong glute. With the other leg, perform the A march shape, driving your foot down the ground under your hips. Keep your core strong, using the rebound of your leg off the ground to bounce it into the A march shape more than pulling your leg into position. Once you feel comfortable with the movement, you can progress by traveling forward.
