repetitive separation kick exercise

Ideally, chasing the ball is unnecessary. If you don't stay in your three foot circle and maintain  constant rebound height (and placement), what usually happens is what you see in the video. You chase the ball!

Despite the chase, this practice tests balance and rooting. On a good strike, sense the pointed toe of the kicking foot, formally named the separation kick. On a good strike, sense the relaxation in the body. The shoulders sit in their girdle; the weighted foot stands immoveable. The hands could move to any position to connect with another's opposing arms. While the groin muscles and the hamstrings stretch, the quads continually contract.  This is a great exercise that comes in handy if in push hands you both agree to use the feet.
