In a Gym start from the power position with you back foot on a line. Spread the lift leg out to a point which is where you land with that foot on the same line toe pointing forward slightly. You could use a towel in this drill. Have a player kneel infront on the line with his glove held forward at knee hight. You willcome forward and hit the gys glove with the towel and rotate you hips through. Your lift foot will rotate to point at HP. Your rear leg will lift high and rotate to a squared up feilding position, head down and do not try to stand up too soon. Accentuate the move. Be deliberate and repeat over and over.
Very important to keep feet in alignment on the line and hips steady untill rotating forward. Throwind elbow and clove elbow start at parallel position like a scarecrow and do not wrap throwing sholder back . Straight line front to back.
