A standing practice to get those feet moving. Tap the ball with the toes of each foot moving to the side of the ball slightly in front. Then tap the ball with the foot furthest away behind the standing leg. Then work your way back across repeating the motion. Try to keep the ball still and just move the body building up speed and rhythm.
The ball mastery practice works around one cone in a "V" shape. Bring your foot across your body on top of the the ball moving it towards you. Touch out with the outside of the same foot and repeat with the other foot. Work both sides equally and don't forget to rotate your body.
