Build explosive dribbling power and a low, controlled handle. Pound dribbles train the fast-twitch response that makes every move sharper.
In an athletic stance, pound the ball as hard as you can at ankle height, then knee height, then waist height. Repeat with the weak hand. Keep the ball directly under your shoulder.
20 pounds per height level, per hand. 3 sets.
Add a defender shadow. Then pound with eyes closed to develop feel. Finally, pound while shuffling laterally.
