You have most likely heard of the ball handling drill called pound dribbles where you simply dribble the basketball with one hand as hard and as quickly as you can for 20-30 seconds. Well for this drill instead of just pound dribbling the basketball the whole time, you are going to add in a double crossover move. That way you can make the basketball drill a little bit more difficult, but also work on going from dribbling the basketball to quickly making a combo move.
The pound dribbles double crossover dribbling drill is going to help not only develop your handles, but it will also work specifically on the double cross move. When you do the drill make sure that you are visualizing the defender in front of you when you do the move. Really sell the double crossover move with your eyes, body, etc. that is going to be the key to getting your defender to fall for it.
