A great thing about doing stationary dribbling drills, is that they can be done pretty much anywhere that you have a hard flat surface. So whether you use your driveway, garage, or a sideline while others are playing on the court; you have space needed to work on your handles.
The windshield wiper reverse between the legs dribbling drill is going to help you develop quick hands, and work on ball control. It combines the traditional windshield wiper dribbling drill, with a reverse between the legs move. This is also a great drill to use in a camp setting, because it only requires one ball per player, and doesn't require much space.
