Hello. I am trying to improve my left hand and drives/movements to my left. I am good for now with my right, but really suck at my left. What can get me better at both? Also, I want to be able to have an effective crossover. What should I do about that?
Yes only thing to do is practice, i used to have same problem but practiced everyday until I finally got some results. Check out the Power Dribble, at www.powerdribble.com its a great training aid to help you get stronger and faster with your dribble. Can even use one on each side at the same time. I have used it before and can definetely tell it is working your arm and forcing you to dribble correctly.
Hope it helps, good luck
"I am good for now with my right, but really suck at my left. What can get me better at both, other than to keep practicing with my left and going on the left side?"
All you CAN do is practice and if that isn't good enough for you then good lucking going anywhere with basketball..
