Triangle Flip Flop Drill

The key to improving is to get out of your comfort zone and force your body and mind to adapt.

Start holding one ball in front of you with your right hand, and one ball behind your back with your left hand.
Dribble the front ball with your right hand, while flipping the back ball a few inches into the air with your left hand.
Very quickly switch your hands from back to front, so you receive the front ball with your left hand and catch the back ball with your right hand.
Repeat, switching your front and back hands continuously while dribbling the front ball and flipping and catching the back ball.

Don’t be afraid to look silly or make mistakes.
Make it harder: As you improve, run the drill faster to really challenge your dexterity.
Make it easier: Dribble the front ball higher and slower to give yourself more time to switch hands.
