What sport is better for hand-eye coordination – juggling or ping pong?
I love to juggle in particular and see the competitions on ESPN. Juggling is much better for hand eye coordination. Tennis teaches you to focus on an object, but juggling teaches your mind to concentrate on multiple objects in the air. This is only limited by the number of objects you can juggle. Once the level of juggling 7 balls have gotten a really special skill that not many people in the world can say they have. Juggling also teaches you how to be ambidextrous. If you are doing tricks like the back of crosses, you need train both arms to do the trick on both sides. Studies have also shown that juggling increases brain mass. Hope that helps.
