This simple drill focuses more on your brain than on hand-eye coordination, but still trains your reflexes. The First part we describe here is only the base. Make it more difficult for yourself and you’ll gain a lot.
How to do it?
Kneel about one meter away from the wall
Put all balls in front of you
Place one box to your left and one to your right
Take one ball and throw it to the wall. Do not look down to see which ball you threw!
Catch the ball and check the number
Even numbers go in the left box, uneven numbers go in the right box
Try to improve the pace steadily
How to change the degree of difficulty:
Put e.g. red dots on even numbered balls, blue dots on uneven numbered balls
Add squares on even numbered red doted balls and triangles on uneven numbered blue doted balls
Change distance to wall
Try to increase speed, for example you can set a time limit
