The best way to improve hand-eye coordination? Well boy do I have the answer to that question, i've been waiting all my life! I have a couple, the first few being quite obvious : darts, balls to the wall, playing the knife and finger game, writing blindfolded and many more. They all really bring something to the table, be it some basic motor functions, but also knowing how to react under pressure and with some adversity. Though these are nice, the one TRUE goat technique that i've mastered over the years : the crêpe flip. Now I know what you'll say, that this is ridiculous, but have you ever nailed a triple backflip 360 spin pancake flip? Now that takes dexterity, skill, timing, and mental fortitude to be able to plan, visualize and execute, all things that go into hand-eye coordination, and its been the secret success sauce behind my breakout seasons and something i'll keep doing daily to stay sharp and always have an edge over my opponents.
