6 things players can do on their own:
1 - Watch Games - plenty of platforms allow you to re-watch recent games played (ESPN + / NBCSN Gold / Bleacher Report).
2 - Youtube - Great resource to find highlights, find even whole games and exercises you can do on your own.
3 - Play FIFA - It can actually help you become a better decision maker!
4 - Use the sessions and instructional videos provided on the WSA site and gte practicing!
5 - Be creative and create your own challenges! Can you hit a water bottle on top of a wall? Or hit a ball into a garbage can? Use a partner (sibling) and see how many times you can pass the ball back and forth through the air without dropping the ball. What can you come up with?
