A balance/wobble board is a good way to improve balance, as well as stretch and strengthen ankles. It's also a great and fun way for small kids to develop their motor skills.
Here are some ideas:
Wobble forward and backward or side to side.
Try with your eyes closed.
Stand on one leg. (carefully!)
Balance a book on your head while wobbling.
Try all of the above (very carefully!)
Play catch with someone while standing on the wobble board.
Time yourself to see how long you can keep your balance without an edge touching the floor.
Common sense woodworking rules apply. Be safe, read and follow the safety guidlines in your power tool manuals, measure twice, cut once, etc…
