If you’re a martial artist, then you do drills. And, if there are drills that you do, you should, at least once in a while, you should do them impaired.
Could you fight if you were injured? If one or both arms were broken, slashed or incapacitated? What if you had an injured foot?
Here’s a little drill you can do impaired — work your slip ball. Do a round with one arm tied up, then a round with the other, and then a final round with both arms tied up. Just put on a belt loosely enough to slide your hands in and out with relative ease.
If you feel froggy, do another round with a rock in your shoe (Mark Hatmaker calls that the tenderfoot drill).
