Segment of transcript of my karate class:
Instructor: Now I’m going to teach you how to do a rising block. Put your arm above your face like this.
Instructor: A little higher. Good. Keep those fingers in a fist. Now, before you switch and block with your other arm, you’re going to release the fist in the arm that’s already blocking and straighten your fingers, like this.
Me: Why do I straighten my fingers?
Instructor: Because after you block your opponent’s punch, you can grab his arm — try to hit me….
Instructor: You can grab his arm like this —
Instructor: — and twist it.
Instructor: Any questions?
Me: No, I think I got it.
