Re: Ukemi on plywood?
If your ukemi is good and you think it is, then it probably isn't good...unfortunately. It's easy for people to think their ukemi is good in the dojo. But the truth is, you can teach a brand new student how to comfortably breakfall on mats in one or two classes. Ukemi is not the art of falling, it is the art of staying alive. If you're head is being launched at the concrete, the last thing I'm going to do is let myself be thrown, I'm going to figure out how to drag nage down(realistcally, not in practice). Anyway, by all means practice on hard surfaces. If you can roll with some roundness, it won't hurt to much. Just keep practicing.
