Re: Ukemi on plywood?
I was at a seminar recently where there was no mat for the last session. Some people were still crashing into the floor without modifying their ukeme!
Perhaps some Aikidoka think they have to be macho during both technique and ukeme (the I'm hard syndrome) and are not really considering how to protect their body. IMHO ukeme should be the same no matter what the surface i.e. safe.
