Funny you should bring this up.
I don't think I have the greatest ukemi, but its passable. I've learned to relax and just go with the flow. And it generally works.
Then tonight. Not once, but twice. I posted my arms out.
Both were slow falls. I let a newer guy throw me during randori. He went for a kataguruma, and I went over fairly slow, and for some reason I stuck my arm out. It created sort of an armbar effect. Didn't feel nice at all.
Then, not long after....different partner drop seoinages me. I post out my arms.... shit hurt. Alot. I continued to roll kind of, and ended up only bending my wrist, and mostly my fingers( bending past how they bend ).... but my hand is a lil beat up now. Could have gone alot worse on either of them though.
Both falls were kind of slow, delayed action... I think if they were faster I would have just gone over with no issue, but being slow, for whatever reason, my brain decided that I should stick out my arm.
Moral of the story. DO NOT stick your arms out to stop the fall.
