We did the arm-roll thing last week for the first time. I appreciated the opportunity to do it from a kneeling position first.
I hope to go the dojo during free gym to practice, since I'll be off from work on Tuesday.
I think it will be as important to learn correct falling as it will be to learn correct technique.
And hey! I'm one of those off-beat female-type looking persons who gets a lot out of the physicalness of falling and rolling. Haven't done much of it in the last twenty years, but I can get caught up now...
