Great Video
Unfortunatly, it was so good I have a couple of technical questions \ comments, based on the way we (My Sesnei teachs us how to guide too) teach those Ukemi:
A. For the Ex. demos, What is your non leading arm doing while rolling? Are you trying to block with it (Our approach considers that to be a risky solution).
B. For the last Breakfall, why are you crossing your legs? (My expreince is this can become painfull if the fall is strong and the upper leg goes with the momentum.
And again, great work.
