Thank you for posting this, Yamaguchui Shihan rocks! This is an excellent demonstration !
While I think it falls short of practical application to a combat scenario, it still provides the experience of the "pucker factor". Far from the " oh shit pucker factor" yet, " it ain't working ", so, adapt and redirect.
Again, thank you.
It shows if you're using your whole body or not. You should still be able to move uke while relaxed. Actually it should be really difficult unless you're relaxed!
You are absolutely correct, Uke is a dojo component, not a real-life opponet. Dojo ballerinas will dance for you no matter how badly you play.
