I do one [old jujutsu trick] where I am facing forward and the uke pushes me over backward from the chest. So I am bent over backward with somone trying to push me up and over at a 45 deg angle. Its looks impossible since I am already going over in agreement with the push.....I don't go anywhere, and when I bring myself upright it feels like a crushing weight on uke. Doesn't work without connection.
Works great in the real world in motion too. When grappling with them trying underhooks or trying to take your upper body over your feet or forward like a seoi-otoshi or seoi nage.
Please put up a video of you doing these things with Rob Liberti as your uke. Thanks in advance!
