Around 7:00 and beyond - he’s talking about educating uke to move properly to learn the throw. To not resist by hunkering down but to accept the tilt forward. Then he describes making contact not hip to hip, not shoulder to shoulder, but tori should aim their shoulder blades to Uke’s hip. This isn’t how seoi nage will always play out, but gives tori the right aim against uke during drilling. EDIT: correcting time stamp
Absolutely love this guy, the way he teaches and his massive knowledge of Judo makes it so you don't even need to know French to get something from his videos.
Many smb could give me some ideas about understanding what sensei Katanishi want to explain when he falled through uke (who is in high parter)? Thanks! (Time: 7:43)
