How do you do the 5th sotouke ( The leg sweep move ) without bending your back or comprimising your stance ?
Take the tension off the rear leg slightly and
pull back using the left hip as you unweight the right leg - I come back to almost Neko-Ashi Dachi at about 455 degrees before starting the scooping block/deflection with the right arm while dropping deeper instance prior to completing the scooping action and the turn to 90 degrees while extending the other hand like a fist and simultaneously rising in stance as you drive forward off the left rear leg and complete the right arm Soto-Uke.
Don't know if any of that was intelligible - very hard to describe transitional movements IMO - but I think it's trying to analyse these sort of things that helps develop "quality" Karate - and is essential for good Insructors.
I think the key is transitioning through the "Neko-Ashi" and not completing the full 90 degree direction change...... what about the rest of you ? - how do you do this transition ?
