At Embassy

Granted i was very late for class. Again. Friday is just not working for me, is it? Anyway, in the last half that i attended we did gyaku-hanmi katate-dori kokyu-ho, then ryote-dori kokyu-ho (omote and ura) and finally ryokata-dori kokyu-ho (omote and ura). I understand am not the only one with a slight discomfort in the back due to our ukemi on hard floors. Any remedies?
