Sure, I think some topics of conversation could be:
using ones own weight
the role of breath
the opponents weight/mass
from there i think it would be appropriate then to move on to push tests, or simple waza.
Would anyone like to discuss some of the above?
I'm game, but I think focusing on a simple task that can be done both ways and have the differences in each method described fairly easily would be less prone to going off in the weeds. Probably best to start a new thread though.
