Re: So where is your weight?
I've found that if I open my hips and can stay relaxed, that my weight just naturally falls on my opponent.
If any part of my body becomes tight or "constricted", that part starts to behave as a separate unit and its weight does not get added to the overall equation.
So, in the end, I don't really put it anywhere.
I am without any world titles, so not really sure how effective this is, but people can feel it and tell the difference between "on" and "off."
