I found taiji works very well when on the floor.
You can still stick to them and by neutralising their weight through the body, and into the ground, offset their technique.
If they can't get their centre of gravity where they need it then they can't apply their technique.
Its good fun.
I used to play this like a game with my first teacher when I was much younger - my force used to fall through him and he would discharge from his chest or stomach and shoot me up in the air!
I don't know how he did that - but it was great fun at the time. I'd be coming back for more all day if he'd let me
Nostalgia aside.... what I am saying is that a lot of the principles work lying down.
