In the past when I was first learning We trained this way. But i was a teenager then.
we would actually spar and do chi sau on table tops. Not really like in the movies...but what ever was avaiable...
At a local park they would have heavy park tables with benches we would fight on.
We werent intent on pushing someone off..Just getting in alot strikes an controlling or movement and manurervaing as to not fall off.
But we like teens then. thinking we were invincilbe...So the idea of real damage that could have happen to us we didnt take into consideration...I mean me an this one guy would fight on walls, on beams, on steps, on tables, on stages, in the grass, in the rain, in the snow, at night, etc etc...It was something we did all the time at any given place...we looked for new places to fight...We didnt implent throws and take downs on the benches and tables but we did do some pretty hard sparring in those days.
now i just do chi sau with a buddy of mines on a elevated sewer cover...its about two feet off the ground maybe a little more...its about four square feet no more than five.
