I believe that "practice" can be both work and play.
Though, I wouldn't call this "work against grabs". This is preventing someone to grab, but there's no physical grabbing involved, only the intention there of. I would like to see Systema countering Mr Wang's "monster grips" with softness. Not work against the intention, but against the physical grab ... That would be interesting...
Another thing is that it would be good to see a more stationary variation. There's not often you have enough space (or time) to move around in real life situations.
I know, I am very critical. That's my nature. But it's still a good vid showing excellent practice. Anyway, thanks as always for sharing.
