Haha, I can't dance, maybe it's my big Polish feet.
Seriously, the dances of the Caucasus are unbelievably magnificient. Fiery, graceful, wild and intricate, they capture the spirit of the mountains.
BTW there was a very real reason for all those squatting movements in Cossack dance. In Siberia, during the days of outhouses (or worse) if you had to attend to certain calls of nature, keeping still is the way for your bum to freeze up.
