Its hard enough trying to explain to people what a bboy or bgirl does or what they're relevance is in the spectrum in hiphop, but when I see things like this...it hurts my feelings. Teaching people dance moves in which they can exercise, being healthy, and feeling good about themselves is a cool accomplishment few people can do well.
I know few bboys/bgirls check out my site and this is for you guys. If you see this 'Mario The Trainer' please feel free to show him how he's doing it wrong. The take his class of middle-aged moms out for ice cream.
