Hollywood and the sunset strip are known worldwide for their nightlife. Now there's a new hotspot for song and dance and no VIP line outside. No bar inside either, unless you count a juice bar.

Welcome to Cardioke where karaoke and fitness go hand in hand.

It's the brainchild of Billy Blanks, Jr. and his wife Sharon, a couple who have spent years on stage and on the fitness floor.

"We have both been performing professionally for over 15 years or so. On Broadway."

"We wanted to find a way to make fitness fun."

"People love to go out and go to dance clubs and go out dancing. They love to sing in their car. So we were like how can we combine all those things people like and make it an actual workout."

"It's not like exercise. It's fun. If you don't like to go to the gym and you don't have time, it's fun."

Each class begins with stretching, abs and a few warmup steps.

Then it's showtime.

"Everyone has a dancer or singer inside and this is a good forum to let that inner entertainer out."

"Ms. Desiree, believe it or not, used to be tremendously shy. When the dance circle would start she would say oh no don't take me in. But now she is a show off!"

You can make song requests, but unlike typical karaoke nobody's singled out. Everyone sings together.

Billy likes to make you try to do the impossible. Of course once in a while you lose your footing. But you just have to bounce back and try it again.

You can find classes offering disco, country, even 80s cardioke. They come with the armbands and the legwarmers. Oh yeah, we go there!

And if you prefer to sweat and sing in the privacy of your own home, there's a cardioke DVD.

"so many people are left out of fitness. So i wanted something that literally went no, come in."

"it kind of has that atmosphere, the club-like atmosphere, with the lights and the darker room and the dance music going, but you don't have all those gross people trying to hit on you. So it makes it a little nicer."
