It's the fastest-growing dance fitness program, and it's winning over the world! 

BollyX is a Bollywood-inspired dance class combining choreography and hot music. 

The 50-minute mix of high and low interval cardio will get you moving, sweating and smiling.

"The music brought me in," said 60-year-old Carla Riffel who tried her first BollyX class two and a half years ago with no experience. Now, she's hooked. 

"It's just follow-the-leader," Riffel said. "It's not about being perfect, it's about having fun." 

It's fun and efficient. BollyX is a legit calorie burner because you really don't stop moving. It builds strength, endurance and confidence. 

"It helped me unleash my inner rockstar," said Swapna Bolisetty. "I get more comfortable when I go on the floor to dance."

Even the Sharks got in on the action. Last year, the BollyX workout was featured on ABC's hit reality show "Shark Tank."

"You don't even feel like you're working out because you're having so much fun," said Micki Stary, Director of Group X classes at 24 Hour Fitness.

So, if you're ready to shuffle outside the box and embrace your inner Bollywood, grab some sneakers, water, an open mind and get shakin'! 

BollyX classes are available in over 100 cities worldwide, and over 3,000 instructors have been trained to lead these classes. New this year: BollyX on Demand. So you can stream over 250 dance routines on a laptop, TV or phone.
