A Flatiron District gym has turned the stationary exercise bike into a cutthroat, high-tech tool for fitness. NY1's Health reporter Kafi Drexel filed the following report.

Spinning just picked up a bit more inertia at Flywheel Sports, a new cycling studio in the Flatiron District co-founded by former Giants running back Tiki Barber and indoor cycling veteran Ruth Zukerman. Besides the celebrity backing, these exercise bicycles have new technology to help take an average workout to another level, such as monitors that show calorie expenditure and resistance levels.

"We've never been able to do that before," says Zukerman. "I have so many riders come up to me after class and say, 'I don't understand. It's been five days a week and my body is not changing.' Of course, we talk about nutrition and what goes in their mouth, but the other part of it is, what are you doing on that bike? How hard are you really working?"

Individual data gets stored and riders can check in on their performance after each session on the studio's website. Riders can also choose to display their data on "TorqBoards," large flat screen televisions that show rider profiles, video and ride leaders during classes, which can throw a bit of competition into the mix.

"I need to see cadence. I'm training for other things in sports, so that's all the data I need," says rider Jesse Pasca. "And it makes it so much easier and it makes it a choice to go to."

"Really, it is a way to do your personal best by seeing what other people are doing," says rider Robin Hoffman. "Because you know that I look around sometimes in other classes, and I see people who don't have resistance on and they are doing things and I know they're not getting the kind of workout they need to. They're really wasting their time."

As they develop a lust for competition, riders can also benefit from the studio's design. The tiered, stadium-style seating gives instructors and students improved vantage points and communication.

"I've been in studios with so many bikes on the same level and people would come up to me and thank me for the class at the end and I didn't even know they were in the room," says Zukerman. "So with the stadium seating, I can see every person. I know if they're working safely, and if they're not, I just scoot over there and correct their position or whatever needs to be done."

Flywheel's classes start out at $30 per individual ride. For more information, visit www.flywheelsports.com.
