Jillian Cooney, who has been a member of this sports club for 4 years, enjoys the spinning class. But these days, she says, the group exercise is a little different.
"_________________________________. I would necessarily say it's more difficult, more challenging. I challenge myself more with these levels than when I use the resistance."
The sports club's stationary cycles were recently retrofitted with so-called "Green Revolution" technology, which turns every bike into an electrical generator. _________________________________.
Mike Curnyn is with the Green Revolution, a company based in the eastern U.S. state of Connecticut. "We put a generator on each bike in the group cycling studio so while the fitness enthusiasts are getting their workout, their energy is being captured and being converted to clean electricity _________________________________."
