More than 20 years ago, two lifelong friends decided to team up and put their minds (and their muscles) to good use. They opened a martial-arts school in an Ottawa suburb and haven't looked back since. And why would they? One half of that team, Tony Greco, grew to be one of the country's leading fitness professionals. Today, he and partner Paolo Fiorin continue to turn their original idea into a thriving business as well as a comprehensive training philosophy.
