I know lots of people who probably train eight hours a day. The trampolines that Cockburn and Tourgeon train on aren't your rinky-dink backyard variety though. Although trampolining might seem dangerous, Tourgeon claims it's not, despite the fact that they perform their routines at heights of 25 feet and more. You do everything by the book. Follow the rules and you don't get hurt.
Injuries are very rare, and usually are only a sprained ankle.
Cockburn and Tourgeon met 10 years ago in the Richmond Hill gym where they train. Although they put in as many hours training per week as most people do at full-time jobs, Tourgeon says he and Cockburn still have time for their school studies and each other. Mostly it's life stuff.
