A 63-year-old man does double back flips on the trampoline. Nearby, a 56-year-old woman nails a cartwheel on a gymnastics beam. In the next room, a 42-year-old man practices for a movie shoot by "falling" off a 20-foot-high scaffold.
"All you're seeing is an old guy having fun," said Jim Grindeland, 49, of Eagan, speaking for his peers at Gleason's Gym. Every Wednesday night for two hours of classes and "open gym," these middle-aged folks perform leaps and bounds with gymnasts who not only are young enough to be their children, but often are their offspring.
That's one of Gleason's recreational director Dave Kennedy's primary recruiting tools.
"I walked in here five years ago with my 12-year-old son, and Dave looked at me and said, 'I have got the class for you,'" said Rob Perry, 54, of Bloomington, who enrolled in a trampoline class.
Kennedy insists that the recruiting part is easy. "The trampoline just sounds fun," he said. "Fitness is a little bit more and more getting to be a factor for people coming. But I think mostly they've been looking for something different to do, something fun, something challenging."
The first challenge: Forget everything you ever knew. Perry's family had a trampoline in their Bloomington back yard, and he had mastered a forward flip. Or so he thought.
"They had to erase everything because no one had taught us the right way to do it," he said. But what he was taught at Gleason's about flips "doesn't take nearly the effort. When you do it right, it's easy.
"Anybody's body here can do any of this stuff. It's your brain that gets in the way."
