When Reneé Fishman needs to release stress, she doesn't get a massage or take a bubble bath.

She gets on a trapeze 23 feet above the ground.

"It's very liberating to be able to fly through the air like that. It gives you a little bit of a rush," says Fishman, 34. "Each time you go up the ladder and step off the board, you're in the air for a brief time, but it makes an impact."

Though Fishman lives in Manhattan, the real estate broker says she travels to Long Island to take classes with I.Fly because she likes that the school is run by two brothers, and that gives the sessions a family atmosphere. "They make it a fun time," she says.

About the school

I.Fly is run by Anthony Rosamilia, 31, a former Club Med circus act and trapeze instructor who lives in Farmingdale, and his brother Marco Rosamilia, 32, who lives in Manhattan. The school lost its Smithtown home last season after noise complaints about music from neighborhood residents, but reopened this month for its fourth season in Rockville Centre. Lessons continue through October.

Why fly?

Flying builds self-esteem, says Anthony Rosamilia. "It's something you're challenging yourself to do. Nobody can get up there and help you do it. It's totally up to you."

Flyers are attached to ropes that are held by instructors on the ground, and are above a safety net, he said. A typical class begins with students grabbing the bar and practicing techniques while swinging, followed by the opportunity to be "caught" by an instructor swinging from another bar.

"You'll never forget that first time you're flying on a trapeze," says Rosamilia. "To be able to create a memory in somebody's life is pretty amazing."

For spectators, it can be entertaining watching first-timers psyche themselves up to make the leap, he says. Some people scream, but not too many. "You're scared, but you're not really scared," he says.

Who can fly

Rosamilia says the school has had students of all ages - as young as 4. There aren't any upper weight restrictions. "If you're someone who is willing to get up there, our staff is experienced enough to make it happen," he says. Classes are scheduled according to demand - including four- to six-week workshops. Upcoming sessions are listed on I.Fly's Web site.
