SkyMania Trampolines' general manager Nancy Burritt believes she's found a formidable tool to fight childhood obesity: the trampoline. Jumps and flips atop its springy surface fuse excitement with a heavy dose of exercise, melting away pounds without the mini-humans even noticing. But it isn't just children that gain slimmer physiques and a newfound respect for kangaroos amid SkyMania Trampolines' 9,000 square feet of wall-to-wall trampolines and foam pits. The facility plays host to everything from corporate team building to graduations and bachelor parties. "Our main goal is to give people a safe place to spend an evening and have fun," Ms. Burritt says.

This commitment to fun leads the staff at SkyMania!—many of whom have lost weight themselves—to incorporate traditional sports and exercise to the trampoline-filled environment. They host dodge-ball tournaments and lead volleyball matches. SkyRobics, one of the more popular classes, incorporates weights, bands, and mid-air fist bumps into a low-impact workout. Though the activities are diverse, Ms. Burritt thinks each one accomplishes a shared goal: "To make people happy."
