Like to climb walls? Enjoy testing yourself and your body? How do you feel about trampolines and the NBC series American Ninja Warrior? If those questions tripped your need for adventure, there's a place for you. Opened in 2015, North Miami's Ninja Lounge includes 40,000 square feet of space — a full quarter of that covered by trampolines. About 20,000 people use it each month — and 5,000 to 8,000 on "a slow weekend," says marketing manager Jessica Albert. There are three basketball hoops, two dodgeball courts, and an elevated ropes course. The main attraction is the ninja warrior obstacle course, a replica of the consistent features of the course used in the Ninja series. (It is also the only gym in South Florida certified by the show.) The place costs from $10 to $54.50 per hour, and monthly memberships start at $49 per month. There are also creative fitness classes, including ninja warrior boot camp, ballroom dancing, and hip-hop. "We get a lot of people training for the show," says Albert, who lists athletes such as former Yankees catcher Jorge Posada and NBA star Dennis Rodman among clients. "There's even a diner where you can eat after you work out," she says.
