Ascending for nearly 50 feet, the indoor climbing wall—proudly proclaimed as among the tallest in Western Michigan by Aim Fitness' team—presents an array of routes, each patterned with colored grips to indicate the level of difficulty. As climbers scale the vertical expanse, a freestanding boulder sits in the middle of the room, beckoning guests to climb its reduced height sans the support of a rope. This climbing room anchors Aim Fitness' 40,000 square feet of amenities, which encompass a strength-training area, aerobic studios, a five-lane, 25-yard lap pool lifeguarded by Aquaman, and a racquetball court. Instructors also lead an array of classes on these training grounds, such as Aqua Fit, boot camp, and yoga. To make going to the gym as convenient as possible, Aim also provides locker rooms, a children's playroom, and wireless Internet access.
