Born as the Greentree Racquet Club, Greentree SportsPlex underwent extensive renovation to emerge as an 80,000-square-foot, multi-sport facility. Free weights, kettlebells, and Legend Fitness weight machines line the bright red walls. Meanwhile, a batting cage comes in handy during onsite lessons that cover the fundamentals of playing baseball and softball, as well as surviving the uprising of pitching machines. During boot camps, instructors lead their groups through obstacle courses, core work, and whole-body exercises on the indoor turf. They also motivate clients during personal-training sessions and group fitness classes, including Zumba dance aerobics and spinning sessions set to energy-packed music.
