Any gym can have free weights and treadmills, but Fit 24 thrives on a strong sense of community. The gym’s trainers host nonstop group fitness classes five days a week, including classic aerobics and boot-camp sessions that blend cardio and strength training. Trainers can also set up personal-training sessions, during which they teach clients to make the most of the gym's perpetually available equipment. Trainers can even go mobile to bring their expertise to the front doors of nearby homes and offices to keep the sweat flowing. For competitive customers, the staff organizes flag-football and kickball teams, which compete in six-week seasons against other local teams. After working up sweats, gym members can hit the free tanning beds to maintain their summery glows throughout the depths of winter or in the event that the sun never rises again.
