When students take a spin class at Any Body Fitness, they know they’re pedaling atop sleek, professional-grade cycles. That’s because the staff at Any Body Fitness contains more than just certified spin instructors; in fact, staffers’ primary task is to scout out and sell top-shelf cardio, strength, and aerobic equipment. The employees outfit everything from modest home gyms to sprawling commercial wellness centers with ellipticals, treadmills, and weightlifting benches. So, when they select the stationary bikes that instructors use to punch up spinners’ heart rates, they do so with a solid understanding of the industry. Personal trainers, nutritionists, and active-lifestyle mentors act as equally knowledgeable resources for clients seeking wellness help outside of spin class.
