After training clients for 15 years in outdoor boot camps, Mac Cassity finally figured out how to control the weather. He yearned for an improvement over sessions that were dictated by capricious rain, stifling heat, and the never-ending nuclear winter rather than by their instructors. So he moved the whole operation inside, transferring his campers and his 60-minute routines inside, where padding and various exercise equipment provide engaging and effective workouts.

Mac's one-hour sessions rely on positive encouragement and teamwork to motivate students, who forge strong social bonds in their quest for fitter physiques. The classes sync partner work and exercises that leverage body weight and utilize fitness equipment to burn off fat and build muscle–all to the beat of invigorating songs.To keep the slimming, toning programs lively, Mac holds contests for weekly and monthly prizes to provide extra incentive for patrons to drop unwanted pounds. For a more tranquil athletic approach, the center also hosts yoga classes that help students strengthen their cores, boost their flexibility, and center their minds.
