Koko FitClub Smartraining system, which debuted in Entrepreneur magazine's 33rd annual Franchise 500 rankings, gives patrons personalized control over their own fitness with 30-minute custom workouts at automated stations. Each person's tailored regimen begins with a body-composition test, which helps trainers to build a program based on weight loss, toning, or whale-wrestling goals. Staff members then load workout plans onto the client's Koko key, which plugs into Smartraining machines. The workout equipment greets guests by name and instructions steer limbs through a medley of strength and cardio maneuvers, all of which take place at a single station. Because the system stores each visitor's progress, workouts adapt daily to keep muscle groups from starting a fight club out of boredom. A personal website tracks fitness data for at-home viewing.
