Slim and full of energy, Kathy Bartnick's present-day physique betrays no hint of her lifelong struggle with weight. Five years ago, she shed her excess pounds through exercise and proper nutrition, and today she works to teach others the same determination. She heads up a team of expert coaches, who lead students at all levels of fitness through energetic group workouts. They also give clients meal plans and nutritional tips, teaching them how to whip up a wholesome snack and differentiate between a healthy vegetable and a fire hydrant dressed in a carrot costume. In lively cycling classes, clients peddle away on advanced Star Trac bikes as upbeat music plays and a glimmering light show takes place before their eyes.
