Chas DeVetter, founder of DeVetter Fitness, always enjoyed helping people get in shape, so becoming a personal trainer was a natural choice for him. He knows that each client is unique, and they might require a different form of motivation, exercise, and nutrition plan to really get results. He and his trainers lead boot-camp classes at regular locations, so people can enjoy the motivational benefits of a group workout. They also offer semi-private and one-on-one training for all ages and fitness level, traveling to meet clients wherever they're most comfortable: at home, the country club, or their favorite gym. No matter which format the training takes, the trainers adhere to the same philosophy. "Life is a marathon, not a sprint," they say. This means that they encourage people to find effective, sustainable activities and to suck energy gel out of packets whenever possible.
