From a young age, David Peterson, founder of Infinity Fitness, has always had a passion for fitness, the human body and exercise programming. As one of the Fairfield High School ice hockey captains he ran the conditioning program for the team. After graduating from Boston University, Peterson begin his career in the fitness industry but grew frustrated with the limitations of working for a nationwide franchise.

Peterson created semi-private training groups and boot camp programs as a way to allow small groups to work together harnessing the energy and excitement of being in a group of like-minded individuals with amazing end results and an exceptional experience.

Quickly the word spread and the business grew. Even though other attractive locations were available, Peterson knew that he wanted to grow his business in Darien.

Infinity Fitness uses cutting edge techniques that have clients simultaneously toning muscles, building strength and burning fat. The end result is a fast and effective way that allows clients to really get in the best shape of their lives. Infinity Fitness also offers clients a nutrition program called the Healthy Body Formula designed to establish a healthy lifestyle that makes eating properly effortless.

Infinity fitness offers one-on-one training sessions, semi-private training sessions and its flagship BootCamp Program. The fun group atmosphere and tough workouts combine for a great heart pounding, fat burning experience.

"We've had people lose close to 20 pounds in two months," Peterson said. "They earn those results though, the workouts in the program are as effective as we could make them but it's not a magic formula they work hard for the results they get."

Every Saturday at 9 a.m., the gym hosts a boot camp to raise monies for local and national charities. 100 percent of the profits generated from that class are to help the less fortunate.
