“There's nothing better than being able to target specific areas of concern and to watch your body transform in the process. Art and the G3 staff not only motivate you to accomplish your goals but they educate you in the process. Generation 3 Fitness is such a great place to get fit while having fun.”

- Nicole H.

"The level of attention, detail and compassion that Art and Jenae have for the members is like a big family. That is what you feel like from the very beginning. Everybody is rooting for you and extremely positive. I feel that joining G3 was the best decision I could have made for achieving my goal of a new healthy fit lifestyle."

- P.G.

"Great family atmosphere with trainers that are patient and customer centric. My wife and I enjoy the small group sessions of 3-5 people per trainer because the workouts are personalized to the individual. The trainers give time and space, yet motivate clients to push through workouts when needed."

- Phil D.M.
