When you decide to train at Fontaine Fitness, you won't have to sign any contracts or pay through the nose in monthly membership fees. That's because the founder, Todd Fontaine, doesn't want to waste your time—or your money—if you aren't absolutely serious about getting fit. But if you are, the certified trainer makes sure each private 1-on-1 session counts, creating a personalized experience that even extends to the music (he encourages his trainees to bring in their own tunes). And to fortify individual workouts, he offers a variety of group classes that can rope in techniques ranging from yoga to hardcore strength training.
