Small group training is fun, motiving, and more affordable than individual personal training.  This choice allows for up to three participants in a particular session.

Benefits of Small Group Training:

Motivation - You're more motivated to workout thanks to the psychology of relatedness.
Stress relief - No need to worry about finding a friendly face at the gym.
Fun - Since sessions have other people in them, there may be some partner exercises.
Planned variety - Trainers have written a great training session so you just need to show up.
Personal attention - Small group training is sized to keep a focus on you.
