The focus is usually strictly one-on-one training at small gym, but that's not the case at this Andersonville facility. Yes, you can opt for the personal-training package (one session per week, starting at $300 a month), but the gym also offers a regular membership ($60 a month) that includes use of the cardio equipment and classes such as yoga, core training and body sculpting. You can also opt for the best of both packages with the strength-training program ($25 per session) where up to three clients work with one trainer in 30-minute sessions.
