My wife got me to sign up. I've gone to about 8+ sessions (just over a week now). I only see a small difference physically so far but I feel significantly better which is my personal goal. I want to feel fit and perform outdoor activities easier and go for a run without heaving heavily at the end... So far so good. No complaints. I burn anywhere from 850 - 950 calories each session. The rowing and treadmill portions are generally the same and it can be easy to get bored with the treadmill in particular but they both have their place in the overall workout and are beneficial as they keep the heart rate up before/after you do the dynamic exercises in the bench room. There is always a dynamic element to each session as each trainer has their own routine for the workout room which are essentially total-body workouts but tend to have a focus on abs, legs, cardio, etc depending on the trainer. Each trainer has their own selection of music also which keeps the overall experience fresh. The customer service is great and the trainers are very helpful if you have questions. Good experience this far.

Update: They are under new management and make cancellation impossible - my wife has been trying to cancel for a few months now and they keep "forgetting" to call back.
We have gone in several times and the first time they stated they no longer utilize cancellation forms and that a manager would need to perform the cancellation. The manager never seems to be in and never calls us back and we have been charged 3 times now since we originally tried to cancel my wife's membership.
Also now they have delayed even more by emailing a cancellation form to fill out (even though we filled one out in person); and this is after they told us that they supposedly no longer utilize cancellation forms. Until they change such practices, avoid this branch.
