Came here to workout with my girlfriend a few days ago. As I am not the biggest fan of working out, I was astonished at not only how interested I was in their workout, but how much I enjoyed it.
Half of the struggle for me when working out is staying focused, motivated, and interested. Orange Theory does 90% of that for you by structuring the workout session, providing a coach, and displaying your heart rate, what level, and how many calories you have burned on two giant flat screens for all to see. There is no better motivator than seeing immediate results, which this place delivers.
The other nice fact was the diversity of the group: you had people from all different health levels working out, so you never felt out of place (as so often happens at gyms these days).
Unfortunately there is not one close by my house, otherwise I would join in a heartbeat.
