Orange Theory provides a really good, hour long workout. It's pretty clearly a money trap - but honestly the workouts are great and for me it was worth it.
You have to sign up for a specific workout in advance, and if you don't show/have to cancel, you get charged $12. While this is motivating for some, it's not exactly flexible. I was happy for a while but if you don't know your schedule in advance, it's almost impossible to get into a class at peak times (4:00,5:00,6:00) so you really need to have a set schedule or be willing to go later on in the evening.
I was happy there and it helped me get in shape for my wedding. My schedule unfortunately has changed so I went in to cancel, and they have this ridiculous "30-day notice policy" which basically means they'll charge you a full month extra no matter what.
Kinda crappy.
Otherwise I had pretty good experiences!
