If you want a workout that leaves you kind of wet from sweating and working hard, pure barre Is for you. Pure barre is definitely different from other barre classes in that it moves really fast and doesn't focus on stretching and form as much. That being said I just finished a month of classes at another studio and my form might just be that much better now. It is a much more cardio workout than other barre classes I've taken. You will leave with sweat dripping off your face. I've only taken two classes here but each of them I've left pretty disgusting and sweaty.
I like that the options they offer are actually really challenging, and I don't find myself wondering how I can get more out of the exercise.
One thing I don't like is the room that they teach in, it's small and kind of stuffy, with no fans so it gets almost like a hot yoga studio when you have 20 people working their butts off in there. Also I slammed my shins on the platform in the pure empower class..maybe a warning of where to place my feet on it could've prevented that.
Classes are expensive but if you sign up for the mailing lists occasionally they'll offer a free or discounted class, especially when they're training a new teacher. I think the first class you take is free too. I also got a week free for going to an event they had last week that I learned about via the mailing list.
