I love Pure Barre! It is one of the best workouts I've ever had and it never really gets easier so its difficult to get in a rut. You see results within a few classes and just 10 classes later you start to see a new body.
The classes can be full at times and it definitely requires you to plan ahead but at the end I'm really happy I did it. The only thing that keeps me from going all the time is that the $175 a month can get pretty pricey after awhile and have to take a break.
I highly recommend it and Lift, Tone and Burn on!
