The studio is awesome, and the workouts are intense! Because you're working multiple muscle groups at a time, I feel like you're getting a much more efficient workout during the 50 minutes you're there. I've been to other Pilates studios, but this one gives the best workout because of the technique and the newer machines. Because they offer so many class times, if you're running late at work or need some extra sleep, you can usually sign up for the next one.
Pilates programs aren't as cheap as some other workout programs, but if you find something you love that works for your body, I think it's worth it.
