I didn't find the classes challenging at all. I left barely feeling like I even moved my body. This is a great studio to bring mom or grandma to, but not good if you are looking for an intense workout. I understand that not every class can be intense, and that there is a place for lighter workouts. My reason for giving one star isn't that the class was too "easy" for me. It is that the instructor I saw was very rude and almost mean. It was my first class at the studio (but not my first pilates class). When I walked in, she asked me if I had done pilates before, and I said yes. I told her the name of the studio I'd been to before. She responded with "what they do isn't REAL pilates." I was a little insulted because one of my good friends teaches at the other studio. When I tried to modify some of the things she was cueing in class to work better for issues I have with my body, she actually came up to me and told me I couldn't modify. What? In what world can't I go to a pilates class and modify as needed?
Anyways, I had a very poor experience and will not be back.
