I found a new studio I will definitively go back to, hopefully often. Mercury Fitness on Laguna Street @ Union, it's listed in my Pilates Studio finder.
I loved this class, I am big fan of the chair, and I felt the class was very classic, with some variations.
The teacher and owner Lara, is super nice and seems very knowledgeable, she
certainly gives a kick ass chair class! I haven't done chair in quite a while, no excuses either since I have 2 Balanced Body chairs in my basement . Well I can't find the handles, so that's why....
Anyway I will try some other classes too, they all have fun names, like: Director Chair, All You Can Eat Mat, Reform School Reformer, Jumpus Maximus, etc. Highly recommended.
