My group Level 1-2 equipment class experience with Sterling could be described exactly like the explanation of Absolute Pilates classes in the letter asking me to write a review.  Sterling's class (as well as Donna's classes), ease my back and neck pain and stiffness and improves my flexibility.  The breathing technique and body alignment are consistently stressed.  I enjoy my sessions and appreciate the results of the workouts.  I love when my muscles scream at me.  That's what I want (once in a while) :)
