Jenn's Pilates class was recommended to me by my massage therapist, Julia Keller to help improve my core strength in order to ease back pain.  I'll admit, it was a bit tough, but I haven't exercised in a while and Jenn said I did well (I was surprised!).  I actually signed up for a private class with Jenn to really drill down on the areas I need improvement and to fine tune my posture and poses.
