My 2 girlfriends and I have been taking classes with Yani. She is wonderful! Her instructions are precise and her attention to the details of our body positioning is unparalleled. Really, my body has changed shape within a couple of weeks and my core strength has improved greatly. I'm turning 47 in a few days and I've taken many exercise classes and personal training programs. Yani has got to be one of my best instructors. And their pricing is more than reasonable.
