My boyfriend has been raving about Sumits Yoga for the last few months, so I finally decided to go with him and I am HOOKED. I was one of those people who thought yoga was only about stretching, holding poses and not much of a workout, but Sumits Yoga has completely changed my thinking. It is a great workout and as they say in class, you can feel your body being wringed out, like a sponge and all the toxins and nasty stuff spilling out. Most of instructors are attentive, knowledgeable and fun and a plus is that they play good music during certain points in the class. Anytime I'm up in Scottsdale, I always go to their classes; I'm still hoping and waiting for a Sumits Yoga to open in Tucson!
