A great studio, with incredible instructors!!
They work with you and provide lots of great encouragement. They talk you through the postures and help individuals in the class improve. Very supportive teaching style, with positive feedback rather than criticism. I have been practicing there for five years, and both the studio and Bickram yoga are incredible.
I have practiced in other studios in different cities, and the Sweatbox is the best. If you want to practice or try Bickram yoga in Seattle, the Sweatbox is the place!
