I've been to a lot of Bikram studios and The SweatBox community is unparalleled.
The owner and instructors have years and years and years of experience and practice and do an excellent job of correcting your form so you can improve and avoid injury. They are also great at helping you adjust and modify for any existing injuries so you can practice during recovery.

They are also just incredibly nice and welcoming as are the people who practice regularly at the Sweatbox.

The studio is well maintained and clean. The heat is consistent (and during the winter like a tropical vacation). Cannot say enough good things about this place!
