A little background -- When I graduated college 5 years ago, I flirted with Bikram yoga for about 3 months; while I loved the workout: the price tag, culture of the studio and lack of variety ultimately didn't work for me.\r
After taking a 4 year break, I decided to try out Sunstone. Not only is the workout equal and/or superior to other forms of ""hot yoga"", it's less expensive, the instructors are all super friendly/helpful, AND (best of all) they offer a variety of classes. \r
In addition to the Fire series (virtually identical to Bikram), the Wood class focuses on core strength (like pilates) and the Earth series is more about general physical fitness (like push-ups).\r
If you hate the gym like I do, give this a try...it could be the best $10 you spend for years.
Pros: Variety, Price, Service, # of Locations
