I had a friend who was doing hot yoga and raved about how much she enjoyed it. When a groupon came along for ten sessions I couldn't resist. Yes it is hot. Not AZ hot but like steamy jungles of South America hot! In just a few sessions I could really see and feel that my body was changing. My groupon is used up, but I am still going to Sumits.
What I appreciate is that you determine how hard you are working. The staff encourage you to listen to your body in determining how much or little you do during any one session. The staff also offers gentle corrections on posses so you don't injure yourself.
Men and women attend the classes. Guys don't be intimidated thinking its a chick thing. There are lots of guys who attend.
TIPS:
Drink lots of water day of practice. A lot! You will be sweating like you never have before and it is very easy to get dehydrated.
Don't eat anything for a least of couple of hours prior to the class.
If you are not sure what kind of mat or towel to get, you can rent them at the front desk. They are good quality and very sanitary.
Dress for comfort. Every part of you will be soaked thru with sweat. Think of that when determining what you are wearing. Many of the ladies will wear Yoga Capris and a long sports tank. Wearing a tee-shirt was too distracting to me as it would bunch up and stick.
