There is a new trend out there called hot nude yoga (in Swedish naken yoga)! It was first introduced in New York to get more gay men to do yoga (there is quite a large gay community in Chelsea, New York). They say this kind of yoga is a quicker way to connect with the true you . There are no clothes in the way. The trainer can see every move you make (is that supposed to be a good thing?) and therefore assist you in a better way.
