(T)he new naked yoga class on Sunday mornings at the One Taste Urban Retreat Center on Folsom Street is meant to be transforming, not titillating. That's a concept that American culture, with its taboos on nudity, might find difficult to grasp. The center, which opened 10 months ago, was founded by Nicole Daedone, also a co-founder of 111 Minna Gallery. It offers dance classes and massage, has a small cafe and an art gallery, and hosts various events.

The class is about the challenge of yoga, and about the challenge of accepting -- and even revering -- one's own body.

"It's not a sexual experience", said Rob Kandell, the center's business manager. "It's a heart-opening experience."

First Apple Bottom and probably one of the most famous we will take a look at! It's none other than that sexy Williams Sister in the famous catsuit. Do yu see the way that Serena's apple bottom claps when she is about to return the serve?Gravity is her friend and our friend. Serena has thick muscular legs. Her buns of steel are built perfectly. See how round and shapely it is? It pokes out from her back, then goes into a complete circular curve until it hits her hamstrings. That visitors is an apple bottom in motion!
