Terry Richardson’s new ad campaign for Equinox came under fire last week for portraying models who, according to some, looked thin and sickly instead of fit and gym-going. Either way, the pictures aren’t gym-related: Instead of photographing hot people in quasi-pornographic workout positions, as he’s done for Equinox before, Richardson portrayed them wearing skimpy, sweat-free cocktail attire while canoodling in a mansion. The ads are apparently meant to portray fun activities — like simultaneously walking three dogs while wearing stilettos and balancing on one foot — that an Equinox membership might enable you to do; the behind-the-scenes video shows just how complicated some of these activities really are. (Just you try holding table-top position on a tile floor in stiletto heels — well, actually, don’t.)
