French photographer Sacha Goldberger assembled an indoor studio at the Bois de Bologne in Paris, a park two-and-a-half times the size of Central Park, where he stopped joggers mid-workout and asked them do a sprint and then pose for a portrait immediately afterwards. The result? We look wretched when we work out, a fact anyone whose eyes have ever wandered in the gym can attest to. But that wasn’t the only point Goldberger wanted to make. After immortalizing his subjects’ blotchy, red-faced, sweat-soaked visages on film, he asked them to come to his studio the following week, where, using the same lighting, the same pose and similarly-colored clothing he took another portrait.
