One of the best things about London is that when the sun comes out, people taken advantage of it while they can. Barbeques are organised hastily, pub gardens fill to overflowing and the parks are littered with sunbathers. Roberto had it all going on. I was scanning around the crowd looking for a subject and there he was by himself doing push-ups and being just generally buff. It turns out he's only been in London for 3 months. He's from Puerto Rico and teaches salsa.
