Sarah Robles, weightlifting

This California native is a big fan of Recycle Rex, the “spokes dinosaur” for CalRecycle — better known as the Department of Resources Recycling and Recovery. Robles says of Recycle Rex, “it’s a fun place to learn how to recycle.” Remarkably, Robles has only been weightlifting since 2008. She's looking forward to competing in her first Olympics in London.
