Former Royal Marine JJ Chalmers is a TV presenter, but he's best known for winning gold at the Invictus Games (and hanging with Prince Harry). While serving in Afghanistan, JJ suffered wounds to his fingers, elbow, and face during a bomb explosion. He told ITV's Lorraine he signed up to do the show because he's "always looking for a challenge" outside his comfort zone.
