It's no secret that Christina Ricci had to get super fit for her role in Speed Racer. But I am really impressed with how fit she actually got. Christina was on Last Call with Carson Daly and she demonstrates how she does a one-arm push-up — she sure puts Carson to shame and he doesn't stop complaining. Check it out.
How cool is that? All while in heels! I've tried and failed, but what about you? Can you do a one-arm push-up?
