Kate Beckinsale Just Learned That Challenging Your Trainer Is Never a Good Idea

Kate Beckinsale shared a video of herself working out at celeb trainer Gunnar Peterson's ultraexclusive Beverly Hills gym. You may recognize this gym from a recent late-night session between J Lo and Dwayne "The Rock" Johnson or as Khloé Kardashian's go-to spot.

During her session, Kate was brave enough to ask Gunnar, "Is that it?" Bold move, Kate. As anyone who has worked with a trainer knows, these words are pretty much an invitation for not being able to walk the next day. Not skipping a beat, Gunnar immediately increased the incline and resistance on her Versaclimber. For anyone unfamiliar with this torture device piece of cardio equipment, a Versaclimber is like climbing a mountain that never ends.
