Ella Loudon in Bathing Suit is "Amazing"

British actress and Daniel Craig's daughter Ella Loudon is channeling her inner Bond Girl on a trip to the luxurious beach resort of GoldenEye, Jamaica. Loudon, 31, shared pictures of her vacation, including one snap of her posing on rocks in an Ursula Andress-inspired white bikini. "Amazing," one admirer commented. How does she stay so fit? Read on to see 5 ways Loudon stays in shape and the photos that prove they work.

Loudon loves to hike, and frequently shares her adventures on social media. "Like all forms of exercise, hiking is one of the best ways to lose weight and is a method of stabilizing cholesterol levels," says the American Hiking Society. "On average, you burn 100 calories for every mile you walk."

Loudon enjoys outdoor sports such as rowing, but rowing on an exercise machine is also a great choice. "Rowing has both an aerobic aspect to it and also a strength aspect," says exercise physiologist Chris Dempers. "You can adjust the tension of the machine for a heavier pull and you're still driving through your legs."

Loudon is a big fan of running and volleyball. "[Running is] a great cardiovascular exercise, because it takes a lot of work for you to move through space with that quick repetitive kind of motion," says Dominic King, D.O. "There's a lot of work done by your quads, by your gluteal muscles and by your core to keep you upright. Running is a kind of coordinated falling, so it's actually a pretty complex mechanism for the body."

Loudon has battled with depression, and says she almost gave up acting because of it. "I don't think it ever disappears," she says. "Partially, the reason was because I think you can only be a good actor if you really know who you are and can completely stay true to yourself, and if my head was feeling the way it was, how could I be a quality actor? So, I didn't want to."

Loudon has dyslexia, and is open about how it impacts her work. "It's amazing how the brain can naturally compartmentalize, but you're also talking to someone who really struggles with learning lines," she says. "There are some people who can just get it. It's not an excuse, but it's something I struggle with."
