Anastasia Ashley is hanging 10 – in her swimsuit. In one of her latest social media posts, the professional surfer-slash-model shows off her incredible body in a bathing suit, in addition to her mad surfing skills. "Afternoon surf," she captioned the Instagram Reel. How does the athlete and poser maintain her famously fit physique? Here are some of her top health habits compiled by Celebwell. 

"I'm in the gym every day I'm not at the beach, doing a mix of cardio and strength-training, such as squats on the Bosu ball, leg lifts and lunges. I love spin classes as well — listening to blaring music and getting super-sweaty," Anastasia tells Men's Fitness. Physical activity is anything that gets your body moving. Each week adults need 150 minutes of moderate-intensity physical activity and 2 days of muscle-strengthening activity, according to the current Physical Activity Guidelines for Americans.

Anastasia eats clean. "Stay away from processed foods. If it didn't come from the earth, it's not meant to be in your body," she says about her top diet rule. "According to the Department of Agriculture, processed food are any raw agricultural commodities that have been washed, cleaned, milled, cut, chopped, heated, pasteurized, blanched, cooked, canned, frozen, dried, dehydrated, mixed or packaged — anything done to them that alters their natural state. This may include adding preservatives, flavors, nutrients and other food additives, or substances approved for use in food products, such as salt, sugars and fats," says the Mayo Clinic.

Obviously, surfing helps Anastasia stay in shape. "Surfing is a full-body workout. When you're riding the board and balancing, you use your legs for balance and stability. And because you're always squatting, which is an uncomfortable and abnormal body position, it challenges your butt and legs," she tells Cosmopolitan.

Anastasia walks on an incline. "While cardio alone won't keep you toned, I walk on a treadmill at a high incline, climb on the StairMaster, and do lots of quick intervals," she told Cosmopolitan. "With the incline walking, I'll do 12 to 15 incline at a 3 to 4 mile-per-hour pace. Even if you jog or run for five minutes on a super high incline, it's still pretty hard!"

Anastasia rides bikes. "I also love doing spinning. I'm a Flywheel fan. It's the best workout overall, and it gets you motivated and competitive," she adds. The Cleveland Clinic explains that biking, a low-impact aerobic exercise, is great for building muscle, improving strength and flexibility, and improving balance. It can also boost mental health and help other health conditions, including arthritis.
