Aitana loves to go on long hikes in beautiful locations. "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."

Aitana is a big animal lover and enjoys horseback riding. "We all know riding horses is good exercise," says Dr. Dennis Sigler, a Texas A&M AgriLife Extension Service horse specialist and professor in the department of animal science at Texas A&M University in College Station. "Riding a horse for 45 minutes at a walk, trot and canter can burn up to 200 calories. If you do something a bit more strenuous such as cutting or reining, that can come out to nearly seven calories per minute for the entire length of the riding period."

Aitana shares many images of herself swimming both in pools and the sea. "There's also a relaxing, meditative side to swimming," says Harvard Health. "It can come with letting your mind drift as, bathed by soothing water, you focus on your breathing and your movements. This stress-busting aspect could contribute to the cardiovascular benefits of swimming."

Aitana loves paddleboarding, which experts say is great for supporting a strong core. "Back pain is a huge issue for a lot of people and not engaging the core well is often one of the major culprits of aches and pains," says Rachel Williamson, a physical therapist at UCHealth Medical Center of the Rockies. "You may not get a six-pack (abs) from paddle boarding but you will strengthen those deep transverse abdominal muscles which act as your body's natural back brace."

Surfing is another of Aitana's hobbies. Hiking is not only a fun and invigorating activity, it's a great workout. "Surfing can definitely be considered a form of interval training which combines short, high intensity bursts of speed with a recovery phase, repeated during exercise training," says CSUSM professor Dr. Sean Newcomer.
