Nina enjoys exercise, including yoga, HIIT, and boxing. "I just love working out," she told Women's Health. "Doing something different [each day] has been the most fun, and I've seen the most benefit because you shock your system.” She added to Shape that strength training is one of her main methods. "I actually did not do a lot of [strength training] in the past-I only did yoga and ran in terms of training. Strength training with weights and such a regimented schedule has been new to my life, and now that I understand the way it all works, the science behind it, it's changed everything for me.”

2. She Is Active Outdoors

In addition to her regular workouts, Nina stays incredibly active outdoors. Aside from scuba, she hikes, skis and snowboards with beau Shaun White, and rides bikes.

Nina makes sure to eat throughout the day so she doesn’t get too hungry. "I used to eat three full meals and then I would not be able to move after each meal. I would be so full and tired. Now, I eat all the time but portion control is what's important for me-I'm eating more in total but not more at a time,” she told Shape. “Basically, I aim to have the size of my thumb in fat, the size of my palm in protein, and then unlimited veggies. I wish I'd learned this in school."

Nina also keeps herself hydrated with healthy juices. "When I'm sick or not feeling great, I'm all about the juices," she told Well+Good. "It seems like the worse the taste, the better it is for you, so I do ginger, garlic, cayenne pepper, oregano oil—ugh, double ugh— lemon, everything." Sometimes she even adds collagen peptides for a bit of protein.

5. She Pumps Herself Up with Music

"Music is a big part of my training and my life. Before I had a trainer I would go to the gym and go on the treadmill and whenever it was the chorus I would sprint and whenever it was not the chorus I would just jog. If there's a beat I can usually get into a groove and sense what's happening and if something burns I just plow through it because the music is what drives me,” she told Shape.

6. She Exercises in the Morning

"You need to make a decision-do I want to look and feel a certain way and put the work into it? I see the difference so I make the time for it on set. I would wake up an hour earlier. Even though I was exhausted after a 12-hour day and did not want to work out, I did it because I always knew I would feel better after,” she explained to Shape about why she gets her workouts in early in the day. “I do it first thing when I wake up because then I can't make up an excuse for it, like being tired later on in the day. Because usually by 6 p.m. you're just like, I have no energy. I've done all the things I've done! I don't want to do anything else! I just get it done in the morning."
