Christina has a trick when it comes to eating – she doesn't overdo it. "When your stomach feels full, do not eat past that," she told People. 

Christina is pretty old school when it comes to her diet. "I try to only have a certain amount of calories per day but eat right so I can keep my energy up," she told People. She starts her day with Bustelo espresso and eats an egg white breakfast burrito with spinach, tomatoes, and turkey bacon for breakfast. A few hours later she snacks on a handful of almonds. For lunch she eats a chicken salad with cranberries, tomatoes, and a light champagne dressing. And dinner? Two pieces each of yellowtail, jalapeño salmon and albacore sushi. Her grand calorie total for the day? Just 1,190. She also tries to maintain a low-dairy diet "to avoid cellulite," she tells People. 

"I try to drink as close to a gallon of water a day," she revealed to People. "Hydration is how I keep my skin clear and my body energized throughout the day." According to the U.S. National Academies of Sciences, Engineering, and Medicine men should drink about 15.5 cups (3.7 liters) of fluids a day and women about 11.5 cups (2.7 liters) of fluids.

Christina spends a lot of time working out "Sometimes I get completely focused and I'll go in and work out— sometimes even twice a day— at least three times a week because I'm so excited and really into it. There's other times when my schedule gets really crazy and I have to figure out when to fit it in. And then sometimes I'm just lazy— and it's okay to be lazy. That's balance for me," she told Essence. "I also like to do a combination of cardio and strength training. I've never really been crazy about bootcamps and CrossFit; those are too rough for me."

Christina also enjoys getting her sweat on in fresh air. "I love outdoor workouts. In LA I'll hike up the Canyons at a steady pace; something that gets my heart rate going. 

What makes Christina feel confident? "Working out," she told Essence. "For me, if I'm not in the right shape, I'm tired. I don't have the energy to do the things I like to do, which gets a little bit depressing. Working out is great therapy too. When I workout I pray. In that moment, I am thankful because of my health and how my blood is flowing because all of that stuff is going to keep me around longer."
