Hydration is a key part of Lana's health mission. "I also drink at least half my body weight, in ounces, of water every day," she told E! "Staying hydrated is such a must- and I genuinely feel better when my body is fully hydrated." "Drinking enough water every day is good for overall health. As plain drinking water has zero calories, it can also help with managing body weight and reducing caloric intake when substituted for drinks with calories, like regular soda.  Drinking water can prevent dehydration, a condition that can cause unclear thinking, mood change, the body to overheat, constipation, and kidney stones," says the CDC.

Lana has struggled with body dysmorphia, revealing to Self her secret trick to overcoming her self-confidence issues. "I have to really, really, really tell myself that I am beautiful and my talent is valid. And I might look a little bit different than I did, whatever, a year ago," she revealed. 

Paolo Mascittii kicks Lana's butt in the gym five days a week, guiding her with cardio and high intensity interval training like squats and lunges. It's no joke, but "it's worth it, because now I have a booty," she told Self. They also do exercises with a slam ball. "I hate it, but it's very effective," she said. "If I'm having a bad day or I have a little aggression, slamming that ball down on the ground really helps me. It always makes me feel a lot better when it's finished." 

Lana gives her body a break if it needs one. "If my body is so sore and I need a day off, he's so understanding about that," she said. "My mental health is the priority, and my mental health is always better when I am active. But sometimes when your body hurts, you're like, I can't do anything, I don't want to get up. And so he's very patient. If there's a day that I feel the need to be a little bit more gentle with myself, he's great."

Lana is a fan of jump roping. Not only can she do it anytime, anyplace, but it's a great cardiovascular workout to help keep her heart rate up. Says the Mayo Clinic: "Before you pack away the kids' jump rope with the summer toys, you may want to consider this jump rope workout. This jumping circuit is an efficient way to keep up with your workouts while juggling commitments or traveling this season. (Jump rope not needed if you'd like to just replicate the motion.)df44d9eab23ea271ddde7545ae2c09ec

Start with a 5-10 minute dynamic warm-up. We suggest 10 moves of each: knee hug; toy soldier; squat; alternating front lunge + rotation; seal jacks; cross country ski; high knees; and hand walk. Then, continue with this circuit of 10 moves and repeat two times with a 30 sec rest in between."

Lana's fiancé, Anthony De La Torre, is also her accountability buddy at the gym. "Anthony doesn't particularly love when I cheer him on when he's lifting, because it makes him laugh, and then he drops it," she revealed to Self. "So I'm not allowed to cheer him on, but he could cheer me on." "Working out with your spouse or significant other gives you a support system — and a healthy dose of accountability. In addition to making certain workouts more fun, having a spouse along means you can encourage each other when you hit a wall. If you aren't in a couple, bring a buddy," says the Cleveland Clinic.

"I always do a little bit better in a class setting or in-person, just because I think that I have a competitive nature in workout classes," she told Self. "So I feel like I can really hit it hard." Pilates, boxing, and hot yoga sculpt classes are a few classes she likes. "Starting a fitness program may be one of the best things you can do for your health. After all, physical activity can reduce your risk of chronic disease, improve your balance and coordination, help you lose weight, and even boost your self-esteem," says the Mayo Clinic.

Lana encourages people "to eat what makes you happy," she told Bon Appetit. Her theory? Eat what you want but in moderation. "I've tried to take away noodles in my life, and it just doesn't work—I'm miserable! I always think to myself, 'Well, I could starve myself and go on a diet and be fucking miserable. But what if I die in a plane crash? Or, what if I have the most amazing meal of my life, and then I could still die in a plane crash, but at least I'd have a happy belly!"
