“I'm no nutrition expert, but I do eat clean and healthy,” Madison told ESPN about her approach to diet. “I always make sure I have a protein, carbs, and lots of greens. Because I'm trying to gain more muscle mass, I try to eat a lot more. I tend not to eat as much while filming, and I had to set reminders on my phone because it's easy for the day to escape me when shooting.”

2. She Does Yoga and Barre

Madison enjoys low-impact exercise classes. “When I turned 18, I got into yoga and discovered barre classes,” she told ESPN. Why is yoga a great workout? “Researchers found that people who practiced yoga for at least 30 minutes once a week for at least four years, gained less weight during middle adulthood,” Harvard Health says. “People who were overweight actually lost weight. Overall, those who practiced yoga had lower body mass indexes (BMIs) compared with those who did not practice yoga. Researchers attributed this to mindfulness. Mindful eating can lead to a more positive relationship with food and eating.”

3. She Weight Trains

Madison also lifts weights. “I'm usually doing a little bit of everything in the gym and have days in which I focus specifically just on my arms, legs, back or chest. A lot of my workouts also come from watching videos on YouTube and Instagram. My favorite accounts to watch are AnnaVictoria and EmLouiseFitness,” she told ESPN. “I also got into weight training, and in doing so, I've watched my body become much stronger.”

4. She Hikes

Madison also enjoys hiking. While filming I Know What You Did Last Summer she went on a scenic hike with one of her costars. “We went chasing waterfalls,” she captioned an Instagram post.

5. She Practices Self-Love

Self-love is “trusting/believing in yourself fully,” Madison told Glitter. “Its so easy to get wrapped up in social media and “who’s who” we start to forget how truly awesome we are. Just think, as a human being, we have the power to make a difference, make someone smile, forgive others, create new things, think beyond our imagination and so much world. We, ourselves, are so powerful and its so easy to lose sight of that. The second we focus on ourselves and make goals and focus on what makes us happy, we will find that the right people and circumstances will be right infant of our eyes.”
