Mackenzie, who gave birth to her daughter Moa in 2019, maintains that her body hasn’t been the same since. “My pregnancy kind of restarted my whole body,” she told the New York Post. “I had a really high fat percentage before I got pregnant. And then breastfeeding and Moa getting [bigger] inside of me, she took a lot of my body fat. I lost a lot of muscle during my pregnancy, but I was almost able to start from zero again. … But then, just staying focused and seeing how I didn’t want to get back to where I was before. I’m way more focused. I want to win my fights. I want to do good. I want to have good performances. And having someone depend on you, my daughter, it’s not just me. … I’m getting muscle, I’m working my strength training, and I’m keeping my body fat low. I’m in a way better place now, thankfully.”

2. She Surfs

Mackenzie is an avid surfer. She regularly shares photos and videos of herself surfing. She revealed to the New York Post that her ideal day would be to “Wake up. Go surf then after get a tan. Just relax on the beach tanning. I like to just lay in the sun,” she said. Then, she would eat sushi, go home, and take a nap. “And all this with my family; Moa and my husband together. Wake up. Go for a walk with the dogs. Go watch the sunset. Maybe go to a Brazilian barbecue at night with the family, have some steak.”

3. She Does Functional Training

“I dedicated myself 100 percent, but my training was different than before,” Mackenzie told Women’s Health about how she changed her approach to fitness after becoming a mom. “I did more functional training, focusing on movements with dumbbells and cables, to improve my speed and reaction time.”

4. She Adheres to a Strict Diet
