Karolina counts calories but doesn't avoid anything in particular. "For almost my entire career I had a gluten-free diet, no lactose, I practically did not eat cheese at all … But now I am at such a stage in my life that I think that you need to have a balance and today I eat everything. I went through draconian diets – I will not do it again, I learned from my mistakes. Right now I only look at my caloric balance and this is how I eat it all," she revealed in an interview.

Karolina tries to move daily. "Regeneration is also very important. When I feel like laziness, I feel like laziness and I don't feel guilty about it. However, as a rule, I am practically every day at the gym. At least I do cardio because it is not known if I will have a lot of exercise during the day or not. For example, when I have a shooting schedule all day, I think that my cardio is a shooting schedule, because there is a lot going on there and I change clothes a lot," she said. 

Karolia does aerial yoga. "For the first time in my life I had the pleasure of trying aerial yoga. A beautiful activity that looks light and enjoyable, but is actually a solid and not easy effort. Nice experience ☺️ Have you tried it yet?" she captioned an Instagram post.

Karolina also does a lot of strength training. She recently shared a post revealing that she was back to her gym routine after the holidays. "Strength training includes many other benefits, such as increased muscle tone, and who doesn't want to feel good in a bathing suit? But there are so many other benefits to strength training, including increased endurance and bone density, which is especially important to fight diseases like osteoporosis," says the Cleveland Clinic.

"I am the morning bird," Karolina revealed in an interview. "Every day I get up at 6.00 or 6.30 am. At 10 p.m., forget about going anywhere, because I'm a corpse and I'm just sitting in slippers with tea and just waiting for me to fall asleep." What are the health benefits of sleep? According to the Sleep Foundation, getting enough z's is a mood booster, promotes heart health, regulates blood sugar, improves mental function, restores your immune system, helps relieve stress, and aids in weight loss.
