Marta Kostyuk is hitting tennis balls – in her two-piece set. In a new social media post the tennis star shows off her amazing body in her tennis whites, throwing her fans into a frenzy. “It’s just amazing how absolutely fit Marta is!!,” writes one of her followers. “Totally toned muscle 💪.. and very beautiful too.” Another added: “Marta Kostyuk looks very strong.” How does she approach diet, fitness, and self-care? Here is everything you need to know about her lifestyle habits.


1. How She Got Into Tennis

Marta explains how she became a tennis player. “My mom was working a lot when I was small and, I don't remember it, but my mom told me that I wanted to play tennis so much so I could see her. I have two more sisters, one older and one younger. I was in the middle but it was the period when my mom was working so much as a coach. I didn't see mom that much. I wanted to see her a lot, so I was practicing. In the summer I was on the court from 8 in the morning to 8 in the evening, from when I was 4 or 5. At the same time I was doing pairs acrobatics, from 5 to 11. We finished fourth place in the national championships,” she told WTA Tour. “Tennis was the main goal, so I decided to stop acrobatics. I had to be so careful with my weight and it was so much stress. Evey day I was coming from school worrying about my weight. When I was 11, I decided to stop.”

2. Swimming

Marta enjoys swimming. Swimming is a good way to get regular aerobic physical activity, according to the CDC. Just two and a half hours per week of aerobic physical activity, such as swimming, bicycling, or running, can decrease the risk of chronic illnesses. In addition to the many physical benefits, there are multiple studies supporting the mental health benefits of swimming as well.

3. Stand Up Paddleboarding

Marta also enjoys stand up paddleboarding. The American Council on Exercise (ACE) agrees that paddle boarding is great for the core and also a great form of cardio. The water sport can burn an average of 385 calories for a 140 pound male and 436 for a female the same size, per a study conducted by Arizona State University.

4. Strength Training

To get her body ready for the court, Marta spends time in the gym strength training. “Warmed up? Yeah, dead,” she captioned a post. According to the Mayo Clinic, strength and weight training help reduce body fat, preserve and increase lean muscle mass, and burn calories more efficiently. Strength training may also help you:

  • Develop strong bones
  • Manage your weight
  • Enhance your quality of life
  • Manage chronic conditions
  • Sharpen your thinking skills

5. Surfing

Another stay-fit in the water activity of Marta’s? Surfing. According to the Australian government’s Better Health, surfing provides many health benefits including cardiovascular fitness from paddling, shoulder and back strength, which also strengthens from the paddling, and leg and core strength. “Once you’re standing up on the board, strong legs and a strong core will keep you up,” they say.
