Kasia Ostapkiewicz

Hi Everyone!

My name is Kasia. I am a Level-2 Gym Instructor and Level-3 Personal Trainer here at PureGym.  Health and fitness was always part of my life ever since I was a teenager. I Played semi-professional volleyball since my teenage days.

In my personal life, I am a mother of two beautiful boys. I know how hard can it be to lose weight and build muscle as a woman especially after giving birth as I also struggled with that. I am here to share my personal and professional experience with you guys.

So as your trainer let me help you to boost your confidence, regain your fitness and get your body into the best shape ever.

If you need help with your fitness I am just one call away. Don’t hesitate to contact me for a free consultation regarding your goals.

Remember Do your Best to Be your Best.
