An Experienced Team Who Knows Their Craft

Selene Karakaş

Founder, Dietitian and Trainer

10+ Years of Experience

I am the founder and dietitian of Gymnasium13. For me sport is not just a profession, it is a way of life. Since 2017 I have been developing myself in sport and nutrition. Sports nutrition and a performance-focused lifestyle are my greatest areas of interest. My aim is to combine a scientific approach with hands-on experience, helping people achieve stronger, healthier and more sustainable results.

Okan Karataş

Sports Director / Head Trainer

13+ Years of Experience

Sport is not a hobby for me, it is a discipline at the center of my life. I work actively both as a trainer and in club management. I do not see training as just a process of losing weight or building muscle, for me it is a journey that builds discipline, character and self-confidence. When I work with members, I start by analyzing, clarify their needs, and build a program that is entirely personal to them.

Can Saberi

Strength and Conditioning Coach

8+ Years of Experience

My journey with sport began at age six, and it continues actively today as an athlete, coach and instructor. After graduating from Bartın University's Faculty of Physical Education and Sports, I developed myself further through national and international training in strength and conditioning, biomechanics and functional movement. I evaluate movement not just through muscles and joints, but through the relationship between the body's capacity and the nervous system. At the center of my approach is not teaching a single correct movement, but guiding each individual toward safe, sustainable solutions suited to their own needs.
