About Mariyan

I’m Mariyan, and I am proud to be a part of the BTX team.

Since my early years, I have been immersed in various sports, such as football and boxing. It became clear to me at a young age that my future would revolve around the world of sports.

With over 10 years of experience in the fitness industry, I have developed a strong passion for callisthenics, functional training, powerlifting, and boxing. Intrigued by the human body and the scientific principles that govern its unique processes, I pursued a degree in Biomedical Science.

This educational background laid a solid foundation for pursuing my passion in fitness and comprehending the diverse training protocols necessary for muscle growth. Eager to expand my knowledge, I pursued a Masters in Sports and Exercise Science, allowing me to delve deeper into the subject.

As a personal trainer, I prioritize performing exercises correctly and safely to maximize results while preventing injuries. Having personally experienced my fair share of injuries, I understand the importance of proper technique and movement execution.

Throughout my career, I have had the privilege of working with individuals from diverse backgrounds and various age groups. I am thrilled to extend my expertise and help you achieve your goals. Let’s embark on this journey together.

I’ve been training with Mariyan for over a month now and already 3 kg down + dropping body fat and retaining muscle. I’ve been on various fad diets before so it’s good to see I can eat a healthy balanced diet and still lose weight. Mariyan is very supportive and makes sure all workouts are challenging. Highly recommend! 10/10
