Currently, I am a professional boxer, focused on qualifying for the next Olympics. In my PTBoxing sessions, I emphasize not only mastering technique but also enhancing the overall sports experience. My goal is to share my passion for boxing while creating an enjoyable and motivating environment—where hard work is balanced with a good sense of humor.

Sonny van Putten
During my studies, I became the Dutch National Boxing Champion, and it was during this time that I discovered my passion for coaching. I became a coach for many reasons: to share my love for boxing, weight training, and living a healthy, active lifestyle, while helping others achieve their goals in a fun and motivating way. I’ve been dedicated to boxing and weight training for over twelve years, and I hold a bachelor’s degree in Sports Management and Entrepreneurship. Additionally, I’m a licensed Sports Nutritionist and Fitness Trainer.
Jessy Frempong
I studied Sports Marketing and Management at the Hoge Economische School, and spent 5 years fighting at a professional MMA level. My passion for boxing began in the 90s, the day I first watched Rocky Balboa. From that moment on, boxing has been a constant in my life. The ultimate challenge for me now is to pass on the knowledge and experience I gained as a former pro fighter, helping others build physical fitness, self-confidence, and a positive outlook on life. I’m committed to empowering others to reach their full potential—both in and out of the ring.

I’m a certified fitness instructor with 15 years of experience in sports and health. As a former competitive fighter, I truly understand what it feels like to be in the ring.
Today, I find great joy in sharing my knowledge of boxing and strength training with others. Whether you’re a beginner or have more experience, it’s my passion to help you take your skills to the next level. I believe that focusing on the smallest details is what makes all the difference in achieving lasting results.
Eddy Reijner
My influence extends beyond the ring, impacting lives through my appearances on the Dutch television show Obese.
On the show, I've had the privilege of transforming lives, using my expertise and motivational energy to help individuals achieve their weight loss and fitness goals. I am deeply committed to boxing, fitness, and overall health. Whether I’m training clients one-on-one, leading group workouts, or sharing my knowledge, my dedication and energy inspire others to push their limits and reach their potential.
