Who Are We?

Hello, I’m Stefan, a fitness veteran with over 20 years of experience, and this is my wife, Marie—my partner in life, business, and adventure.

My journey began as a young boy struggling with being overweight. Determined to change my life, I transformed my body, earned my fitness certifications, and set out to help others do the same.

Marie and I moved to Bangkok, Thailand, where—together with a physiotherapist—we built two thriving fitness studios: Maxfit Bangkok and Maxfit Performance. We offered everything from physiotherapy and bootcamps to high-level personal training, helping hundreds of people achieve their goals.

After nearly a decade of success, in 2017, Marie and I made the bold decision to explore the world by motorcycle—an adventure we chronicled on our blog, Fitness Riderz. With luck and determination, we passed our studios on to passionate new owners who continue to inspire and train others.

Our global motorcycle journey took us across Europe, through Argentina, and up through South and Central America, eventually landing in New York. There, we partnered with an American team to launch a thriving F45 Fitness franchise—quickly recognized as the fastest-growing F45 location on the East Coast.

Then, the Covid-19 pandemic hit, changing everything. We returned to the Netherlands, where I helped build and grow two EMS studios for Nexxt Gym.

On May 30, 2023, Marie and I began our next chapter. Together with a cardiologist, physiotherapist, and dietitian, we co-founded the Leefstijlcentrum Haaglanden, a lifestyle center dedicated to helping people live healthier, more balanced lives.
