Derk Bos

Let me intruduce myself. I am not only a fitness expert, but a dedicated and fully certified personal trainer.  

My path led me from being in a high profile job in the corporate world via managing various top-tier fitness clubs to a transformative learning experience at Australia's FIA and America's NASM.  

I know firsthand the challenge of balancing a demanding corporate career with the commitment to physical well-being.  

My more than 20 years in the fitness industry have shown me the ebbs and flows of fitness trends and 'fitfluencers'.  

What I've distilled from these experiences is a simple truth: timeless, foundational principles are at the heart of true fitness. 

This insight resulted in my unique fitness philosophy – 'Simply-Effective'. This approach strips back the complexity, focusing on Optimal Performance Training principles.  

It’s about delivering no-frills, comprehensive training that harmoniously blends flexibility, balance, strength, and endurance.  

This is not just training; it's a progressive journey tailored to your personal goals, leading to Simply-Effective results that truly belong to YOU. 

I'm proud to offer these training services not just to the athletic and active but also to senior+ clients. My commitment is to provide an inclusive, welcoming, and safe environment for everyone to thrive in.
