About
Meet Joris
I've spent the last 10+ years in the gym, training myself, learning the literature, and helping others get stronger, leaner and healthier. Sci-Fit is the platform I built to do that at scale, online.
I'm a graduate of the Henselmans Personal Trainer Course, one of the most rigorous, science-first PT programs in Europe. Everything I program is built on peer-reviewed evidence and tested in practice. No guesswork. No "secret hacks". Just principles that work.
Henselmans PT certified
Evidence-based training & nutrition.
10+ years of experience
Real-world application, not theory only.
Goal-first programming
Strength, hypertrophy, body recomposition.
Sustainable approach
Adherence over perfection. Always.
My philosophy
The best program is the one you actually follow. I design plans that fit your real life: your schedule, your equipment, your recovery, your preferences. Then I tune them every week based on your data and how you feel. Progress isn't linear, but with the right framework it is inevitable.
