A Strong Life
Personalised Training · Proactive Medicine · Amsterdam
KRAFT integrates personal training, habits-based nutrition coaching and medical diagnostics into one sustained partnership.
What KRAFT is
Personal training meets proactive medicine.
KRAFT operates at the intersection of clinical medicine and elite performance. Not a gym. Not a wellness trend. A private, scientific evidence-based studio that delivers measurable results through a structured, personalised methodology - built on years of expertise in the field.
We work with a deliberately small number of clients at any one time. This is what allows us to deliver the level of attention, precision, and continuity that KRAFT demands.
If you're considering starting, we recommend reaching out sooner rather than later.
What we offer
Four services to KRAFT a strong life.
The process
Six steps to live stronger, longer.
Begin your assessment
You reach out. We listen. In a focused intake conversation, we map your goals, your history, and your starting point. No templates. No assumptions.
Diagnostics
Before we prescribe anything, we measure. Depending on your programme, this includes movement assessment, body composition, and optional blood and biomarker analysis. Data first.
Your personal programme
We design a fully tailored plan — training, nutrition, recovery, and mindset — built around your physiology, your schedule, and your goals. Nothing generic.
Train with purpose
One-to-one coaching in our private Amsterdam facility. Every session is structured, progressive, and tracked. You show up. We take care of the rest.
Track. Adapt. Progress.
Your results are monitored across 50+ data points. We review regularly, adjust where needed, and keep moving forward. Precision over assumption.
Graduation
The goal was never to keep you with us forever. When you have the knowledge, the habits, and the confidence to own your health independently — you graduate. That's the outcome we work towards from day one.
Testimonials
Measurable results with lasting returns.
I came to KRAFT with a long history of training and a plateau I couldn't break. Within three months of the diagnostic-led programme, I had measurable improvements in every marker we tracked.
The difference is that they started with data. Not assumptions, not generic plans — data. That changed everything about how the programme was designed.
I've worked with personal trainers for fifteen years. KRAFT operates at a completely different level. The medical grounding makes every recommendation feel precise and justified.
Latest thinking
Clinical rigour. Not trends.
Understanding VO₂ Max: Why It's the Best Single Predictor of Longevity
VO₂ max isn't just a performance metric. Decades of research consistently show it as the strongest independent predictor of all-cause mortality — stronger than blood pressure, cholesterol, or BMI.
