The story
What is BECOME?
BECOME is a premium personal training and community concept built in Amsterdam Oud Zuid — one of the city's most respected neighbourhoods. Founded by personal trainer Bas de Jong, BECOME was built on a simple conviction: that training done properly changes more than your body. It changes how you think, how you carry yourself and who you spend time with.
We specialise in strength training, performance coaching and community-driven events for ambitious professionals. People who take what they do seriously — and want to bring the same seriousness to how they train.
The philosophy
Three pillars.
One concept.
Physical growth
Precision personal training and strength coaching. Technically excellent, individually programmed, and always progressing. We build real strength — not just the appearance of it.
Social growth
Sport clinics, network events and community sessions that bring ambitious people together through shared physical effort. Real friendships built in real environments.
Mental growth
Training consistently at a high level builds mental clarity, discipline and confidence that extends well beyond the gym. BECOME is an investment in who you are becoming.
The belief
"It's not about
who you are.
It's about
who you become."
Coming soon
The BECOME app.
We're building a digital extension of the BECOME experience — a coaching app that brings your training programme wherever you are. Whether you're in Amsterdam, on a business trip in London or on holiday in Ibiza.
Personalised workout programmes, video coaching, progress tracking, step challenges and your community events agenda — all in one place.
