Boxing is thestartingpoint.
At JOH. Boxing you learn more than throwing punches. You work on technique, conditioning, discipline and confidence. Our classes are accessible for beginners, and challenging enough for experienced boxers.
Everyone trains at their own level. We build a strong, involved community: a boxing gym in Amsterdam for adults who want to grow, on and off the floor.
R.D.U.
Respect. Discipline. Unity.
Respect bepaalt hoe we met elkaar omgaan. Discipline bepaalt hoe we trainen. Unity zorgt ervoor dat niemand het alleen hoeft te doen.
Respect
Respect is the foundation. Respect for yourself, for each other and for the craft.
Discipline
Discipline is the choice to keep showing up, keep learning, keep working — even when it gets heavy.
Unity
Unity is the power of doing this together. We train as individuals, but grow by making each other stronger.

Built fromexperience.Created forcommunity.
JOH. was born from the belief that boxing can take people further than just physical fitness.
Founder and head coach Glenn Mulala has more than ten years of experience in boxing. He fought at competition level, won gold at the Northern-Dutch Championships in 2014 and was ranked in the Dutch heavyweight top five in 2015.
With JOH. Boxing he's building a space where quality and accessibility meet — a place where people learn to box, build discipline and become part of a strong community.
Master thefundamentals.
At JOH. boxing goes beyond technique and conditioning. It's a way to make body and mind stronger, to build discipline and to develop confidence in yourself. From respect for each other we create a space where everyone is pushed to grow — as a boxer and as a person.
