Brazilian jiu-jitsu in Hamar since 2014

Kimura Hamar was founded in August 2014 to be a gathering place for everyone interested in BJJ and grappling in the Hamar region.

The story

We are a club for everyone

Kimura Hamar was founded in 2014 by a group of enthusiasts with a passion for Brazilian jiu-jitsu. Since then, the club has grown into a cornerstone of the region’s martial arts community, offering classes for children, teenagers, and adults.

We place great emphasis on creating a positive, inclusive, and informal training environment. Even though we compete against each other on the mat, we also work together to help everyone around us improve. The sense of community within the club is important to us, and everyone should have the opportunity to develop, regardless of level, experience, or ambition. At Kimura Hamar, everyone is part of the team.

Today we are at Torggata 83, in the middle of Hamar town centre. The hall is large, fully matted and has refurbished changing rooms with showers, and there is easily available parking close by.

The instructors

Three black belts in a town of 32,000

Getting one black belt to settle in a town the size of Hamar is unusual. Having three is almost unreasonable.

Head coach

Known in the Norwegian BJJ community as “The Arminator” for armbars that seem to appear from angles you didn’t know existed. The style is creative, unorthodox, and full of subtle traps, while the person behind it all is about as laid-back as it gets.

Snorre Martinsøn

Black belt

Head instructor for the kids classes and gi-basic

A dynamic style, fast submissions, and guard passing that’s hard to stop. Snorre combines a high pace with clear technique and a teaching style that’s easy to follow.

Snorre is the one most of the kids meet first, and he is the reason the Ninjas class works just as well for the quiet child as for the one who cannot sit still.

Black belt

Head instructor for no-gi

Sigurd is known for his tight half guard, strong underhooks and tricky leglocks. He has travelled the world and trained with many of the biggest names in the sport, picking up plenty of useful details and clever tricks along the way.

Fun fact: Sigurd actually has a technique named after him, “The Sigbar.”

The three black belts set the syllabus, but they are not alone on the mat. Several of the experienced members take classes through the week.

How things are here

Our values

Safety

We should be able to train hard without compromising safety. We look after our training partners, respect each other’s boundaries, and always stop when someone says so or taps out.

Inclusivity

Everyone greets everyone. A club is about more than what happens on the mat. At Kimura Hamar, everyone should feel welcome, regardless of age, background, experience, or ambition. That is why we place great emphasis on respect, a sense of achievement, and community, and on making sure everyone feels like part of the team.

Quality

When you train with us, you should be able to trust that your belt means something. We do not promote you until you are ready, and you should know that your level meets a standard you can be confident in. That means you can visit other academies, both in Norway and around the world, with confidence, knowing that the belt you wear has been earned.

Cooperation

We make each other better. A good training partner challenges you, shares knowledge, and helps others improve. Everyone contributes to the learning on the mat, and we share the responsibility for maintaining the positive environment at our club and making sure everyone gets something out of their training.

The atmosphere

People stay here a long time

Many of the people you meet on the mat have trained with us for years, and our members range in age from six to well over fifty. Some started here as complete beginners, while others joined later, but what many of them have in common is that they have found a community they want to stay part of.

At Kimura Hamar, you are not just someone who shows up for training. You get to know people, find training partners you trust, and become part of a community where people follow and support each other’s progress over time. For many, their training partners gradually become familiar faces, friends, and an important part of everyday life.
