Our Mission & Story


It is our drive to help people achieve their physical (and sometimes mental) goals. To allow them to realise, maximise and benefit from the full potential of their own body and health. We improve our clients’ quality of life. It is our goal to enable you to be the best version of yourself.



Based on your goals and wishes, we will work together to draw up a tailor-made fitness plan for you. This plan is based on the four essential pillars of fitness:

1) Training
2) Nutrition
3) Motivation/mindset
4) Lifestyle

Everything we do takes place in a one-on-one setting and by appointment only. You will not find a packed gym filled with groups of sweaty people at 3SIXTY5. We operate luxury private gyms that are frequented by like-minded people.


We are called 3SIXTY5 for a reason. Our brand name is actually inspired by feedback from our clients. It acts as both our trade name and a summary of our philosophy.

Guy van der Reijden, our founder and owner, started out as a Strength & Conditioning Trainer working with top athletes. Guy has been an independent entrepreneur since the age of 25.

In 2005, he began coaching other clients in addition to top athletes, which suddenly turned him into a Personal Trainer (a concept which did not yet exist in Europe yet). His business was called CoachGuy. That is what some of his clients called him and it had a nice ring to it: CoachGuy, Be The Best You Can Be. The trade name was born.

There was just one problem: when things got busier and busier a year later and it became high time to hire more people, the name was no longer good enough. Jelle (Guy’s first colleague) could hardly operate under the name of “CoachJelle.” Since his clients had come up with the name CoachGuy, Guy thought it would be a good idea to ask those same clients to think up a new name for the growing business.

Some of our clients told us that it felt like we were always there for them, every day of the year. That is how the name 3SIXTY5 was born. It is both our trade name and a reflection of our core philosophy. When you are training with us, we will always be there for you.

The holidays are a perfect example of this. Since we are called 3SIXTY5, we are open all year round. Even if you decide not to come in for a workout on a holiday, we will still be working for you.

Because our roots lie in the top sports sector, we approach every client as if they too were a top athlete. We do not simply start working out; instead, we closely examine your baseline level, set goals together and then draw up an effective plan. That is why we achieve such good results, even with people who are not physically fit to begin with. And of course we do our best to make the whole process fun and challenging along the way.

Here is a great example: when Dutch athlete Sven Kramer starts his training for a new skating season with the goal of winning an Olympic gold medal, he does not simply start skating without a specific plan in mind. A goal without a plan is just a wish.
