Get strong and healthy

CrossFit training three times a week will make you stronger and fitter than you ever imagined you could be! And we will adjust the workouts to your fitness level so you can join all of our classes.

Get more energy and sleep better!

You will start training regularly and will keep track of what you are eating and learning what works for you. If you do this diligently your energy levels will go up and you will sleep like a baby. Trust us!

Get motivation from the group

You have to do the work but you will get help from the group. The best thing is that this is a group process. You will get motivation, feedback and coaching during the full Challenge and also after it is over. 

Lower your body fat

The holy grail of a healthy body and a smaller risk of many lifestyle diseases is a healthy level of body fat. We will track your visceral level and body fat and you will see it going down during the Challenge.

His mission in life is now to help as many people as possible get fitter than they ever thought possible.

You will receive 1-on-1 coaching so you will exactly know how to eat to lose fat. No hunger and with delicious food! We will give you lists with products that are good to eat and what not so good to eat. You will also receive delicious recipes for inspiration. If you don't like certain foods or maybe you don't want to eat meat? No problem! We make a plan based on your personal preferences.

Coaching

We are there for you! A team of trainers and the nutrition coach will guide you along the way.
