About Flex Gym

Flex Gym is founded from the belief that everyone can live a healthy life, but it’s not equally easy for everyone. For example because it’s hard to find the time and energy to exercise. Or because physical and mental limitations are holding you back. Due to all the food hypes, it can be unclear what healthy eating is. And with a stressful job and the need to be online 24/7, relaxing and sleeping can be a challenge. Old habits are hard to break. And feeling less vital can cause insecurities, that make it even harder to break through those old unhealthy patterns. Lifestyle coaching can facilitate your road to a healthier life.

  • Create your own health. Where and whenever you want!©

Flex Gym’s slogan is: Create your own health! Our key point is Positive Health: We are deeply convinced that independence is the key to lasting success. No one benefits from long term dependence on a personal trainer or nutritional coach. Learning how you can live healthy on your own power and develop healthy habits, is far more valuable. We coach you in a way that fits your life as perfectly as possible. To lower the barriers for you to live a healthy life, we will meet you wherever you like and coach you at home or at your workplace. FLEXible and Mobile.
