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. Our goal is to offer advice and coaching to everyone who finds it difficult to eat healthy and exercise regularly. For example because due to all the foodhypes nowadays, it is unclear what healthy eating is. Or because it’s not possible to exercise regularly because of a busy job, family life, being overweight or age- related limitations. We do this in a way that fits your life as perfectly as possible. Therefor we will meet you at your home or workplace. FLEXible and Mobile.


The team has many years of experience in individual and group coaching in nutrition, exercise and lifestyle. We specialize in weight management, sports nutrition, emotional eating disorders and in nutri- gerontology focussing on Healthy Ageing. We are deeply convinced that independence is the key to lasting succes. No one benefits from dependence on a personal trainer or nutritional coach. Learning how you can live healthy on your own power is far more valuable.
