Berry de Mey (1962) is the most successful bodybuilder that ever came from the Netherlands. After he got acquainted with weight training through practicing martial arts, he soon started to focus on bodybuilding. It only took him weeks to realize he wanted to become world champion. He was not just pushed by a desire to become very big and muscular, but also by his passion for aesthetics. He aspired, especially looking at it from a modern perspective, to create a body that was symmetrical as well as big and muscular.

De Mey was enormously successful therein. He became European champion in 1982, and world champion in 1985 at the IFBB World Games. After that victory, he participated in Mr. Olympia four times, the most important bodybuilding contest ever. International reporters started calling De Mey 'The Flexing Dutchman', a title he never lost. In 1988 De Mey won bronze at Olympia.

After he had appeared on dozens of covers of fitness and bodybuilding magazines, and starred in numerous other photo essays, De Mey decided to end his career in professional bodybuilding in 1994. He started to focus on photography with the same passion he had before directed at his sport. And it took only a while before De Mey could truthfully say that his second career was successful as well.

Throughout the years, De Mey continued his weight training and kept up his knowledge of nutrition and sports supplements. He also continued his diet, which made him one of the world's best bodybuilders. And the world changed. More and more people got interested in weight lifting and aimed for a physique like De Mey had like no other in the eighties. An increasing number of people struggled with their weight and were looking for solutions that De Mey had already found decades ago. It was inevitable that in 2010 Berry de Mey Nutrition was born.

'Always realize that, no matter what you do, it is basically about love' De Mey tells everyone he coaches, 'because only then you can reach your true goal.'

Willem Koert (1965) is a sociologist, researcher and science writer. In the nineties he did a research on the bodybuilding culture, and found out that his fascination for the subject was a problem. It was too big. Researchers usually disconnect from a subject as soon as they think they understand it. This was no option for Koert.

To understand why bodybuilders want to improve their physique might be interesting, but the how-questions that arise when you answer the why-questions where even more interesting to Koert. How do you develop muscular strength? How can you make muscles grow faster? How can you burn fat without affecting the muscular tissue?
Koert knew that if he wanted answers to those questions, he needed more in-depth knowledge than researchers can get. He had to bury himself not once, but hundreds of times in the available information. A researcher cannot afford to do this, but a science writer can. So that became Koert's new profession.

Koert started writing about nutrition and health, and specialized in weight training, sports nutrition and sports supplements, and still does. Every day he plunges into new and forgotten studies, and blogs about this on www.ergogenics.org and www.ergo-log.com for an ever-growing audience of interested athletes, coaches, researchers and companies. Besides, his articles are published in Dutch professional journals such as 'Krachttraining en Supplement' (Weight Lifting and Supplements) but also in popular press such as 'Men's Health' and 'Sport & Fitness'.

"To understand the world is nice and well", a German philosopher with voluptuous hair once said, "but what it is really all about is to change the world." And that is why Koert works with De Mey. He has been changing the world his whole life.
