XXL Nutrition lives up to its name. It is the largest in Europe in sports nutrition and nutritional supplements for (strength) athletes. Quality and innovation are driving forces in XXL Nutrition's success. Everyone in this company is a fitness and bodybuilding enthusiast. The products are as pure as their motivation. They use their products themselves and know exactly what these offer. And to think it all started with five thousand euros that founder René van der Zel borrowed from his parents in 2004. To make the transition to offline and build a strong brand, XXL Nutrition chose Out of Home Advertising from Trayler. "There are now five trucks driving around and we get a lot of great feedback about it every day," says CEO René van der Zel.
