WNBF Netherlands is the promotor of the World Natural Bodybuilding Federation in the Netherlands. As such, we organize the international open Grand Dutch Naturals Cup each year. This competition is the national championship of natural bodybuilding. On top of that, the competition is eligible to award WNBF Pro Cards and the international qualifier for Dutch natural bodybuilders.
As a natural bodybuilding organisation, we place great value in a natural, healthy lifestyle and competition. Therefor, we are the most stricktest tested bodybuilding organization in the world.
Apart of the Grand Dutch Naturals Cup, we organize multiple workshops about natural bodybuilding throughout the year. These workshops take place at various gyms. Here we present about how to prepare for competitions, latest scientific insights into natural bodybuilding, how to reach your natural potential and we practise posing.
