I have been training with Dion since May '21. First especially outside, at the most beautiful locations in Dordrecht such as the Wantijpark and on the Schuttevaerskade. He taught me the basics and techniques of boxing. It's great that he is so patient and feels good about what suits my level and goals, which means that the training is really tailor-made. Now that we train indoors and he has his own beautiful gym that is fully equipped, we mainly focus on strength and working towards my goal to be fitter for a mud run in which I will participate in October. Dion has made an appropriate program and sets of exercises and keeps track of my progress. I would recommend him to everyone, he is knowledgeable, thinks along with you, radiates peace and motivates you to go to the extreme.
