What people think of KO FIGHTING FITNESS
  • I have been a member of KO FIGHTING FITNESS for some time now. What I like about this gym is the personal approach of the trainers. Where other gyms sometimes have a very large number of members, you really notice the very personal attention that the trainers have for their members. Great!

    Johan Korte - The Hague
  • I have already been a member at many gyms for fitness and kickboxing, but what makes it so much fun here is the versatile range of different group lessons and the outdoor area where you can train in the sun in the summer. Really a super fun and accessible gym for every level!

    Jet Lange - Kijkduin
  • KO isn’t just any gym, I feel like I’m part of a family. The attention to detail is amazing during each lesson. My daughter is so comfortable with both BJJ and MMA. The other children in the school show respect and are always friendly and helpful. I especially enjoy the ladies only classes and my husband thinks Jiu Jitsu is the next level. I would definitely recommend the school to anyone looking to learn a skill that will last a lifetime!

  • Super experienced and good instructors and very nice intensive lessons!
