About us

Who and what is the COI?

 The Calisthenics Educational Institute (COI), is the first and so far the only, educational institute in Holland, that focuses fully on calisthenics and functional fitness. That makes the COI the go to educational specialist when it comes to calisthenics and functional fitness. Through the COI you can start as a coach in training and it gives you the possibility  to follow a licensed education to become a certified trainer.

Our team consists of the best and most highly trained functional fitness athletes and trainers in the Netherlands. Our expertise lies in the field of Sport management & Entrepreneurship, Communication Sciences, Fitvak, NASM, Sport & Nutrition, Physical therapy and Marketing.

By bundling our knowledge and experiences, the COI has developed various training courses. COI offers several training courses, each aimed at “functional fitness”. That means that during your workout, you’re not stuck to the isolating exercises that are done on machines, instead you have a wide range of body movement with these exercises. This is because there will be trained more with your own bodyweight. This way, movements from your daily life can be simulated, which builds functional strength. Strength you really need in your daily life. The COI responds to this by offering training courses with a focus on functional strength. The advantage of calisthenics is the fact that you can workout anywhere, both in the gym and outside in calisthenics parks. Educations we provide:
