Mont'Durance Strength Training Romy Kasper.jpg

I always did strength training in the past, but with Marjolein it was my first experience with maximal isometric strength training. I liked it and it’s a great advantage that you can do it easily everywhere without much effort, but with great results.

Due to the personal approach of Axel and Marjolein, you feel, especially during the difficult moments, that you are never alone. This ensures that you can work towards your goal in optimal, but realistic conditions, both mentally and physically. Thank you Marjolein & Axel!

She believes that with persistence, motivation and the right team, you can make every dream come true. Periodization, continuous adjustment in a didactically positive & motivating way and the monitoring of mental energy, are the basic principles in her training guidance.
