BFitFormula is founded by Martje de Roos, a qualified Personal Trainer of Dutch origine who is specialized in Functional Training.



Martje is registered at EREPS, the European Register of Exercise Professionals.


From her childhood Martje was passionated about human behaviour, music, healthy food and sports. After successfully passing her Master of Laws at the VU University (The Netherlands, Amsterdam) Martje started her career as an analyst and advisor in the area of Dutch criminal law. Besides her office job she studied at the HKU conservatory (The Netherlands, Utrecht) and was  active as a musician. For Martje sports combined with a healthy lifestyle was the key to keep her body and mind top fit and to be successful at all levels of her busy life.


Driven by her own success formula Martje decided to move her passion for a healthy, sportive lifestyle into a more professional direction. In 2015 she became a qualified Personal Trainer and started working as fitness trainer in a gym alongside her regular job. For her family, friends and colleagues it became more and more clear: do you have questions about food, sports or fitness exercises? Ask Martje!


The requests for personalised trainings and food tips gave root to the idea of providing training at home for people with busy lifestyles. Surprised and convinced by the good results of ‘back to basics’ trainings within her own busy life, Martje was curious about this new fitness approach and she decided to increase her knowledge and experience as fitness professional to the level of Functional Training Specialist. Since 2017 Martje lives in Portugal where she established BFitFormula.
