Cecily devoted most of her young life to competitive swimming and gymnastics, only to discover Unscared and fall in love with Crossfit and olympic weightlifting. She now spends her days studying veterinary medicine, doing snatches and baking protein filled goods. Don’t let her love of puppies and British accent deceive you however, her puns are still unBEARable.


Jeremy Regensburg

Olympic Weightlifting coach

Jeremy is a competitive olympic weightlifter, occasionally participating in powerlifting meets as well. After being obese and incredibly untalented in most sports during his youth, he finally found a passion in strength training at the age of 20. His anti-talent for physical stuff (you should see his handwriting) forced him to read and work a lot to improve himself as an athlete, giving him many tools along the way as a trainer. He has coached kids with selfdefense, the elderly with retaining their vitality, competitive athletes to meets and injured people back to health. After having helped CrossFitters with improving their technique with barbell exercises, he's excited to train UnScared athletes!



Edward Fijan


Edward has a broad range of experience in many different sports such as soccer, track and field and kickboxing. However, he always missed something in these sports. When he ran into CrossFit it combined everything he searched for in a sport. CrossFit challenged him to train every aspect of his fitness. This resulted into a serious addiction to improve and optimise his movements. Because Edward also is a teacher in physical exercise at a high school, he has a lot of experience in teaching and improving movement. His passion is to help people progress and improve their movement regardless of their current fitness level. He also loves to help people in discovering what their body is capable of.  His ambition is to grow as a CrossFit trainer and definitely also as a CrossFit athlete.





Mariska has extensive experience in training/coaching gymnastics skills. The fact that she works with kids as an elementary school teacher surely helps her keep all the athletes in check during class! You can make her extremely with Tony's Chocolonely chocolate and handstands.

Ben comes to Utrecht from the US and is excited to be a part of the UnScared coaching staff. A lover of all sports that use your hands, Ben formerly played American football for his university as well as club level basketball, baseball and track and field (athletics). Upon finding CrossFit there was an instant connection due to the positive, team oriented community vibe of people working to be their best and he's been hooked ever since. He's looking forward to helping forge a community of fitter people while also getting a few workouts in himself. Biggest vice: French cuisine.




Most of the time you will find Fred around the weightlifting platform. During most of his university years he coached rowing and strength training and he is still a seasonal rowing coach. He was introduced to CrossFit and loved the hard-working gritty mentality that is needed to finish a WOD. He stayed however for weightlifting. His wife is fully aware she has to share him with the Snatch and Clean & Jerk. He is excited to help starting and advanced athletes in improving their weightlifting skills! Strengths: Shouting at barbells. Weaknesses: Roast porkbelly & beer.
