Personal Trainer
Jules
Hi, I am Jules, a final-year student in Physical Education & Movement Sciences and a trainee dietitian. With a background as a former soldier and a lifelong passion for sport, I have been around training and movement my whole life.
Since 2020 my focus has been entirely on strength training and a healthy, active lifestyle. In 2022 I started coaching, driven by the ambition to help both beginners and advanced athletes grow through a scientifically grounded approach.
My personal expertise lies with athletes and performance-minded clients who want to build on their goals. I am constantly chasing goals myself: running a marathon, competing in a bodybuilding contest, finishing the Dodentocht, 1,000 pull-ups as fast as possible… I train from one goal to the next. I use that same focus to help you reach yours.
Over the years, work and internships brought me into contact with various gyms and coaching centres, but nowhere did it quite click, until I met Coach Redert through university. During my internship at RT Training & Coaching I was welcomed warmly and immediately felt the combination of professionalism, expertise and a family atmosphere. That was exactly the environment I was looking for.
I believe strength training, sport and movement add enormous value for every individual, regardless of age, background or starting level. For me, functionality, fun and individual guidance come first.
I focus on correct technique, progressive build-up and a coaching style that goes beyond simply performing exercises. I look at the complete picture: training, lifestyle, motivation and lasting progress. My goal is that every client — from competitive athlete to business owner — feels stronger, healthier and more confident in their body.
