“I enjoyed every minute of the training and living a vital life has become my mission. David has the gift of inspiring people and helping them move forward. Thank you for every insight, David! Vital employees are happy employees who willingly go the extra mile.” Bruno Deslé
“Excellent training day! We walked away with a multitude of small changes that we can implement to improve our vitality in the long term. Thank you, David! And thank you to Proximus Group for giving us access to this type of training!” Sophie Nasaridis
“Great training. Lots of practical tips and easy-to-follow guidance. Now it is up to us to put them into practice and improve our vitality. David is an enthusiastic person and an excellent coach.

“Great initiative from Proximus. A sincere thank you to David Dehairs for the energy he brings and his passion for sharing practical experience, together with tips and tricks that truly make a difference.
This session provided valuable insights and practical takeaways that I am looking forward to integrating into my daily routine, especially in an environment where staying active and focused is becoming increasingly challenging.
A must for anyone willing to invest in themselves and take their daily energy to the next level.” Vincent Denoel


“The results of the BeFit @Distrilog programme were so positive after just 12 weeks that we immediately decided to continue our collaboration with David. Participants improved their cardiovascular fitness by almost 50% on average, with the greatest progress achieved by employees who had previously been little or not physically active.
For us, this was clear proof that a targeted approach, combined with personalised coaching and follow-up, truly works. That is why we have committed ourselves to supporting participants over the longer term, ensuring that these positive changes become sustainably embedded rather than remaining temporary.
In addition, a remarkably strong sense of community emerged. Participants motivated and inspired one another, not only within the group itself but also beyond it. This positive dynamic generated greater engagement, enthusiasm and connection throughout the organisation.
With BeFit, we created a genuine win-win situation: more vital employees, more energy in the workplace and an approach that we are confident in extending to future groups.”
Anneloes Cooreman, Prevention Advisor, Distrilog Group


“Through the Vitality Boost @Serco programme, we saw participants gradually reconnect with their health, energy and physical fitness in a very concrete and measurable way.
The combination of scientific testing, personalised cardio coaching, smart monitoring tools and regular follow-up created genuine engagement and sustainable behavioural change. In addition to improvements in fitness and energy levels, the programme also helped several participants become more aware of potential health risks through preventive screening and coaching.
An important added value was the community aspect of the programme. Participants motivated and inspired one another throughout the entire journey, creating a positive dynamic that strengthened consistency, accountability and engagement.
What truly made the difference, however, was David’s personal approach as a coach. His ability to combine expertise, motivation, empathy and accountability ensured that participants felt supported throughout the entire journey. The methodology is strong, but it is the human approach behind BeVital that creates the real long-term impact.”
Justinien Kubwayo, Belux Operations Director, Serco


"BeVital brought a fresh and inspiring dimension to our team building experience. David succeeded in making the importance of physical activity, breathing and mental resilience tangible in an accessible way. The combination of theory, practice and shared experiences not only created new insights, but also strengthened the sense of connection within the team. An experience that stays with you and inspires towards action."

"A truly inspiring and insightful training that helps unlock both our team's potential and our own. Thank you for facilitating not only this training, but many others as well." - Maria Andrianakou, Marketing Manager FedEx
"David, this was one of the best training programmes I have ever attended. The perfect balance between theory and practice, combined with the opportunity to exchange experiences with colleagues. Thank you!" - Natalia Sanchez Pascal, Marketing Manager BPost
"This is a lifetime achievement in its most essential form. It will have changed anyone who participated for the rest of their lives." - Martje Vanderlinden, Vice President Marketing, FedEx Express Corporation

"As a child, I was never really involved in sports. Later in life, I decided to become more active, but I approached it completely the wrong way: too much, too long, and eventually I trained myself into injuries such as plantar fasciitis. A few years ago, I was diagnosed with Type 2 diabetes.
I wanted to start exercising again, but this time in a responsible and sustainable way. I decided to work with David to learn how to train in a more structured and balanced manner, and we chose cycling as a starting point.
Six months later, the results have been remarkable: I continue to make progress without injuries. For several months now, I have no longer needed insulin, something that even surprised my doctor.
Yes, exercise as medicine! When you look at the causes of Type 2 diabetes, I believe the medical world should collaborate much more closely with sports coaches. I have now also successfully resumed running. Oh, and I have lost 6 kg in six months as well 😊"

“An ideal combination of science, experience and practical tips.” - Jeroen
"I did not really know what to expect from experiencing this in a group setting, but I was pleasantly surprised by the motivation and personal contribution of both David and all the participants." - Jo
"The responsibilities that come with being a young parent have accelerated many things in my life. Anything that can improve our quality of life now has my full attention, first and foremost for my family. How can we increase our chances of living a high-quality life by developing healthy and meaningful habits? How can we better understand and manage our thoughts, emotions and needs? And how can we grow towards emotional maturity? I feel that most of these themes were addressed during the workshop." - Kenneth
"It provides a holistic perspective on what vitality really means and offers participants a valuable first experience." - Wim
"David is also willing to show vulnerability himself, reassures participants and gives them the opportunity to explore topics, emotions and personal experiences in greater depth." - Chris

"Every Sunday, our cycling club goes out for an 80 km ride. Since I started training according to the SportMed concept with David about eight years ago, I have never been the last rider on a climb again. I have been riding comfortably up the hills of the Flemish Ardennes for years now, and I am no longer intimidated by the French Alps.
The points system keeps me motivated to continue pushing myself. My lifestyle has improved significantly, and I intend to maintain this enjoyment of cycling for the rest of my life."

"In 2018, I could not even run 5 km, let alone think about doing a triathlon. Yet I signed up for a Short Distance Triathlon together with some friends. I had no sporting background, no bike and was carrying 15 kg of excess weight, but I had plenty of motivation. Training was difficult until I found David.
Thanks to his personalised approach, based on heart rate zones and achievable goals, I started exercising in a sustainable way. No crash plan, no performance pressure, just taking it slowly, training at the right heart rate and staying consistent.
Today?
I support BeVital because I believe in the method. And because I know how difficult it is for a non-athlete to know where to start.
I hope many more people will discover a sustainable way to become physically active through this approach"

"I was already used to running, but thanks to David I learned how to train using heart rate zones. Since then, I have comfortably completed my first marathon (and by now, even three marathons under David’s guidance).
It is hard to believe, but despite getting older 😊, I continue to become faster and faster thanks to David’s training plans."
