Get in shape through a proven combination of coaching, training, nutrition and supplements.



DeMey88 Team
In addition to our “in-house” expertise we also have medical specialists and researchers keeping us up to date with the latest scientific insights. To ensure their objectivity, these loyal advisors have no further involvement in DEMEY88. Our aim is to bring you the best of both worlds; the tried and tested, along with the very latest knowledge!
Doctoral researcher Cas Fuchs deserves a special mention here for his research on human muscle physiology at Maastricht University. DEMEY88 coaching has benefitted from his scientific input and advice.
We would further like to mention Berry’s daughter Noelle de Mey and Ronan Krabben who are both specialized in various coaching techniques and, last but not least, team members Zac Aynsley and Leroy Gilbert, who under the guidance of Berry and the DEMEY88 METHOD booked success in their very first competitions. See more team members below.

8 Team Work

Team Work. In order to ensure quality and continuity, the GOLD membership customer usually communicates with one of the DEMEY88 TEAM WORK coaches. One of the big advantages is that this team is in direct contact with Berry de Mey. Although the supervision by a TEAM WORK coach fits in perfectly with the DEMEY88 METHOD, an assigned coach will, if he or she deems it necessary, consult Berry. If more input is needed, then Berry may contact you personally.  At DEMEY88 we believe that progression stands or falls with the fine-tuning of the many pillars of our method. And fine tuning is something we are good at!!
