Absolutely. We start with foundations. Every program is customised to your current level and we progress at a pace that's safe and sustainable.

Energy and strength improvements in 2-3 weeks. Visible body composition changes within 6-8 weeks. Our 3-month programs deliver meaningful transformation.

Partner gyms across Brussels. I'll recommend the most convenient location. Online coaching also available for those outside Brussels.

Do you offer nutrition plans?

Yes — standalone or combined with training. Plus curated supplements through the e-shop that I personally use and recommend.
