I am a former FS in the French army and law enforcement officer, I have seen a lot of trainers in my career but Mariusz is probably the best one I had an incredible experience with Master Athletix Coaching. I had been struggling with shoulder and elbow pain for a long time, trying various methods to find relief without success. Mariusz managed to heal the pain in just a few sessions, which was nothing short of amazing.

His approach is professional, highly effective, and tailored to individual needs. Beyond rehab, his training programs are on another level—challenging, well-structured, and designed for real progress. Mariusz is truly qualified and knowledgeable, and I can’t recommend his services enough to anyone looking for top-tier rehab training and coaching. Thank you again, Mariusz!
