Amazing Success Stories


“I have been working with Marcin for 4 months. thanks to the best diet I’ve had so far, my results have gone up significantly. I feel the increase in strength and endurance, in 4 months thanks to Marcin’s diet, I managed to lose 8 cm from the stomach with a simultaneous weight loss of 4 kg and a significant increase in strength. I find the result more than satisfactory. Marcin cares about the details of the diet, arranging it in a very strict way to what we want to achieve.”


“Marcin and I have been working together for a few months now. I’ve had trouble gaining and keeping on weight for a long time. I had worked with a few other nutritionists before Marcin, but none of them helped me as much as Marcin did. From the start, Marcin treated me as a unique person. He is always in touch with me and keeps an eye on my weight and circuits. He takes his time to answer each question carefully. I truly recommend!”


“You are very honest and easy to get along with. I believe you are passionate about results, and it doesn’t take days to hear back from you as it does with some other dietitians. 😉 Very positive experience. ;)”


“I really enjoyed our training. I think it was good balance of being hard training but also enjoyable. I liked that u explain some things we were doing and explaining about the muscles and what we train. The only thing that didn’t work for me so well was the times, because I had to travel and it was during work hours.
But overall it was very positive for me”


“Fantastic atmosphere at training, quick and tasty meals, results better than expectations”


“I really like how professional the training are, how they are explained, and how they help me understand.

In the gym, you can always laugh and tell jokes while doing your own thing.”
