The big rocks ofcognitive & physical performance 


Optimizing your nutritional status with a sustainable plan of action greatly increases the likelihood of  favorable changes in body composition and performance outcomes. 

Likewise, nutrition has been shown to have a profound impact on cognition and brain health.



Well designed training plan will allow you to force your adaptation(s) of choice (your body's response to training, be it physiologic, physical or performance based)   

Equally, exercise may well be the most reliable and underrated cognitive 'enhancer'. 

Sleep & Stress Management

Crucial to physical recovery, healthy brain and everything in between, sleep is the ultimate performance enabler.
Learning how to manage your state and getting a grip on your runaway thoughts will facilitate all aspects of recovery.

Client Testimonials

A no-nonsense approach with a touch of gentleness, tailor made approach and well- founded advice is his recipe and that is what you will get. Passionate about training, taking care of his clients and extremely knowledgeable about nutrition. Kamil is not only a coach; he is a mentor...

I have met Kamil upon recommendation of a mutual friend whom I have seen growing considerably in terms of strength. I quickly understood that Kamil is not any coach but a coach with in-depth & thorough knowledge of sports science and other related sciences such as nutrition, biochemistry, sports neuroscience and many more. Kamil struck me as an expert, someone who knows his stuff, and is a professional in the field. I was looking forward to receive my protocol and was not disappointed with the ideas that Kamil had put together. In & Out the sessions Kamil has also shown to be a coach with great values and that it is easily possible to be an expert but to remain human and humble, supportive, open, understanding and caring. The company I work for has three core values; Lead, Deliver, Care. I believe Kamil is a good representation of such values as a coach. Together we made a lot of progress on myself, the main one being in the strength gain and stress reduction. In the space of 5 weeks I went from failing a single rep on 80kg (which I never performed before) to managing 1 rep at 90kg. This was not a pure strength gain, I also improved at technical realization and movement execution. Kamil has also took a lot of time for me outside of the sessions to try to understand me better and support me better, not only as a coach but also as human being. We sat in coffees after some workouts when my mind was troubled, when I needed insights or when I needed to celebrate an achievement. One particular moment I remember is when Kamil roleplayed with me, as I want to become a coach myself Kamil played the role of difficult customers to see how I would react. Thanks to him I feel more confident overall in the field of sports but I am also learning a lot of valuable lessons about (my) life. If you are looking for a coach I would definitely recommend Kamil, but if you are looking for more well you will be well served too beyond expectations 🙂 Thanks a lot for all your work so far!


Between April and July 2021, I had the opportunity to have a set of 10 sessions of one-to-one Sharp Mind and Body consultations with Kamil. As a goal-oriented person with a scientific and technical background, I expressed my clear needs, goals and a pre-defined timeframe I expected the optimal high performing results to be reached by. Following my clear input regarding desired results, Kamil proposed a personalized plan, modalities, diet, and physical training schedule, all supported by scientific articles backing those lifestyle changes. During the 1-to-1 weekly consultation sessions, we had the opportunity to exchange and mutually challenge our points of view. Kamil took the time to give scientific-based arguments answering all my concerns as we discussed the latest research findings on the topics of interest. I experienced continuous increase in my physical performance and mind sharpness from the second week of the agreed personalized plan of modalities, one which I followed with a stoic discipline.


I am grateful for Kamil's evidence-based advice, always on point ! Our consults are insightful and help keep me on the right track, while adapting my nutrition plan as we go along.
