I cannot prize Marcin enough!

Marcin has looked after me for about a year just until recently. I cannot prize him enough, he really changed my life! I came to him for an advice regarding losing weight. He listen carefully to my concerns. He worked very closely with me and was approachable at all times. My therapy was a huge success, I lost 18 kg in a few months and I maintain it until now. Marcin is also providing comprehensive care, as he planned my physical activities too on a professional level. Marcin is a very professional specialist, his knowledge is really deep and his approach extremely friendly. I would very strongly recommend him!Marcin Kazmierski

I Highly Recommended: A Thoughtful Approach to Nutrition and Healthhad a very positive experience…

I had a very positive experience working with Marcin Siankowski at Yorkshire Lab. What really stood out to me was his thorough and personalised approach. Before making any recommendations, he first asked me to do a full blood test to check for any mineral deficiencies and to assess my hormone levels. This gave us a clear starting point based on my actual health needs.
Our first consultation focused on understanding my lifestyle and preferences, which made me feel fully involved in the process. From there, Marcin created a tailored plan and we continued with regular meetings to monitor progress and make adjustments as needed. The changes weren’t rushed – it was a gradual process – but I can genuinely say it led to a real transformation in how I feel.
I truly appreciate Marcin’s professionalism and care, and I would confidently recommend him to anyone looking for a knowledgeable and attentive nutrition specialist.

I would like to share my positive…

I would like to share my positive opinion about my personal trainer and nutritionist, who significantly helped me on my journey to better health and well-being. His approach to weight loss was extremely professional and based on understanding my needs and the mistakes I had made in the past.

The trainer created a diet plan for me that was not only easy to prepare but also delicious and satisfying. This made it so I didn't have to spend hours in the kitchen, which certainly made it easier for me to incorporate healthy habits into my daily life.

Additionally, he prepared an excellent training program that I could do both at the gym and at home. It was tailored to my abilities, allowing me to gradually increase the intensity and achieve my goals.

I also greatly appreciate his support – I could always count on him whenever I had questions or doubts. He responded quickly and thoroughly, which gave me a sense of reassurance that I wasn't alone on this journey.

I wholeheartedly recommend this trainer to anyone looking to improve their health and well-being. His knowledge, professionalism, and individual approach are truly invaluable!

Highly recommend dietitian

Been working with Marcin for a good few months and I’ve noticed huge improvements. I can tell that Marcin has massive background knowledge about nutrition and it shows whenever we have a check in. My diet has been specifically created for me and my dietary needs, thanks to Marcin I’ve discovered that losing weight isn’t just about “chicken and rice” lol.
Would highly recommend if you’re serious about changing your lifestyle.

Highly recommended

I have worked with Marcin for about 3 months. I must say it's an incredibly positive experience. Marcin's knowledge and expertise were evident as he carefully listened to my concerns and goals. He provided me with a personalized meal plan that was both realistic and effective. Throughout the process, Marcin's support and encouragement were invaluable, and I felt motivated to stick to the plan. Thanks to his guidance, I have already noticed positive changes in my overall health and well-being. I highly recommend Marcin to anyone in search of a knowledgeable and supportive nutrition coach.

I initially intended to train with Marcin for a maximum of one month, but here I am, two years later, and I could not be happier with my decision. My growth during this time has been amazing, and I've done more than I ever thought I could. The session plans are thoughtful, engaging, and personalised for you.

Always uplifting and ready to chat, I would definitely recommend him to anyone looking for a trainer and diet planning. Thank you!

I have been working with Marcin for 4…

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.
