The balance between motivating and pushing me and making me believe in myself was invaluable. I didn't get yelled at or lectured for skipping a workout, eating frozen pizza, or indulging in too many sweets. Instead, I was met with understanding and insightful responses that I found motivating.

John-Marco is a very supportive person who explains and guides exceptionally well. I learned so much and always felt like the center of attention. He helped me feel confident in resistance training. No matter how I felt that day, the training was always adapted so that I left with a feeling of accomplishment.

I'm very pleased with my collaboration with John-Marco. It was great to get guidance from someone with solid knowledge about training and nutrition. It gave me the insight I needed to be able to continue more independently afterward.

John-Marco was there for me on a professional level and, not least, a personal level. I always appreciated that I could share my thoughts and challenges relating to my personal life and resistance training.

My PT sessions were crucial in getting my body to function properly again. During our sessions, we discussed many of my thoughts and questions about training, dietary challenges, and life in general.

From being terrified of stepping into the weight room in 2018 and struggling with low self-esteem and confidence to when we finished working together in the spring of 2023, I have grown into someone who feels secure in my training, understands my own limits, and has gained an enormous amount of knowledge about nutrition and fitness. This journey has indeed contributed to my personal growth!
