I’m John-Marco, but most people call me John
I’m an MNU-certified nutritionist and certified personal trainer who helps you build confidence, competence, and independence in your health and fitness.

I have had the pleasure of working with some wonderful people
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.

Steffen Fossbakk
John-Marco is amazing at providing support, offering solutions, and making those he speaks with feel safe. He shows great understanding and possesses so much knowledge about things most people wouldn’t even think about.

Desiree Gjessing
I especially appreciated John-Marco’s support and encouragement, willingness to listen, and ability to accommodate my physical and mental challenges. His presence and curiosity in exploring new challenges to find solutions were unique.

Shiva Seifi
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.

Laila Thomassen-Paulsen
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.

Kenneth Kvalvik
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.

Therese Paulsen
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.

May-Lill Klaudiussen
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.

Eivind Figenschau
Being able to collaborate with a PT who truly listens to my goals, provides a safe environment for honest conversations, delivers great sessions, and gives solid explanations to questions along the way has given me immense confidence during my journey into the fitness world.
From being a person who has tried to start a strength-training lifestyle and fallen off countless times over the years, to having managed to stick with it for a year so far, is all thanks to my journey with John-Marco as my PT. My confidence when I walk into the gym now is completely different, thanks to my great training programs and education on performing well-thought-out exercises, without fear of poor technique or the risk of injury.

Hi, I’m John-Marco Ariza
Early in my career, I noticed that people came to me for guidance on topics beyond exercise. These were areas I didn’t yet have the confidence, knowledge, or skills to support them. My curiosity and desire to help people further drove me to attend workshops and conferences and complete courses, including Mac-Nutrition Uni, a world-renowned, evidence-based nutrition qualification.
Through what I have learned, I have developed a strong appreciation for evidence-based practice, which guides my work today. I guide and support individuals by using the best available research and my experience, while considering their needs, values, and preferences, to achieve what matters to them.
How I can help you
Whether you are new to exercise, unsure where to begin, or have experience but have realized you could benefit from guidance and support, we’ll work together to help you build confidence, competence, and independence in your health and fitness through guidance in training and nutrition.
As your confidence and competence grow, we can adjust the level of guidance and support to reflect your changing needs.

How we’ll work together
Every collaboration begins with a conversation. It starts with an inquiry, where you let me know how I can help. Once you’ve submitted your inquiry, I’ll be in touch and send you your pre-consultation form. The pre-consultation form allows you to tell me more about yourself, your goals, and your current circumstances, while helping me understand where guidance is appropriate and whether I’m the right person to help.
If we decide to move forward with our collaboration, we’ll schedule a consultation. Building on what you’ve shared, we’ll further explore your goals and circumstances and develop personalized plans and recommendations to help you move forward.
