Our mission is to inspire and challenge young global citizens from all over the world and be their friend on their most important adventure – their life!

Upotential was founded 2019 in Stockholm, Sweden by Catrin Eriksson and Marianne Marescotti.
United by a clear vision to contribute to a healthier and more fun world, the idea of establishing an inspiring arena for personal development and mental fitness was born!

The main idea behind The Gym for Mental Fitness was, and still is, to be a training club for people wanting to optimize life! We believe that it should be just as natural and easy to go to the mental gym and work on your brain, mind and emotions as it is to go the gym and work on your body.

So, our goal is to make mental fitness training simple, available and inspiring and we hope to become that innovative addition to personal development that makes mental fitness a natural part of people’s daily lives.

The founders


“I love to challenge my body through various sports and physical adventures! This curiosity and drive has made me reach accomplishments I never thought possible. When I did my Ironman I was prepared to the teeth, physically in top shape. But what really made the difference and what made me smile that last part of running a marathon was my mental toughness. I could never have done it without being in mental shape. And if I can do it, others can too! Now, I use all my stubbornness, focus and curiosity to actualize my dream by spreading the power of mental fitness and thereby contribute to a more healthy and passionate world!”

Catrin has among other achievements finished an Ironman, 4 x marathons, 1 x “en svensk klassiker”, 6 x Vasaloppet one of the longest cross-country ski races in the world, 2 x Marcialonga.


“As a former professional tennis player I was never the best technically or the strongest physically, but my winner mentality and my mental toughness took me really far. However, what I didn’t understand at the time was that in order to reach the stars and perform at the highest level for a long time, you need to cure your passion and recognize what effects the other parts of your life will have on your life. To reach the top, it’s simply not enough to only focus on performance; you need a deeper understanding of yourself and who you are. Now, older and wiser I will use all my mental power to build the most innovative and cool mental fitness gym in the world – so that ambitious people everywhere will have a place to train their mental fitness regularly”.
