Upotential is founded by us, Catrin Eriksson and Marianne ”Maja” Marescotti.

We believe that anything is possible and that people are powerful beyond measure and can live the life of their dreams. Our mission is to make a true difference in people’s lives through mental fitness training.

January 2019, not knowing each other yet, we were both looking for a place to develop our mental fitness skills; some place new and exciting that could inspire us to reach further. Neither one of us could find anything that even remotely represented that special thing we were hunting for.

Fate had it and people who saw that we shared the same vision connected us. We met, the stars were right and magic happened. We knew right there and then that coming together with our energy; stubbornness and drive could make a true difference in people’s lives. Said and done, we started building Upotential – the gym for mental fitness!

We decided from day one that we wanted to do things our way and always stay focused on being action oriented – simply learn by doing. We find this mindset priceless and that trying things in real life, being open to feedback and reflect on experiences are the things that keep us developing continuously and going forward at high speed.

Mental fitness training will make a true difference in people's lives! 

We know that people have much more potential than what they imagine and that everyone can live a successful and meaningful life, defined by them – but it takes hard work. Being mentally fit is simply put a lifestyle – 24 hours a day, 7 days a week, 365 days a year.

We decided that we had to create the most inspiring arena for mental fitness training in the world. To do this we’ve put together the best methods and tools from coaching and sports- and performance psychology in a unique mental fitness training program.

Our goal is to create a movement for all people who want to reach their full potential and at the same time live a meaningful life. We simply want as many people as possible to live the life of their dreams.

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”.

Maja reached a WTA ranking of 283 in singles, has won the Swedish championships 15 times (singles, doubles, junior) and finished her career off with a great college career representing UNLV; where among other achievements she was elected National Rookie of the year, Nevada Woman of the Year and her schools most valuable athlete two times, elected hall of fame 2008.
