Optimise Your Performance

The Inner Game Journal

was created to help athletes understand themselves through daily assessment. Athletes will learn what their optimal routine is to improve their performance on field. 

Founder, Stefan Mauk spent years combining the information he learned from books, psychologists, podcasts and experiences to create his own journal. He strongly believes the Inner Game Journal encompasses the best parts of all his learnings to help you be the best version of yourself.

“The Inner Game has helped me immensely, both for performance and for the mental health aspect. Getting my thoughts and feelings out of my head and onto paper allows me to let go and to move forward”
