My story
For years, I climbed the corporate ladder. Meetings, Excel spreadsheets, PowerPoint presentations. I was good at what I did, but something was missing. Sport became my escape: first to decompress, then to push my limits. Climbing, triathlon, crossfit, trail running... Each discipline taught me something about myself.
One day, I realized that what truly excited me wasn't quarterly performance charts, but watching people around me grow. Seeing them regain confidence, hold a rhythm, find new energy. I left everything behind to create LTHR Coaching, now CRAN.STUDIO.
Today, I help people take back control of their body and health. No miracle promises, no extreme methods. Just smart work, consistency, and a lot of humanity.
"My goal is to help you make sport a natural habit, adapted to your life and desires."
