I train executives, athletes and high performers at their homes across Zurich — no gym required, no time wasted. One system, built around your life: the A6 Athlete's Core.
Trust the process. Built belief.
Most coaching adapts you to a program. I build the program around you — your calendar, your recovery, your goals. Fifteen years of coaching athletes and executives, tested at the most extreme level: I race ultra trails of 160 to 386 kilometres, and every lesson comes back into how I coach.

The A6 Athlete's Core is an integrated performance system. When every pillar is strong, everything elevates — for a CEO, a tennis player or a weekend athlete alike.
My journey started with one question: where are my limits? Today I race some of the hardest ultra trails on the planet — the Moab 240 through Utah's canyons, 160 kilometres across the Swiss Alps, the full Camino de Santiago in two weeks. Every race is a laboratory. What I learn at mile 140, I bring back to my clients in Zurich.
When I talk about nervous system control, sleep strategy or resilience, it's not theory. I've tested it in my own body — at hour 60, at altitude, at 3 a.m. on day three.
"Each session challenged us on a personal level, and I could really feel the progress day by day. Alex's energy, patience and passion stood out most. Already signed up for next year."David Schaefer — Retreat Participant 2026
