Testing, training, recovery and longevity for executives, athletes and high performers in Zurich — one system, delivered in person and in the AG Performance App.
Trust the process. Built belief.
Every program starts in the same place — with a measurement, not an assumption.
Nothing is prescribed before it is measured. This is how every program runs, whichever door you come through.
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.


I don’t just coach performance. I test it first.Alex Grabher
At the heart of the A6 Athlete is something personal: I want to live what I coach. I test the practices I share through my own training, recovery and everyday routines, paying attention to how they affect my energy, focus, sleep and wellbeing.
Running ultramarathons and 820 km of the Camino de Santiago in two weeks have taught me a great deal about myself: how I respond when I’m exhausted and my mind tells me to stop; how much I rely on factors beyond performance, such as rest and the people around me; and when to keep moving versus when to listen more carefully.
That experience shapes how I coach. Your goals matter, and so does the life around them. Every protocol I give you begins with firsthand experience and is adapted to you as a whole person.
One app for everything you do with us — on your phone and on your computer. Book your sessions and services, follow your plan, train with Alex’s videos, track how you recover, and message your coach.

Apply for coaching and we build the program around you — or book a single service directly in the app: a test, a treatment, a tennis session.
