About Us
We are Matthias Kegelmann and Niki Karagiannis—two personal trainers from Basel—and we’ve made it our mission to truly help people improve their fitness, health, and quality of life through simple yet effective training.
Our Philosophy
We believe in the long term. Not in crash programs, miracle cures, or quick results that disappear after three months. We want our clients to still be working out ten years from now—and to be even fitter than they are today.
We’re aware of how much social media can distort our self-image, so we focus on setting realistic expectations—not the fantasy of a 20-year-old who has nothing to do but work out every day and post photos that show them in the best light. Those are influencers.
That means: a solid plan, proper technique, honest feedback—and support that doesn't end after the first session.
MATTHIAS KEGELMANN
Through his own training, Matthias discovered a passion that he didn't want to keep to himself. What drives him is helping people discover what their bodies are capable of—and putting that into practice systematically, consistently, and with genuine joy.
His strengths lie in one-on-one personal training, calisthenics and handstand coaching, and integrating training with nutrition. What his clients particularly appreciate about him: patience, clear instruction, and long-term support rather than short-term motivational boosts.
