I am a group fitness instructor at X, TU Delft, where I teach Body Power and XCORE. Two very different classes: one builds strength and stamina with a barbell and dumbbells, the other is fast, explosive core work with the XCO trainer.

What I care about in both is the same. Everybody in the room trains at their own level, technique gets coached rather than assumed, and the session is something you can come back to next week — not something you need to recover from for three days.

Beyond the studio I lead workouts at sports days, student events and community gatherings, and I am happy to work with other instructors, gyms and organisers.

Away from the gym I work as a software engineer, and I speak at software conferences across Europe — Devoxx, Voxxed Days, JNation and others.
