Sidney is a personal trainer in the broadest sense of the word. With a study background at CIOS and at Menno Henselmans PT, he has not only a lot of practical experience, but also extensive theoretical knowledge.

Sidney is focused on strength and HIIT training, but understands that strength training alone is not enough to get the best out of yourself. To become and remain the best version of yourself, you must continue to develop yourself. This aligns perfectly with Athley’s philosophy!

As a trainer, Sidney looks not only at your physical performance, but also at all other factors that affect your training results. His holistic approach, backed by a scientific background, makes Sidney’s workouts both challenging and complete.
