To Guide You On Your Journey!


Workout of the Day’ is onze standaard les. Iedere dag is de workout anders en deze variabiliteit zorgt ervoor dat je fitness level over een breed spectrum zich ontwikkelt.


De Weightlifting les is voor degenen die specifiek aan de techniek voor het Olympisch Gewichtsheffen willen werken. Tijdens deze les is de focus op de Clean & Jerk en de Snatch.

Engine Room

De Engine Room is onze cardio les. Tijdens deze les is de focus op je aerobische vermogen en zullen de workouts doorgaans wat langer duren. Deze les is uitermate geschikt voor atleten die zich willen voorbereiden op Endurance evenementen zoals Hyrox.


Tijdens de strong (wo)man training ligt de basis in het ontwikkelen van kracht. Tijdens deze lange les worden trainingsmethoden van Strongman, Conjugate (powerlifting) en bodybuilding gebruikt om kracht op te bouwen en blessures te voorkomen. De les wordt afgesloten met een workout.

Nienke and Russel are focused on the community and its wishes. The range of lessons is very broad and diverse, and the programming is all-round. With coaching, they know how to give personal questions so that you learn in every lesson. A gym where, in addition to training, fun is certainly central and I feel very much at home!
