Staal&Kracht is a small but a powerful gym, founded in 2008 with a focus on group classes, small group training, personal training and overall strength and conditioning classes in Rotterdam. Using kettlebells, sandbags, and bodyweight training.
Over time, it evolved into a free weight equipped indoor facility in 2013, expanding into powerlifting and strongman training with the right tools and environment to support serious strength development. Staal&Kracht became the first gym in Rotterdam and outer regions like Schiedam at it to fascilitate these disciplines of strength sports.
​
In the last few years the gym has also become a proud host of powerlifting competitions organized by the gym itself or under support of the Dutch Strength Federation under IPF regulations.
​
Now, Staal&Kracht stands at new crossroads — ready to grow further by introducing more specialized equipment, increasing the variety of group classes, and building on 17 years of experience in developing innovative training methods and physical challenges.
​
Staal&Kracht is located in a small industrial area between Rotterdam and Schiedam known for its past as glass manufacturing industry 'GlasFabriek' and currently as its Jenever distillery district, as well as the M4H district close to the Marconiplein towers called 'The Lee Towers' and the 'Floating Farm'. The gym is easy reachable by public transport, free parking and bycicle.
