The Mad King is the leg press for royal legs! And just as you can be proud of your thigh muscles, we are proud of our unique device.

As the very name suggests, the leg press is a strength fitness device designed to perform the leg press exercise and is a safe alternative to squats.

It is known that each person has a dominant side of the body, with which they are able to overcome a larger share of the load. Hence, the idea was born to design our device in such a way that the user can simultaneously – but at the same time independently – perform the leg press exercise first with one leg and then the other. Thus, the muscles in an individual leg can be completely isolated; this prevents the dominant leg from taking on most of the load, becoming even stronger and increasing the difference between the legs. This is also the biggest trump card or the biggest advantage of the device.

The device is made of profiles measuring 80 × 80, which have already been tested and are recognized as a KingsBox trademark. This way we maintain a common theme in our individual products and make sure that all our products in your gym work coherently. The profiles are connected by steel plates, which serve as an excellent connecting element and at the same time give the product the industrial and mighty look, which is a distinguishing feature in the KingsBox equipment.
