Thulin has owned and operated together with two partners, over the last three decades, 127 fitness centers throughout Scandinavia. With his knowledge of club management, devotion to exercise physiology, and grasp of engineering – in conjunction with the design help of a Swedish automotive team – Thulin brings X-Force equipment to the market.
The ingenuity of the X-Force machine is a patented, tilting weight stack that unloads the positive phase, and then, overloads the negative. X-Force equipment supplies negative-accentuated exercise – 40-percent extra negative resistance compared to the positive – without the use of assistants, in a series of 14 strength-training machines.
