The power to adapt, like a chameleon. The 4E strength machine series is a completely new motorized series from Gym80 International. It consists of ten fully electronically-controlled training stations networked via the Gym80-Software. The heart of the package is the patented motor and technology. In the eccentric mode the motor recognizes the performance potential of the user and automatically sets the resistance levels. With 4E the user always trains at his or her natural limit and therefore, for the first time, the training is genuinely isokinetic. Members achieve their individual training targets.
