Handy Gym works through two inertial discs which are capable of converting their turn in strength of resistance.
The secret is that the cone of this machine and the special epicyclic gear multiply 13,5 times the speed of the axis and reduce the disc mass 182,25 times and in consequence the weight of all the machine.
In terms of training and/or recovery efficiency the inertial technology is the top option thanks to its capability to offer an incredible concentric training, but also a very important eccentric training.
