Advantages / Comparison

The new resistance device is superior to traditional weight stack devices in all of the engineering and operational aspects: ensures comfort of the user due to smooth lever motion (a change-over from the forward to reverse motion is imperceptible), noiseless operation, lack of clanking and jolting which are common to weight stack devices.

1) The absence of inertia results in better injury prevention for the user and a higher speed of exercise (limited only to user's speed).
2) The resistance level is sustained at a constant value with high accuracy (1.0%) during exercise performance.
3) It has a wider choice of resistance settings with its 2.5 kg (5.5 lbs) steps, starting from 2.5 kg up to the maximum resistance level.
4) It reduces the overall device weight (by 60 kg and more) which is of high significance, especially for home fitness machines.
5) It poses no restrictions on the speed of exercise, providing for a possibility of exercising at any desired pace, without detriment to the efficiency of the resistance (Functional training ready).
6) The new vacuum device enhances training efficiency by having superior dynamics and allowing performance of a greater number of sets over a given time span or by an appreciable reduction of training time. A weight stack training machine is unable match those characteristics. The reverse motion on a weight stack machine must be very slow to maintain an equal of resistance. If a user starts performing exercises at a high pace, first it will cut the efficiency since the reverse motion will be idle, the weights falling down without creating any resistance (an elevator effect), second, the probability of inflicting injuries increases sharply, because, once the weights reach the lowest point, the resistance level will jump up and exceed the mass of the weights.
7) The new device ensures psychological comfort and safety since the user can let go the training machine levers at any moment and be sure that unlike with a weight stack machines, there will be no risk of injury.
8) It has a wider spectrum of consumers, since these devices may be used not only in strength, but also in wellness and rehabilitation machines.
9) It ensures safety of the user;
10) It has a long service life (minimum of 15.000.000 cycles);
11) It only needs simple maintenance.
12) Does not require a pin to manually change the resistance level.
13) Can be implemented into electronic gaming environments.
