PowerCranks are, simply, independent bicycle cranks that replace the regular cranks found on a typical bicycle or exercise machine. This means one leg cannot help the other and in order to pedal the bike one cannot simply relax on the back stroke but must actively raise the pedal using your hip flexor and hamstring muscles. This simple change ensures that your leg muscles will become balanced (both right/left and fore/aft) and that you will be training additional muscles and coordination important to overall well-being and superior athletic performance. No other training tool does all of this.
Pare che facciano un gran bene !!!
Sia a livello riabilitativo/recupero da infortuni, che per migliorare la prestazione!! Costano solo un millino, quasi quasi le monto sulla spinbike ...
