An instrument similar to the horizontal spiral, with the difference that in this exercise greater involvement of the upper limb is required.

In addition to the prone-supination movements of the forearm, in fact, movements of the arm must be associated, which must guide the hand in the twisting movements. The aim of the work is to exercise the upper limb in a complex movement that requires a good level of skill and motor fluidity.
