Abstract

An apparatus for improved arm and leg gymnastics, characterized by being constituted by a rigid, preferably tubular frame in which three branches are terminated, that is: a center slightly inclined in an upward forward direction; another posterior one inclined towards the back with an upward orientation; and another front, shorter than the previous one, also oriented upwards. The rear branch of said frame is supported by plug at its end with possible penetration graduation, the cylindrical base of a saddle and has coupled, one on each side with symmetry, respective posts that after fixing, are curved determining a corresponding straight section inclined downward with outward and backward orientation whose end is bent in turn determining a shorter end straight section, orthogonal to the ground, constituting the rear legs that can be topped by corresponding non-slip ends. The front branch of the frame that faces upwards is a short rectilinear section, it is supported by uprights that are fixed to it parallel and symmetrically, which open outward and forward to curl again ending with a small section orthogonal to the floor that is constitutive of the front legs that can also be protected by non-slip sockets, the particular circumstance being that in the part of the frame where the two symmetrical front uprights are fixed, two squares are also fixed, also symmetrical, whose corner angles protruding or free support the axis of rotation of a rectilinear tubular element, whose two thirds higher than approximately its length, form the upper arm of a lever on the upper end of which are parallel and symmetrically coupled two tubular branches that open slightly in u to bend outwards p or its ends at 90º constituting a handlebar that can carry its corresponding hard wrist, and the remaining third of said tubular element constitutes the other arm of the lever whose end is subject to the action of a spiral spring that has its other opposite end fixed in a sleeve mounting in the rectilinear central part of the frame, which sleeve is also support for a bearing in which bicycle pedals are coupled, a braking system of said pedals being provided, according to known technique, in order to increase the difficulty of pedaling by the user.
