The apparatus has an adjustable rigid metallic frame (1) that is adjustable. Upper pedals (2) are fixed on a rigid tube that slides in the upper part of the frame (3). The pedals are turned by the hands of the user that are put into two loops (7) at the end of straps. The upper pedals are joined to lower pedals, that hold the lower limbs of the user, by a chain that transmits the movement to the lower pedals. A tensioner (5) and a wheel allow the chain to be adjusted and make the peddling more natural.
