ABSTRACT:
An exercising apparatus has a hollow housing with an aperture extending therethrough and a cavity on one side. The cavity has a cylindrical portion and at least one slot portion extending outwardly at the edge of the cylindrical portion. A first handle is connected to the housing. An axle, with a round portion and a square portion, extends rotatably through the aperture. A bolt extends through a longitudinal aperture through the axle. The round portion of the axle extends through a pulley wheel in the hollow housing. There is a one way clutch between the pulley wheel and the round portion of the axle. A strap, normally wound about the pulley, wheel extends from an opening in the housing. A spiral spring within the housing biases the pulley wheel to wind the strap. There is a set of at least three friction discs proportioned to fit freely and removably within the cavity of the housing. A rotatable metal disc has a square central aperture for rotation with the square portion of the axle. A non-rotatable metal disc has a round central aperture and an outwardly extending projection shaped to fit within the slot portion of the cavity. A leather disc between the metal discs has a round central aperture. There is a knob threaded onto the bolt to compress the friction discs between the knob and the housing. The knob is removable to permit the set of friction discs to be replaced.
