Abstract:
A multifunctional exercise device comprising:a base formed of a seat and a plurality of rod members; an arm-building mechanism mounted on said base having a pull rod engaged thereon so as to bring about a pivoting action relative to the base; a leg-building mechanism and said arm-building mechanism, both being engaged to a bias rod, such that said two mechanisms work together; and a weight unit disposed on said arm-building mechanism and formed of a plurality of weights to bring about a damping effect; wherein said arm-building mechanism comprises two fitting members which are symmetrically disposed on a top of said base and are each formed of two support rods located at different levels for retaining said pull rod, each of said two fitting members being pivotally engaged to a connection rod which is in turn pivoted to the bias rod; wherein moment of force brought about by said leg-building mechanism in relation to a pivoting point thereof is greater than moment of force brought about by said support rods of said arm-building mechanism in relation to pivoting points of said support rod; and wherein said weight unit comprises a resistance rod and a plurality of weight, with said resistance rod being disposed on said bias rod, and with said weights being fitted over said resistance rod.
