1. An exerciser comprising:
- a supporting frame having a base with opposite front and rear ends, and an upright post that extends upright from said front end and that has a top end;
a lever having a pivot end that is pivoted to said top end of said upright post so as to permit rotation of said lever relative to said supporting frame, and a free end that is opposite to said pivot end, said lever extending from said upright post in a first transverse direction relative to said upright post;
a resistance providing member interconnecting said supporting frame and said lever so as to provide resistance to rotation of said lever;
a pulley mechanism including an upper pulley unit mounted rotatably on said free end of said lever and including at least an upper pulley, and a lower pulley unit mounted rotatably on said supporting frame, disposed below and aligned with said upper pulley unit, and including at least a lower pulley; and
a string having a free end, and a fixed end that is fixed to said supporting frame, said string extending upwardly from said fixed end to said upper pulley, passing over said upper pulley, extending downwardly from said upper pulley to said lower pulley, and then passing under said lower pulley so as to permit rotation of said lever when said free end of said string is pulled away from said pulley mechanism.
