Training system including: a training machine including: a Magnet Rheological fluid (MR-fluid) load generating unit generating a load to be exerted on the trainee, by using an MR-fluid having a variable viscosity depending on a magnetic field strength; mechanical arrangements; a displacement detection sensor; a power-assisting motor; a storage unit configure to store MR-fluid load characteristic information on a relationship between a current through the MR-fluid load generating unit and the load generated by the MR-fluid load generating unit; and chain and sprocket arrangements.
