Wearable fitness apparatus using elastic cable

A wearable fitness apparatus comprising:

• a base plate configured to be worn at least on a back of a user;
• a driving module comprising a module case and a motor, the motor disposed inside the module case, the module case detachably connectable to the base plate and, while attached, translatable along and rotatable relative to the base plate;
• a cable pair including an inelastic cable driven by the motor and an elastic cable;
• a wearing part, comprising a band and/or strap, configured to be worn on at least a limb of the user, wherein the wearing part is connected to the elastic cable and is connected in series between the inelastic cable and the wearing part;
• a plurality of sensors including at least an inertial measurement unit, a pulse sensor, and a tension sensor configured to sense a state of the user and measure tension applied to the elastic cable;
• and
• a controller, comprising processing circuitry, configured to identify a type of an exercise performed by the user based on information regarding the sensed state and information regarding the measured tension, and to perform force feedback control of the motor so that tension in the elastic cable follows a selected load profile corresponding to the identified type of the exercise.
