         3 . The fitness training device of  claim 2 , wherein the force to be applied to the connector cable is greater than the first force applied to the connector cable during the first portion of the fitness action. 
     
     
         4 . The fitness training device of  claim 2 , wherein the force to be applied to the connector cable is equal to or less than the first force applied to the connector cable during the first portion of the fitness action. 
     
     
         5 . The fitness training device of  claim 1 , further comprising:
 an accessory configured to connect to the connector cable, the accessory operable to be manipulated by a user to perform the fitness action.   
     
     
         6 . The fitness training device of  claim 5 , wherein:
 the first portion of the fitness action corresponds to an unwinding of the connector cable from the cable drum spool; and   the second portion of the fitness action corresponds to a winding of the connector cable around the cable drum spool.   
     
     
         7 . The fitness training device of  claim 6 , wherein:
 the cable drum spool, the motor, and the controller are located within an electronics module; and   the electronics module is at least partially located within the housing.   
     
     
         8 . A method of controlling a fitness training device, the fitness training device including a connector cable, a motor, and a controller, the method comprising:
 controlling, using the controller and during a first portion of a fitness action, the motor to limit a speed for a motion of the connector cable;   recording, using the controller and during the first portion of the fitness action, motion parameters associated with the motion of the connector cable;   determining, using the controller, a force to be applied to the connector cable based on the motion parameters associated with the motion of the connector cable; and   controlling, using the controller and during a second portion of the fitness action following the first portion of the fitness action, the motor to apply the force to the connector cable.   
     
     
         9 . The method of  claim 8 , wherein the motion parameters associated with the motion of the connector cable include a first force applied to the connector cable during the first portion of the fitness action. 
     
     
         10 . The method of  claim 9 , wherein the force to be applied to the connector cable is greater than the first force applied to the connector cable during the first portion of the fitness action. 
     
     
         11 . The method of  claim 9 , wherein the force to be applied to the connector cable is equal to or less than the first force applied to the connector cable during the first portion of the fitness action. 
     
     
         12 . The method of  claim 8 , further comprising:
 unwinding the connector cable from a cable drum spool during the first portion of the fitness action; and   winding the connector cable around the cable drum spool during the second portion of the fitness action.   
     
     
         13 . The method of  claim 8 , further comprising:
 determining a velocity of the connector cable; and   limiting a rate of change increase in force on the connector cable based on the velocity of the connector cable.   
     
     
         14 . The method of  claim 13 , further comprising:
 limiting a rate of change decrease in force on the connector cable based on the velocity of the connector cable.   
     
     
         15 . A fitness training device comprising:
 a housing;   a cable extending through a cable aperture in the housing;   a motor operable to apply a force to the cable to control a motion of the cable; and   a controller including an electronic processor and a memory, the controller configured to:
 record, during a first portion of a fitness action, motion parameters associated with the motion of the cable, 
 determine the force to be applied to the cable based on the motion parameters associated with the motion of the cable, and 
 control, during a second portion of the fitness action following the first portion of the fitness action, the motor to apply the force to the cable.
