1. A resistance training machine comprising:
a base situated parallel to the floor;
a power supply;
a left motor and a right motor, each including an integrated motor encoder and an integrated motor controller;
a left pulley system and a left geared system configured to operatively convert torque from the left motor to a constant force or a constant velocity on a right cable;
a right pulley system and a right geared system configured to operatively convert torque from the right motor to a constant force or a constant velocity on a left cable;
the left cable operatively coupled to the left motor and running through the left pulley system;
the right cable operatively coupled to the right motor and running through the right pulley system;
a machine controller configured to control the left motor and the right motor and to receive position and torque feedback therefrom; and
a human machine interface in bi-directional communication with the machine controller;
a left drive belt configured to transfer torque from the left motor to a left drum pulley; and
a right drive belt configured to transfer torque from the right motor to a right drum pulley;
wherein the left cable is fixed to the left drum pulley and exits from a left pulley housing located on the base;
wherein the right cable is fixed to the right drum pulley and exits from a right pulley housing located on the base;
a plurality of load cells located in the base and in communication with the machine controller;
wherein a user performs each workout on top of the base;
wherein the load cells operatively supply user balance feedback through the human machine interface;
the machine controller receives position feedback and force feedback from the left motor and the right motor and communicates feedback and balance feedback to the user through the human machine interface;
wherein each of the left motor and the right motor receives a CAN signal or a PWM signal from the integrated motor controller; and
wherein each of the left motor and the right motor is capable of independently operating at a constant current, operating at a constant position, operating at a constant velocity, and implementing a received motion profile;
wherein the resistance training machine provide isotonic exercises with the constant force on the right cable and the left cable, provide isokinetic exercises with the constant velocity of the right cable and the left cable, and communicate user form feedback and user balance feedback.
