1. A strength training apparatus comprising:

  • a base member;

    a tower coupled to and extending vertically upward from the base member;

    a first arm coupled with the tower;

    a first pulley coupled with the first arm;

    a first handle coupled to the first pulley;

    a second arm coupled with the tower;

    a second pulley coupled with the second arm;

    a second handle coupled to the second pulley;

    a third pulley;

    a biasing member coupled to the third pulley and coupled to a first fixed location on the tower, the biasing member configured to stretch in order to allow the third pulley to be displaced vertically relative to the tower and configured to retract in order to cause the third pulley to vertically return relative to the tower;

    a fourth pulley rotatable about an axis that is fixed with respect to the tower;

    a flywheel;

    a clutch mechanism coupled to the flywheel, the clutch mechanism configured such that rotation of the clutch mechanism in a first direction drives the flywheel to likewise rotate in the first direction, the clutch mechanism further configured such that reversing rotation of the clutch mechanism to a second direction that is opposite the first direction has no effect on the rotation of the flywheel;

    a drive cable coupled to the first handle and the second handle, the fourth pulley, the clutch mechanism, and the third pulley, the drive cable configured such that a user pulling on the first handle and/or the second handle causes the drive cable to rotate the clutch mechanism in the first direction and causes the drive cable to stretch the biasing member and thereby vertically displace the third pulley relative to the tower, the biasing member configured such that a user releasing the first handle or the second handle, after pulling thereon, allows the biasing member to retract, thereby causing the drive cable to rotate the clutch mechanism in the second direction and causing the third pulley to vertically return relative to the tower;

    a sensor configured to take measurements during the rotation of the flywheel; and

    a control panel including an input device and an output device, the control panel being in communication with the sensor, the control panel configured to calculate an amount of power expended by the user pulling on the first handle and/or pulling on the second handle during an exercise session based at least in part on the measurements taken during the rotation of the flywheel, the output device configured to provide an indication of the calculated amount of power expended by the user, the control panel further including a connection configured to communicate with another device.
