Claim 20:
21. A weightlifting system comprising:
a locking device comprising a locking face controlled by an electric solenoid, wherein the electric solenoid is configured to cause the locking face to be moved from a closed position to an open position, the locking device further comprising a receiver, the locking device being operable to lock such that a first portion of a flexible member extending through the locking device is fixed from movement in a first direction; and
a first trigger device positioned on a first side of a weight and operable by a user to send a first signal to the receiver to unlock the locking device such that the flexible member is free to move through the locking device; and
a second trigger device connected to a second side of the weight that is opposite the first side of the weight, wherein the second trigger device is operable by the user to send a second signal;
wherein the locking face is moved to the open position upon the receiver receiving the first signal from the first trigger device and upon a predetermined movement in a second direction opposite the first direction of the flexible member through the locking device, wherein the predetermined movement allows travel of the flexible member from the locking face when the locking face is in the open position.
