A self-spotting system for free weights enables the constructive use of such free weights without the need for a spotter. Using a free weight holder sliding along a rail, an adjacent free weight support provides and determines the lowermost travel of the associated free weight. In alternative embodiments, a parallelogram design for the free weight holder is set forth as well as a handle system which may optionally incorporate free weights and allow the use of the self-spotting system for single weights in conjunction with weights coupled to the handle system by a line or cable. Additionally, weight bar restraining and locking systems are set forth which provide secure means by which weightlifting bars can be secured into place, lowering the risk of slippage, dropping and the associated injury and damage that may occur when weights slip or fall.
