Abstract: A portable spring loaded selector pin device comprising of an automatic release mechanism for use in performing intense weight lifting exercises involving reduced weight lifting sequences on weight lifting machines having weight stacks comprising of a plurality of weight plates. One or more spring loaded selector pin devices may be deployed, allowing the selection of multiple weight reductions to be preset. The spring loaded selector pin device utilizes the friction created by the weight plates to remain engaged while the weight is lifted, and automatically releases immediately after the weight is set down, making the next preset weight ready to be lifted without any interruption in the exercise.
