For my capstone, I designed and prototyped a specialized gym pin intended for cable machines. This device solves a problem in bodybuilding and resistance training: the inability to perform smooth drop sets without interrupting muscle tension. Traditional pins require you to manually adjust weights between sets, which not only breaks the flow of a workout but also limits muscle engagement. My solution was to create a pin that uses a spring-loaded mechanism, triggered by an impact or button press, to instantly drop the weight and allow for better transitions. Along with it I designed a weight collar that holds weighted plates on a barbell. I made sure my designs were 3D-printer compatible so I can spread my work to the world rather than just make the devices. These devices are aimed at improving training efficiency and promoting better results, especially for beginners who may find equipment adjustments intimidating.
