The goal of this study is to find out if a tool called an external cueing device (ECD) can help young swimmers improve their shoulder function. An ECD is a tool that limits arm movement and gives the swimmer a target to focus on while doing exercises. The main questions this study will answer are: * Does using an ECD during certain exercises improve muscle strength? * Does using an ECD while exercising help with shoulder stability? Participants will: * Test their shoulder muscle strength and stability at the beginning of the study. * Complete 8 exercises as part of their regular dry-land training program for 6 weeks. * Repeat the same tests after 3 weeks and again at the end of the study.
