First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether a specific stretch called the sleeper stretch can help CrossFit athletes with shoulder pain move better and perform stronger. Twenty-six regular CrossFit participants were included, and researchers measured their shoulder strength and function. The goal was to see if this simple stretch could ease pain and improve performance without surgery or medication.
