Active Pauses for Musculoskeletal Disorder Prevention in Workers

The goal of this clinical trial is to learn if short exercise breaks at work can prevent muscle and joint pain in workers. The main questions it aims to answer are: Do strength exercises help workers move better and feel less pain? Are strength exercises better than stretching exercises for worker health? Researchers will compare a strength exercise program to a mobility (stretching) program to see which one works better to improve physical health and work ability. Participants will: Perform short exercise breaks (5 minutes) at their workplace every day for 8 weeks. Attend one supervised session per week to learn the exercises. Complete simple physical tests (like standing up from a chair) and answer surveys about their health at the start and end of the study.
