Background:-Idiosyncratic stress on the flexed elbow as the forearm is supinated is the traditional injury mechanism for a biceps brachi tendon rupture. Before and after an exercise, it is crucial to warm up properly and stretch to keep a fit body and prevent bursitis and tendinitis.

Purpose: - The main purpose of this study is to diagnose biceps tendinitis prevalence in body builders.

Study Design: -Descriptive cross sectional

Method: -A cross-sectional study is done on bodybuilders who use the gym. The four-month trial is completed. Simple random sampling is used to rate 318 bodybuilders. The OY fitness centres, Ginnastic Arena, and Revive gym are used to collect data. Those between the ages of 18 and 64 who are male bodybuilders and have a BMI between 20 and 30 are included. It employs the Yargason test. The PENN shoulder scoring system is also used.

Result: -All injuries in bodybuilding occur while the elbow is in flexion or semi-flexion. According to the study, the subjects' forearms were supinated at their injured sides. This study demonstrates that the majority of participants in the selected demographic had bicep tendinitis due to the incorrect angle and lack of monitoring.The majority of participants in the selected group who experienced serious complications are being treated and provided the appropriate care by a physician for better results.

Conclusion: -Dynamic stimulus to an extended elbow and supinated forearm during bodybuilding was characterised as a novel mechanism for bicep tendinitis from the conventional mechanism of a flexed elbow and supinated forearm.
