During weightlifting, a lifter strains to complete a bench press rep. Which failure mode becomes likely when the force demands exceed the biomechanical limits of the shoulder joint?

💡 Explanation

Glenohumeral joint subluxation is likely because the extreme forces overwhelm the joint's stability mechanisms, especially the rotator cuff muscles and ligaments. Therefore, the humerus partially dislocates from the glenoid fossa, rather than increased bone formation or other joint-related adaptive processes.
