A significant number of resistance training injuries occur at the shoulder complex. However, there is a lack of research identifying predictive variables, which may increase the risk of these injuries. Certain exercises, such as those requiring the apprehension position (glenohumeral abduction with external rotation), have been investigated and found to be associated with shoulder pain and injury. However, there are additional exercises or positions that may also be associated with increased injury risk. The position of end-range glenohumeral extension, particularly as it pertains to a dip, is a vulnerable position that may have previously been overlooked.
