The traditional bench press (TBP), performed with a grip width that maximizes strength, is popular exercise for developing the upper-body. close-grip (CGBP) variation of TBP often used to emphasize triceps brachii over prime movers such as pectoralis major. An individual’s arm span (AS; distance between middle fingers each hand while arms are outstretched) could affect mechanics exercise, which may be exacerbated by change in grip. This study investigated relationships AS and CGBP...
