My Master/Sensei/Coach has us doing press ups every lesson, and stresses the importance of narrow grip press ups over the traditional variation. He rationalizes it as narrow grip press ups more accurately mimic the dynamics of a proper punch, as well as developing more applicable explosiveness/strength in grappling. So Question # 1: Is this rationale justified? It got me wondering something else as well. If narrow grip press ups more accurately benefit punching power and endurance, then maybe narrow grip benching will also be more applicable in gaining greater punching strength. So Question # 2: If the previous answer (to question 1) was "yes", would you go as far as to advocate narrow grip benching when seeking to increase punching power. PS - I am well aware of the fact that it is believed that punching power is derived from increasing general strength levels. However, given everything else remains constant (you continue squatting, dling and benching), would adding narrow grip benching to your routine be justified by the aforementioned rationale?
