Yes, my left hook is more powerful than my right hook. I have no idea why this is the case. Before I did boxing and MT, I did Xing Yi Quan (yes, kung fu), and it really helped train me to get my whole body behind a punch. As a result, my strikes are pretty "optimized", in my opinion as far as getting the body behind them. But my right hook is not as powerful as my left. I'm somehow not twisting my body correctly or making my spine too straight. Also, if it means anything, my right pec is smaller than my left, even though I'm right handed.
