I've recently started getting back into boxing again and I've noticed I keep over extending my right hand when punching, putting me off balance slightly. However, I'm fine when throwing the punch when I can see myself in a mirror during shadow boxing. I was just wondering if anyone had any ideas as to how to stop myself over extending the punch each time?
Need a video. It may be your right foot position or you are bending your body forward too much or even your shoulder movemet during the punch, so I won't state anything without seeing t.
I'm no expert but it sounds like a depth perception problem...assuming that you're throwing the punches correctly. The better you get at judging distance, the less you'll have to overextend when throwing a punch.
You are trying to punch with your arm. Focus more on the pivot and turning your hip, let your arm come out naturally and keep your torso straight.
