I know many members at my gym and one of them was talking to me a few years ago. He was always interested in my exercises and I would show him what I was doing. This time he asked me about Martial Arts. “If youwas attacked and only had one move what would it be?” I replied the kick because your leg reaches farther than your arm and it’s more powerful. The kick would also be a surprise to most attackers who are probably accustomed to fighting with fists only.
The negative thing about fighting with kicks is they take more energy than punches and I get winded quicker when I kick more in martial arts.
