My name is Shanon Christopher Williams, and I?m going to show you which punching bag you should buy based on your body weight and skill level as well as how to properly use it. But first, let me tell you a little bit about my experience. I?ve been training in various martial arts and Hapkido for more than 12 years now. One crucial aspect to any martial art is the development of power through the use of the punching bag. In the time frame of hours, I have racked up close to 400 hours on the punching bag alone, so I know a thing or two.
