Construction
Punching bags are often filled with grains, sand, rags, or other material and are usually hung from the ceiling or affixed to a stand. Other bags have an internal bladder to allow them to be filled with air or water. The design of a punching bag allows it to take repeated and constant physical abuse without breaking. The bag must also absorb the impact of blows, without causing harm to the user.
