Punching bag

[2] Similar apparatus in Asian martial arts include the Okinawan makiwara and the Chinese mook jong, which may have padded striking surfaces attached to them.

[3] Punching bags are often filled with grains, sand, rags, or other material, and are usually hung from the ceiling or affixed to a stand.

Almost all punching bags are covered with either leather or synthetic materials such as vinyl which resist abrasion and mildew.

In this method the user may perform many diverse punching combinations that create improvised rhythmic accents.

Designed so that downward pressure stabilizes this portable speed bag platform, it can be installed and removed through a tension system that allows for use in any doorway.

The harder and faster these bags are hit, the more they rebound and react in different motions and angles, thus giving broader practice to the fighter.

The base is typically filled with sand or water to give more stability to the bag and prevent it from moving around.

[6] Other variations on the standard heavy bag include horizontal suspension from both ends to practice uppercut punches, and non-cylindrical shapes.

These bags try to simulate a live opponent while providing an opportunity to practice vital area strikes which are generally unsafe to perform on a sparring partner.

Large inflatable balloons with weighted bases are another kind of punching bag, often painted with a picture and sold as a children's toy.

Powerful strikes to the heavy bag are not recommended for inexperienced, or younger athletes (<18 female, <21 male), as risk of sprain, strain, or bone-plate damage may adversely affect bone structures.
