Punch Bags, Not People

If you ever decide to train in boxing, there is no doubt you will put in a lot of time swinging at a punching bag. Punching bags are a staple of boxing gym and dojos where people train in mixed martial arts. But how does a punching bag take so many hits without collapsing or breaking your wrist? This article will explain how a punching bag works.
Punching Bag Construction and Speed Bags

It doesn't always serve well to use a live sparring partner when you train in hand-to-hand combat sports. People aren't always up to the task of being constantly hit on a daily basis as you try to perfect your punching and kicking techniques. Punching bags work based on their construction and purpose.
Modern punching bags are made of similar materials as their predecessors. You can find punching bags filled with sand, rice or a man-made replica of those grains like pinhead-sized Styrofoam. Punching bags can also be filled with rags, water or even air. The outside of most punching bags is made of tear-resistant vinyl or leather. In low-humidity areas, punching bags can be canvas-covered.
Regardless of their material makeup, punching bags have one function: To take a beating without easily breaking themselves or injuring the puncher.
The boxer's speed bag helps the pugilist develop accuracy and speed. It is usually filled with air but has a thicker punching surface. Speed bags are only about three feet long and are usually hung at the boxer's face level by a single hook. The boxer rhythmically strikes at the bag, trying not to miss as the speed bag bounces off of a board.

Other Types of Punching Bags

The heavy bag is usually hung from a ceiling with a thick steel chain and hook set. The bag will be about four feet in length and can be filled with anywhere between 50 and 150 pounds of material. The heavy bag's purpose is to provide enough resistance so that your hands and arms get used to hitting an opponent. Body bags help make your arms strong by providing this resistance. They can also assist in improving technique because if you punch or kick incorrectly you will feel the pain in your joints.
There are other more specialized punching bags that have been developed in recent years. Reflex bags are constructed to increase your reflex speed by providing a "moving" target. Reflex bags look like a speed bag attached to a microphone stand with a bend in the middle of it and a secure base. As you punch the bag, it snaps back and returns quickly into place, usually in half a second.
