What Is a Punching Bag? 

If you’ve ever entered a dojo or a gym before, then you’ve probably laid eyes on a punching bag. For those that don’t know, a punching bag is cylindrical in shape, it’s filled with fiber or foam (sometimes water), and is punched and kicked by all sorts of people.

Punching bags are used almost primarily to build muscle. However, you can use a punching bag as a means to release sweat and stress. The main types of punching bags are known as hanging and freestanding.

Types of Punching Bags

Although most gyms will have either a freestanding or a hanging punching bag (sometimes both), there are at least 6 types of bags you should know about. I’ll explain what they are below.



Freestanding punching bags are punching bags that sit atop a base. The base is not usually mounted onto the ground, so users can move the bag from place to place by lifting or dragging it around.

Hanging punching bags use a suspension system that keeps them mounted on the wall or rafters. This type of bag will usually hang around 1 foot above the ground, depending on the bag’s size and the length of the chains or ropes keeping the bag suspended.



If you want to work on the speed of your punches and reflexes, then you need a speedbag. These bags are filled with air, making them lighter than traditional punching bags. They’re attached to a spring system, which allows them to bounce back when struck.


Angled punching bags look almost exactly like hanging bags. The difference is the style—the surface is slightly angled to help users practice and perfect their uppercuts. It also comes in handy for basic kicking and punching training.


Grappling dummies are not bags in the traditional sense. Instead, they’re shaped like humans to give users a more realistic feel of what it’s like to take a human body to the ground. This speciality “bag” is mainly used for combat sport training.

How to Size a Punching Bag

It’s important that you choose a punching bag of the correct size. A general rule is that a punching bag should be at least half the user’s weight. So, if you’re 180 pounds, you should look for a 90 to 100-pound model to hit around.

Here’s a brief guide on who would benefit from different punching bag sizes.

  • 40 pounds—Ideal for youth boxers (13 years and under).
  • 70 pounds—Ideal for teenagers and amateur boxers.
  • 100 pounds—General-purpose weight, ideal for intermediate-level boxers.
  • 200 pounds—Ideal for heavyweight boxers or experienced gym rats who want to build upper-body strength.

If you’re going to get a hanging punching bag, you should also consider how strong your rafters are in keeping the bag up off the ground. For those that don’t want to risk significant damage to their property, perhaps a freestanding punching bag fixed to the ground would be the better option.

Punching Bag Alternatives

Shadow boxing

Focus Mitts

Focus mitts are specialized gloves that a partner or trainer wears. The goal of focus mitts is to strike them, giving you a realistic feel of how opponents move in the right. The resistance of focus mitts depends on the strength of your partner, so they’re mainly used to improve accuracy.

Wrist Weights

For those that want to improve arm strength, speed, and endurance, you can remove punching bags from the equation and shadow box with wrist weights instead. These simple tools are worn as gloves or bracelets that strap around your wrist. Their main purpose is to add resistance to your arms, so you have to actively use muscles to lift and strike with them strapped on.
