How to Fill Punching Bag

What do you fill a punching bag with? From this guide, you will learn how to stuff the bag properly in various ways for comfortable and safe training.

When I purchased mine I though I only need to throw some clothes into it and it is ready to use, but it is far from that. A poorly filled heavy punching bag gives an awful user experience plus it can be dangerous to your knuckles and wrist. Also, it does not swing suitably that is essential as well.

Typically, the biggest problem with a badly-filled bag is that the filling sinks to the bottom. This way the top will be soft and bottom rock-hard. Hence, you cannot the place punches correctly on it, and the bottom will kill your knuckles.

Furthermore, a too softly filled equipment will not provide correct resistance, while a too hard one might cause injuries in your wrist and knuckles.

There are four types of punching bag filling you can use: old clothes, sand, sawdust or you can buy special filling. You can also combine them.

Here we are only talking about the no-cost methods.


What to fill in punching bag?

The sawdust filling

For this method, you will need a few pieces of old clothes, sturdy rubble sack, and sawdust depending on the sizes of your heavy bag.

Firstly, place the clothes into the bottom tightly maximum to the 1/3 of the bag. Then, put the rubble sack and start filling it with the sawdust until it reached the sides of the heavy bag. If it is required use more than one rubble sacks to fill it entirely. And don’t forget to tightly close the mouth of the rubble sack(s). Do not put sawdust directly into the shell.

With this method, you can get a punching bag that is not so heard and heavy.

Clothes filling

For this method, you will only need old clothes. It is important to place the pieces of clothes very tightly each other. There should not be empty places, so the best is if you fold them before. If the clothes sink, add more clothes into the bag.

Even if you use clothes for this filling, if you do it right, you are going to have a medium heavy and hard equipment.

Sand filling for extra weight

The sand filling does not mean we fill the entire shell with sand. It would be hefty and hard. And I think no model in the world can handle such a huge weight. Plus, a punching bag with sand would be so firm that it would break your hands. Instead, we use it for making it heavier and more solid.


From the following video, you will learn how to do this method correctly to get a classic heavy bag stuffing that has a perfect shape and structure.


What is the best filling for punching bag?

If you ask me the best is if you combine the three heavy bag filler above. This way you can have equipment that will suit your need. If you require more weight and hardness use more sand. In case you need a lighter equipment then use more sawdust. And, if it is necessary, refill it regularly. In case you need equipment for kicks, then you may want to choose one from the standing punching bags.

Most of the people use water to fill the base of this equipment. However, you can also add sand to it. This way the base will be much heavier and with that equipment more stable.

I think, it is better to get a filled one since it is ready to use. If it is too light, you can put clothes or other materials whenever you want.
