What goes inside a punchbag?
Have you ever considered using a punchbag as part of your fitness routine? If so, you are not alone, as this is one of the most popular pieces of sporting equipment that we sell at Sports Maxx. You may think it’s just a matter of hanging a bag, and off you go, but perhaps the most important thing to consider is your punching bag fill.
In the UK, more than 494,000 people use boxing as a form of exercise. This is made up of those who take part in the sport itself and many others who see the merits in the various training workouts that the sport offers. Using a punchbag within a workout routine has been common practice since 688BCE when the Ancient Greeks first popularised this training method. We can see why it is so popular, as using this piece of boxing equipment offers a full-body workout that focuses on strength, agility, and mental responsiveness.
At Sports Maxx, we are boxing experts with more than 100 different punching bag products to choose from. Selecting the right bag for you is one thing but knowing what to fill it with to benefit your workout is something else that should be considered. This blog post explores the hard-hitting world of punchbags in more detail.
What fillings go inside a punchbag?
One of the most significant benefits of using a punchbag for a workout is that you can tailor the weight that it is suitable for by using different fillings. If your filling is not right, then a sub-standard training session may follow. It is not just your performance that will be hit below the belt because using the wrong type of filling could also result in an injury occurring.
Using the wrong filling for the type of punchbag that you have selected could also result in an ill-performing product that will not swing or move correctly. It is, therefore, essential to get the filling right!
As far as the ideal weight is concerned, it is recommended that a punching bag weighs half of your body weight. Using a weight that is too small for you could mean that your workout is not as beneficial as you think it is. However, using a weight that is too heavy could cause injury and make things a lot harder than they need to be. Whilst we think that sport should, of course, push you to your limits, it also needs to be safe and enjoyable.

How do I fill my punching bag for lightweight boxing needs?
For lightweight boxing needs, we recommend that you use a softer and less dense filling such as cloths, fabrics, or even foam. Using materials items mean that you can pack out the bag evenly and spread the weight to provide a weight that is suitable for either lightweight professionals or those who are just getting started with using boxing as part of a workout routine.
If using fabrics, we always recommend cutting them into even strips and removing any hard surfaces so as not to cause any damage to the punching bag.
The beauty of filling your own punching bag is that you can amend the weight when you need to. If you are using a lightweight, suitable filling, you may want to add more items or heavier fabrics as your skills increase. This lets you measure your development and means that you don’t have to pay out for a new product every time your skills improve.
How do I fill my punching bag for heavyweight boxing needs?
If you need to fill your punching bag to make it suitable for heavyweight punches, we recommend using sand or other smaller, densely packed items. Sand is favoured as it provides an even heavy weight which is perfect for punching but still allows a swing momentum to be achieved.
Just because these are the main materials used to fill punching bags doesn’t mean you cannot get creative. If you create an even filling suited to your weight class, you will be landing winning hits in no time.
For these items, we recommend placing them in smaller bags to stop any spills from happening. If you want to do this precisely, you could weigh out each one so that you always know how heavy your punching bag is. This is important not just to professionals but also amateurs who are looking to improve their overall fitness.
What are the benefits of using the correct punching bag fill?
With 41% of gym goers saying they have been injured by when trying to reach their fitness goals, it is super important that your punching bag is suitable for your own needs. We think that boxing offers a superb workout, but it is, of course, a very physical activity to take part in. This means the chance of being affected by an injury is much greater.
The benefits of educating yourself on the right filling to use for your punchbag are:
- You are less likely to receive an injury. Boxing puts great pressure on joints, hands, and arms, so working out safely within the sport is essential. In fact, 17% of boxing injuries are received by hands. Whilst trying to push your limits could be tempting, we think working out safely lets you achieve better results.
- Knowing what filling materials work best for you means you can swap out your punchbag weight whenever you need to. If you make the transition from lightweight to heavyweight or want to mix up your workout, there is no need to pay out for additional equipment.
- You can achieve a professionally accurate workout routine at home. Over 50% of people have done a home workout since 2020, so we certainly are a nation of living-room workout lovers! Knowing how to use your punching bag properly will take your workout to the next level. Move over Joshua!
