One of the most common questions we come across in the store or in your posts on the site is how - and with what - to fill our punching bags. Here is our answer and our advice on this subject.
The first thing to say is that contrary to popular belief, you should not fill a boxing punching bag with sand. A cliché maintained in the collective imagination by literature and cinema with ancient pugilists training fiercely in gladiatorial fights on bags lined with stones which they reduced to dust. Another era or fiction...
Why don't you fill a punching bag with sand?
The answer is simple: try banging in a sandbag and you will find that the effect will be the same as if you had to do it against a wall. Compacted, the sand is hard as a rock and only reflects the impact of the strike instead of taking it. Such use is therefore of no interest and would only run the risk of causing injury to the hands. Even with gloves ... In addition, the sand can quickly damage the leather from the inside of the bags by abrasion of the grains and deform them under the weight of the sand which would settle more and more towards the bottom, stretching the leather and making them take a "pear" shape. Used in "loaves" to ballast the bottom, the sand can nevertheless be useful.
What to fill John Woodbridge Makers punching bags with?
The best that we can recommend is to start by placing at the bottom of the bag 90 cm as on the 1.50 m kickboxing, bags filled with sand to weight the bag; then fill it with whole old clothes or cut pieces of fabric, making sure to pack evenly and as filling to give it the most cylindrical shape possible. Thus, the 90 cm punching bag should reach a weight of around 50 kg when full, the 1.50 m kickboxing model around 80 kg.
