How To Make A Heavy Punching Bag

By keeping some basic guidelines in mind, you can learn how to make a heavy punching bag. This type of bag is ideal for individuals who are training in boxing, wrestling, or mixed martial arts--however nearly any athlete can benefit from using this type of bag.

1.  Buy a canvas gym bag. This can be found at a variety of sporting goods, and may even be purchased at local army or navy stores. Make sure to buy a bag that is tubular in shape and contains rings and rope fasteners at the open end of the bag.
2. Spray the bag with Scotchgard in order to minimize the amount of visible sweat stains. Pay close attention to the instructions on the can of Scotchgard in order to achieve optimal results.
3. Line the inside of the canvas bag with plastic--this helps to keep the filler in place, and prevents moisture from reaching the filling. A plastic bag this is big enough to fit the inside of the canvas gym bag can be used for this. Carefully fill the outer edge of the inside of the bag with upholstery foam, keeping an opening in the middle of the filling.
4. Fill the remainder of the bag with clean, dry sand. Put as much sand as can comfortably fit into the bag. Carefully seal both the plastic liner and the gym bag ropes.
5. Connect a heavy chain to the metal rings of the gym bag. Hang the canvas gym bag at a height that will be comfortable for you to use.
