Step 1

Remove any hooks or straps from the punching bag with scissors.

Step 2

Open one end of the punching bag to expose the inside stuffing material.

Step 3

Fill the punching bag with 1-inch closed-cell foam and pack tightly. The closed-cell foam keeps its shape and provides the most amount of weight.

Step 4

Weigh the punching bag. Remove or add closed-cell foam until you reach the desired weight.

Step 5

Close the punching bag by sewing the two layers or duct-taping them together. The duct tape will help to extend the lifespan of the heavy bag. If possible, reuse the original hooks and straps.

Step 6

Test the heavier punching bag with a variety of punches and kicks. Note the overall feel of every strike and make any necessary adjustments to the foam.
