I just bought a 100 lb. Everlast punching bag, but when I kick this thing, it fricken hurts. The bag is too hard. I don't know what they put in it, but it hurts to kick it. My TKO brand bag had strips of cloth and foam in it and it was soft, even in the areas where it's really compacted. Anyone else have this problem? Or does anyone have a way to make it softer? Thanks.
