Okay, a while ago I used a large freestanding bag in my condo filled with water. I found that when I hit it, even slightly it slid on my carpet very easily. This is annoying. I do not have a room in my house that is non-carpeted that is large enough to practice in. I would like to get another one, but I was wondering if anyone else has ran into this problem and what you have done to minimize the sliding on carpet.
