I've had a slip bag for a while so I could practice head movement at home. I hang it in my door way but theres not an adequate amount of space- keep in mind I'm standing either outside the door way or in the room lol I am not in the middle of the doorway. Walls get in the way, I'd hate to waste it does anyone have any advice on hanging it? It a nine pound everlast slip bag on a chain not a home made one Thanks!
