My first response to this? Where can I get it? For slobs who like to pile on laundry like nobody's business or for the person that likes to change every 3 hours, this laundry bag will double up as a punching bag.

It can be hung in the closet, which keeps the laundry bag off the ground while you pack it on for a good workout. The more clothing you have it in, the more it will resist your blows.  [Suck UK via Fancy]
