My friend has a punching bag I use all the time before we spar. I believe its 75lbs and it gets the job done fine, though I wish it were a little heavier. I'd recommend wearing some kind of hand protection while doing this, you don't wanna tear your hands up. And don't do something stupid like hold your thumb in your hand while you punch, it'll just break your thumb.
