I just got a heavy bag for XMas, and today my roommate and I set it up. It slipped my mind that the room we were gonna put it in was a finished garage and thus has a much higher ceiling than a normal room would. At the moment, the bag is 46" off the ground. It's too high up to throw body shots and it swings around like crazy since you're just hitting the bottom of the bag. Obviously I'm gonna buy a longer chain for it, but I was wondering if anyone knew a specific distance it should be from the ground?
