Ok so i just bought a thai kickboxing bag to train my stand up for like 130$.So now im a lil short on cash and i been wanting 2 buy a heavy bag to help train ground and such,so i bought an unfilled heavybag for only about 35$.So now i gotta fill it up with sand,and my only question is do it just fill it up with some regular sand frum home depot or sumthing or is there a cartin kind i need to get??i know its knind of a stupid question but idk what to do.
