I have wanted to do some sandbag training for a while now. My goal was to use things around the house in order to make these completely free. Lest I get some complaints, I know it's not best sandbag option out there. I'm not saying it's good for any purpose you might want to use a sandbag. I'm just showing you what I did to make some basic heavy bags for free. These weigh 50 lbs. each. I've had them for a month now and they have been working well for my purposes so far.
