Go to a local Army Surplus store or find one on line. Buy a heavy duty top-loading canvas duffle bag, not the cheap zipper type($15-$20). Go to your local bulding supply store and buy several 40 lb bags of sand, (around $3.00 / bag). Leave the sand in the paper sacks that it comes in. Line the duffle bag with a Hefty trash bag. Put in as many 40 lb sacks of sand as you want and tie off the grommets on the duffle bag with clothes line. (Roll the extra material down if you need too). You now have a heavy duty bag that will not break from repeated drops to the floor. Remember picking up bag of sand is much harder than picking up a comparably loaded barbell. [/quote]
This is a great idea. It is actually what I’m planning on doing for the most part. The difference is that I’m planning to get the small size sandbags to put into the duffle bag. This way, I can take those small bags and use for a variety of different exercises like farmers walks and one arm presses.
