Gravity Fitness's Heavy Duty Sand Bag is the number four entry in this guide. It is a 1000D nylon sandbag with a Velcro filler bag inside, sold for strongman and functional training, priced at £49.95 and rated 4.4 out of 5 from 126 Amazon ratings. The listing names five sizes: 50 kg, 75 kg, 100 kg, 125 kg and 150 kg.

The finding worth stopping on is the gap between two weight numbers on the same page. The size field reads 50 kg. The item weight field reads 500 g. Both belong to the same listing, and they sit 49.5 kg apart. The bullets explain why: the bag does not arrive filled, so 50 kg is the load it is built to hold once you have bought and added your own sand, and 500 g is roughly what the parcel weighs on the doorstep. A reviewer who filled the 50 kg bag reported that it takes 50 kg just right with a kilo or two to spare — the capacity claim holds up, but only after a trip to the builders' merchant. Everything here is taken from the Amazon listing and its customer reviews, not from any test of our own.
