How to make cheap dumbbells

The theme of cheap dumbbells is quite relevant. Indeed, in the store, every kilogram of this shell is estimated at the fabulous amount.

I once read Xrust that the athlete, who lived before the revolution, began to train with a bag full of sawdust. As the training, he took a handful of sawdust from the bag, and replaced a handful of sand.

When the restructuring came, bottled water appeared. Emerged bottles — threw it away. Then from the lack of money appeared among young people a fashion for dumbbells from these bottles. They poured sand in them, adjusting weight. They started, of course, with water.
