If you are like a lot of people, finding dumbbells for your home gym can be difficult and expensive. If you are looking for a cost-effective solution, you might want to try the Rock Weights 80-pound Dumbbell Molds. You can make your own 40-pound or 80-pound dumbbells at home when you purchase concrete separately at a local hardware store.
The molds are made with a crack-resistant material so you shouldn’t have to worry about longevity. The 40-pound dumbbells come with a down handle for extra durability but given the thickness of the handle and sidebars on the 80-pound molds, they do not require a rebar. Reviewers seemingly love these molds and claim they are a cost-effective solution to their heavier dumbbell needs.
