How to Make Dumbbells With Concrete


Making your own dumbbells at home may not save you a fortune, but it will enable you to tailor your equipment to meet your individual needs. It is also a fun project that you can do with your family. Using easily obtained, common items and a little work, you can make dumbbells that weigh as little as a few ounces to a couple of hundred pounds.

Things You'll Need

  • Empty containers or molds
  • Fast-setting concrete mix
  • Metal rods or dowels
  • Wheelbarrow or bucket
  • Water
  • Silicone lubricant
  • Spade
  • Look for empty items such as soup cans, coffee cans, buckets or paint cans to use as molds for your dumbbells. Wash them and keep them in a dry place until you have all you need for your dumbbell set.

  • Line up the molds and use the amounts they held to estimate how much concrete mix you will need. A 16 oz coffee can will hold about 2 cups of concrete.

  • Mix the concrete according to the directions on the package. Every brand is different, but most quick-setting concrete involves mixing the powder with enough water to give it a batter-like consistency.

  • Spray the insides of the molds with silicone lubricant.

  • Use a spade and fill the molds you are going use for one end of the dumbbells and quickly place the metal dowels in the center of the concrete. Make sure the dowels reach the bottom of the container.

  • Wait for 24 hours to make the other end. Fill the molds for the other end of the dumbbells and leave the concrete to start to set. This will be anywhere from a few minutes to an hour.

  • Take the one-ended dumbbells, turn them upside down and place the metal dowels in the center of the second batch of dumbbell molds. Set the dumbbells against a wall or some place hard and flat where they will not be disturbed for 24 hours.

  • Remove the molds once the concrete is dry.

Tips & Warnings

  • Paint the dumbbells different colors to suit the personality of the person using them.
  • Never begin weight training of any sort without a full checkup by your doctor.
