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.

  1. 1

    Look for empty items such as soup cans, coffee cans, buckets or paint cans to use as moulds for your dumbbells. Wash them and keep them in a dry place until you have all you need for your dumbbell set.

  2. 2

    Line up the moulds and use the amounts they held to estimate how much concrete mix you will need. A 454gr coffee can will hold about 2 cups of concrete.

  3. 3

    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.

  4. 4

    Spray the insides of the moulds with silicone lubricant.

  5. 5

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

  6. 6

    Wait for 24 hours to make the other end. Fill the moulds 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.

  7. 7

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

  8. 8

    Remove the moulds once the concrete is dry.

Tips and warnings

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