A dumbbell is a piece of equipment used in weight training, and are considered a type of free weight. It is a weight that is usually held in one hand. Hence, dumbbells normally come in pairs.

"Dumbbells" as a word originated in Tudor England— strongmen used hand-held church bells to develop the upper body and arms. These bells range in weight from a few ounces to many pounds. The bells were flourished in various ways. Obviously this would have made racket so the strongmen would take out the clappers (the thing inside the bell which hits the sides of the bell and makes the noise) so they could practice quietly; hence the name "dumb" as in "no sound" and "bell" - dumbell. When strongmen started to make their own equipment they kept the name, even though the shape changed. For the record kettles were also available in various sizes ranging up to those holding several gallons. When filled with varying amounts of sand or water these two could be used for training. Once again when strongmen started making purpose-built equipment, they kept the name.. This article or section does not cite any references or sources. ...

  • Adjustable dumbbells consist of 14 inch (35 centimetre) long steel bars that are one inch (2.5 centimetres) in diameter. They look like miniature barbells. The centre portion is engraved with a crosshatch pattern (knurling) to help users get a good grip. 1–40 kg of cast iron weight disks (plates) are slid onto the outer portions of the dumbbell to obtain the desired total weight. These weights are secured with clips or collars. A "spinlock" dumbbell's outer portions are threaded, and the collars are large nuts that screw on and secure the plates through friction.
  • Fixed-weight dumbbells are weights created in a dumbbell shape. Expensive varieties consist of cast iron coated with rubber for safety. Cheaper versions consist of a rigid plastic shell that is filled with concrete.
