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. The forerunner of the dumbbell was used in India for more than a millennium, shaped like a Club - so named Indian Club .

It was generally used in pairs, in workouts by Wrestlers , bodybuilders, sports players, and others wishing to increase strength and muscle size. "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 a 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..

The word "dumbbell" is used in the United Kingdom as an insulting term for a person considered to be stupid or unintelligent. SEE ALSO |
