This classic piece of weight training equipment is essential to the world of fitness and especially that of weight training and free weight exercises. This piece of equipment consists of a short bar with a weight at the end of the small bar; they can be used on their own or in pairs depending on the exercise.
As Defined in the Oxford English Dictionary
“a short bar with a weight at each end, used for exercise or muscle-building”
So now we have a good idea of what it is, but why is it called a dumbbell?
To avoid making undue noise while training, the bell was removed, making it ‘dumb’. The dumbbell itself is an apparent evolution of Halteres, a weight used in ancient Greece, often used in pairs.
The modern dumbbell you see today has been developed to be more functional and ergonomic. As a weight training tool with two heavyweights on either end of a bar which made no noise, the name ‘dumbbell’ stuck and it’s now synonymous with the training tool.
