For other uses, see Dumbbell (disambiguation).

Not to be confused with barbells, a larger version of the same concept, held with both hands.

A pair of adjustable dumbbells with 2 kg plates.

The dumbbell, a type of free weight, is a piece of equipment used in weight training. It can be used individually or in pairs, with one in each hand.

History

Young boy holding a discus at the palaestra. Near him, a pick to prepare the landing ground for the long jump and a pair of dumbbells (halteres) used to maintain equilibrium during the jump. Interior of an Ancient Greek Attic red-figure kylix, 510–500 BC, Louvre Museum, Paris.

Dumbbells (halteres) used in athletic games in ancient Greece, National Archaeological Museum, Athens.

The forerunner of the dumbbell, halteres, were used in ancient Greece as lifting weights and also as weights in the ancient Greek version of the long jump. A kind of dumbbell was also used in India for more than a millennium, shaped like a club – so it was named Indian club. Despite their common English name implying an Indian origin, the so-called Indian clubs were in fact created in the Near East. Properly referred to as meels, they are first recorded as being used by wrestlers in ancient Persia, Egypt and the Middle East. The practice has continued to the present day, notably in the Varzesh-e Bastan tradition practiced in the zurkaneh of Iran. From Persia, the Mughals brought the meels to South Asia where are still used by pehlwan (wrestlers). British colonists first came across Persian meels in India, and erroneously referred to them as "Indian clubs" despite their Middle Eastern origin. The design of the "Nal", as the equipment was referred to, can be seen as a halfway point between a barbell and a dumbbell. It was generally used in pairs, in workouts by wrestlers, bodybuilders, sports players, and others wishing to increase strength and muscle size.

Etymology

"Dumbbells" as a word originated in late Stuart England. It referred to equipment used to simulate the action of pulling a bell rope. Designed to develop technique, and especially strength, to practise English bellringing (see Change Ringing), dumbbells made no noise, and were hence "dumb". When strongmen started to make their own equipment, they kept the name, even though the shape and form changed. See Oxford dictionary definition.

Types

By the early 17th century, the familiar shape of the dumbbell, with two equal weights attached to a handle, had appeared. There are currently three main types of dumbbell:

A spinlock adjustable dumbbell.

• Adjustable dumbbells consist of a metal bar whose centre portion is often engraved with a crosshatch pattern (knurling) to improve grip. Weight disks (plates) are slid onto the outer portions of the dumbbell and secured with clips or collars. Shown to the right is a "spinlock" dumbbell, whose ends are threaded to accept large nuts as collars. Alternatively, a dumbbell may have smooth ends with plates being secured by a sprung collar. Nowadays, many commercially sold dumbbells are available with sophisticated, and easy-to-use methods for weight increments adjustments.
• Fixed-weight dumbbells are weights created in a dumbbell shape. Inexpensive varieties consist of cast iron, sometimes coated with rubber or neoprene for comfort, and even cheaper versions consist of a rigid plastic shell that is filled with concrete.
• "Selectorized" dumbbells are adjustable dumbbells whose number of plates (i.e. weight) can be easily changed when resting in the dumbbell stand. This is achieved by adjusting the number of plates that follow the handle when lifted, e.g. by turning a dial or moving a selector pin — rather than manually adding or removing plates. This makes it very easy to change the weight of the dumbbell between exercises, and the stand typically doubles as storage for the additional weights not being used for a particular exercise.
