Dumbbells: Types and History

The Dumbbell, also known as hand weights and free weights, is undeniably one of the most common equipment utilized for weight training. It is usually used in pairs but can also be used individually. It consists of a narrow single bar in the middle with equal weights on each end. Some dumbbells are very light in weight while others are very heavy. With this, dumbbells vary from only a few pounds to as heavy as 50 pounds or more. In addition to that, they can be fixed in weight or variable. Weight discs can be added or removed from the bar by quantity or by size. Most people think that this type of equipment has only been in the modern ages. However, this versatile piece of free weight tool has been used for a variety of exercises since 2,000 years ago.

As stated above, the dumbbell has been used for weight training in order to tone and increase the muscle size. They are frequently used by bodybuilders, powerlifters, athletes, and other exercise enthusiasts within their workout routines. Each exercise designed using the dumbbell targets a specific group of muscles. With comprehensive and regular exercise, muscles of the arms, shoulders, back, chest, legs, and core can be developed in order to be more toned and strong.

History of Dumbbells

The history of dumbbells traces back to the ancient Greek times around the 5th century B.C. They used the word “Halteres” which means to lift weights or heavy material. Historians and Archaeologists have found out that Greeks used handheld weighted objects similar to the modern dumbbells to strengthen their muscles. In India, a club-shaped device called “Nal” was used for almost a millennium for the same purpose of lifting weights. However, this version of India can be considered as a midpoint between a barbell and a dumbbell. Over many centuries later, plummets and lead plus with wood were used just like the dumbbells modern times have. Early Physicians have observed that these heavy metal plates can be used for exercise in order to improve the lifestyle and overall health of people.

After the modern eighth century, the term “dumbbell” was established from England. However, its meaning is not the same with the modern definition of dumbbell. During that time, it means the practice of pulling the rope for the ringing of heavy church bells high in church steeples. It means the practice of bellringing. In order to do bellringing, it took much strength and practice to ring heavy church bells, so inexperienced bellringers were taught without the use of the clappers within the bells. The noiseless ringing of bells caused for the english people to associate the word “dumb”. After such time, the practice of bellringing came to be known as a “dumbbell.”

Around the Sixteenth century, people of England realized that they could improve their physique by working with these dumbbells attached to ropes. After such time, in the Nineteenth century, the original rope and weighted bell-like object was developed and replaced with a short bar and rounded discs with weights on each end. This evolved to be known as the modern dumbbell people use today.
