It is said that the name 'Dumbbell' originated in England between 1485 to 1603, when athletes used actual hand-held bells to train and develop muscle mass. In order to reduce the obvious noise factor, the clappers were removed to render the bell 'dumb' (no sound). Since then, the shape and material of this gear has obviously changed. The two most common types of dumbbells today are Adjustable dumbbells: the overall weight can be adjusted by adding or removing plates/discs to/from the handle Fixed-weight dumbbells: one piece, non-adjustable dumbbells of various materials This type of equipment is used to develop, define/refine and strengthen muscles in arms, chest, shoulders and back.
