Katherine Hunt at Cabinet Magazine:
In an article in the Spectator in July 1711, the eponymous character Mr. Spectator—as written by Joseph Addison, one of the magazine’s founders—described his exercise routine. When in town, and therefore not able to go out riding, “I exercise myself an Hour every Morning upon a dumb Bell that is placed in a Corner of my Room, and pleases me the more because it does every thing I require of it in the most profound Silence.”1 We know dumbbells now as handy at-home pieces of gym equipment—free weights that have been around, in some form, at least since ancient Greek athletes used halteres to increase the length of their long jumps. But the dumbbell that Mr. Spectator refers to, and from which the heavy gym weights borrow their name, is something different. An illustration of a similar piece of equipment, published in the Gentleman’s Magazine in 1746, shows a wooden contraption in which two crossed bars with weights on the ends are mounted on an axle, around which is wound a length of rope. This mechanism would be elevated within a room, or placed in a garret, with the rope hanging down for a person standing below to pull. It mimics the apparatus used for ringing church bells, with the bell itself replaced by two weighted bars—it’s these that resemble the dumbbells of today.
