"Gotten a workout" is a colloquial expression used informally to refer to a person or an object having undergone physical exertion or being heavily used. It implies that something or someone has been subjected to intense or rigorous activity, resulting in strains, fatigue, or substantial use.
The phrase primarily stems from American English, where "gotten" functions as the past participle of "get." While the word "workout" encompasses numerous activities related to physical exercise, such as strength training, aerobics, or various sport activities, in this particular context, "gotten a workout" is commonly used metaphorically to indicate thorough usage or exertion outside of the realm of typical physical exercise.
For example, if someone says, "My brain has gotten a workout today," they mean that their mental faculties have been heavily taxed or challenged. Similarly, if someone comments that their car has "gotten a workout" after a long road trip, it signifies that the vehicle has endured an extensive period of driving, putting strain on its mechanical components.
In conclusion, "gotten a workout" is an idiomatic expression used to convey the idea that something or someone has experienced an intense or exhaustive period of activity, beyond the literal sense of physical exercise.
