Etymology

Origin of exercise

First recorded in 1300–50; Middle English (noun), from Middle French exercice, from Latin exercitium, from exercit(us) “trained” (past participle of exercēre “to train,” from ex- ex- 1 + -ercēre, combining form of arcēre “to restrain”) + -ium, noun suffix

Explanation

Exercise is physical activity, like an exercise class, or the act of practicing anything — like people who exercise caution while crossing the street. If your dad tells you to exercise restraint in dealing with your brother who just broke your computer, he hasn't suggested that you tie your brother up — here exercise means "use" or "practice." This might remind you of the writing exercises your teacher gave you: practice in forming letters. In many kinds of exercise, the results come from doing something over and over — just ask anyone who exercises, or works out.
