n. physical or mental activity to improve health or skill
vt. to engage in physical activity for health or training
vt. to use or apply (a right, ability, or quality)
Derived from Latin exercitium (training, practice), from exercere (to train, keep busy), combining ex- (out) + arcere (to restrain, enclose). The original sense implied "driving out" lethargy through disciplined activity. Over time, it broadened to include both physical and mental exertion. The suffix -ise marks it as a verb in English.
