Exertion works well when effort is strenuous, noticeable, or measurable. Use it for exercise, recovery, work, and formal phrases such as the exertion of force or the exertion of authority.
The climb required many exertions usually sounds unnatural when the meaning is general effort. Use great exertion or a lot of exertion instead. Do not use exertion as a verb.
Formed in the 1660s from exert and the noun-forming suffix -ion. Exert comes from Latin exerere or exserere, meaning to thrust out or put forth, built from ex- meaning out and serere meaning to join or arrange. The physical sense of vigorous effort became common later, around the eighteenth century.
