Exert is a keyword action introduced in Amonkhet.[1]
Description
When a creature with the exert ability is declared as an attacker, its controller decides whether to exert his or her creature. If he or she does, then an ability is triggered and the creature doesn't untap at the beginning of the next untap step.
The flavor of this mechanic is as follows: if the creature exerts, it means the creature is expending a large amount of effort, resulting in a bonus. As a result, the creature is then exhausted by the effort, and thus it doesn't untap in the next untap step.
