up one's game

Raise your standard

To up one's game is to improve one's performance or raise one's standards, typically in response to competition or challenge: She really upped her game after the promotion.

The expression comes from sports but applies broadly—work, relationships, creative pursuits.

The possessive shifts with the subject: up your game, up their game.
