tighten up
Reduce the slack
Tighten up means to make something more secure, efficient, or disciplined.
You tighten up a loose bolt, tighten up security after a breach, or tighten up a sloppy first draft.
A coach tells players to tighten up their defense.
The phrase emphasizes the process of improvement—making something firmer, stricter, or more controlled than before.
