Let's say a sports team puts in a lot of effort and as a result perform very well. You could say they have "-blank-ed themselves" as praise. I feel like the word is on the tip of my tongue but I can't think of it.
Someone who does exceptionally well, particularly compared to their past performance can be said to have "outdone themselves"
We knew the importance and significance of this tournament, and credit must go to each and every individual. And also to all the management and backroom staff. They've all outdone themselves."
They have excelled (themselves):
: to be superior to : surpass in accomplishment or achievement
