Upper back strengthening hinders performance?

Hi,
This year I’m planning to do some strength workout, espacially on my upper back which is weak due to the entirety of my time spent either on the bike or sitting at the computer. It lead to a bad posture and I don’t like it.

So I’m wondering if bringing your shoulders back through upper back strengthening and chest stretching would affect performance in some way ( maybe it brings a less aero position, especially on a tt bike ) ?

Ps : I’m not a pro athlete so if I have to choose between posture and performance, I’ll always choose posture.
I’m just curious if any research has been done on this !
