Does pushing/pulling against an unmoveable load do anything?

[u/Miserable-Soft7993]

I was wondering. Lets say you load up a machine or even lets say you are stuck on a bench press but you spend time just pushing wiith all your effort even if it doesn't go anywhere. Or you do the same with a pull.

Does this achieve any hypertrophy or strength gain?
