Describe a situation where you have applied a lot of force (and maybe even felt tired afterward) but did no work in the sense we study it in Science class.

A situation where I have applied a lot of force but did no work in the sense we study it in Science class would be pushing against a wall. Even though I am applying a lot of force, I am not doing any work because the wall is not moving. I may feel tired afterward due to the effort I put in, but no work has been done.
