ELI5: When you push an object (but don't push hard enough to move it!) you use up energy but don't get any work done. Where does this energy go?

Imagine you push against a wall. You won't move it because it's too heavy and fixed in its position. But since you continuously apply a force to it there needs to be some sort of energy transfer. Does the wall take up that energy?

There is no **mechanical** energy gained/transferred. All the energy is "lost" within your body and mostly turned into heat etc.

Otherwise this is essentially the same thing as an object being rested against the wall or just standing on the floor. There is a force but no transfer of energy.
