broke one's back

Strained beyond limits

To break one's back is to work extremely hard, typically at physical labor, often with the implication of exhausting or injurious effort.

I broke my back getting this place ready for the party.

The expression emphasizes grueling exertion rather than literal injury, though it evokes the physical toll of demanding work.

Someone who breaks their back for something or someone sacrifices their comfort and energy for that cause or person.
