Morphology
break + the + back + of
The phrase uses a structural/metaphorical sense of "back" (the main support or hardest part) and "break" (to overcome or destroy), so there is a detectable link to the idea of getting past the hardest part of a task. However, that metaphorical mapping from literally breaking a physical "back" to completing the most difficult part is idiomatic and not fully predictable, so a B1 learner who only knows the words would likely only partially infer the intended meaning without prior exposure.
Etymology
The idiom break the back of may come from the image of break and back: imagine snapping the main support or spine of a big object so the rest gives way. So it means 'to complete the most difficult or important part of a task, making the rest much easier'.
