‘负重’ literally means ‘to bear weight’—‘负’ (fù) means ‘to carry on one’s back’ or ‘to bear’, and ‘重’ (zhòng) means ‘heavy’ or ‘weight’. Together, they form a verb describing the physical act of carrying a load, whether by humans or animals. It is commonly used in fitness contexts to refer to weighted training—such as wearing a weighted vest or lifting loaded backpacks during exercise.

Beyond fitness, ‘负重’ appears in military, outdoor, and occupational settings—for example, soldiers marching with gear or delivery workers carrying heavy packages. It implies effort, endurance, and physical strain, and often carries a connotation of resilience or hardship. While it can be used literally (e.g., ‘负重登山’ — mountain climbing with a heavy pack), it’s rarely used metaphorically without modification (unlike ‘负担’, which means ‘burden’ in abstract senses). The word is neutral in register but slightly formal or technical compared to everyday alternatives like ‘背东西’ (to carry things).
