Weight classification is a system used to categorize individuals based on their body weight, often for competitive sports like boxing or wrestling. This classification helps ensure fair competition by matching athletes of similar sizes, which can enhance safety and performance. In many sports, weight classes are defined by specific weight ranges. For example, in boxing, fighters may be grouped into classes such as lightweight or heavyweight. This system allows athletes to compete against others with comparable physical attributes, promoting a level playing field and encouraging participation across different body types.
