An Olympic weight plates rack is a piece of gym equipment designed to organize and store Olympic-sized weight plates. It typically consists of vertical posts or pegs where weight plates can be stacked or slid onto for easy access and storage. These racks come in various sizes and designs, including wall-mounted, freestanding, or incorporated into larger weightlifting stations. They help keep the gym space tidy and make it convenient for users to find and load the weights they need for their workouts.
