Why Use Bumper Plates?
Bumper plates would not be in existence if not for the sport of Olympic Weightlifting. Olympic Weightlifting was included in the Olympic games as early as the 1890's. The first games featured one hand and odd lifts as well as the traditional Snatch and Clean and Jerk. Original weightlifting plates were made of steel and cast iron. As records increased it became necessary for weightlifters to drop the weights from overhead rather than risk injury to bring them down after the extreme physical exertion from the execution of the one rep maximum lift. First attempts at manufacturing rubber bumper plates resulted in very thick rubber plates that caused issue when trying to add multiple plates to the weight bar. Making the shaft of the bar longer to accommodate the thickness of the plates was not an option as it displaced the load further from the lifter's body, making the lift harder than it inherently is. Later on, Vulcanized rubber was used to create bumper plates. The process of vulcanization makes a harder, thinner, denser plate that is more durable than recycled rubber bumper plates.
Bumper Plates allow the lifter to safely drop heavy weights from over head which is an essential aspect of the Olympic Weightlifting movements. Bumper Plates also allow the lifter to safely miss lifts when beginning to learn technique based weightlifting or attempting maximal weight squats and or heavy overhead lifts.
Vulcan Bumper Plates are recommended for commercial gym use, high school and college weight rooms, CrossFit gyms, athletic training centers, home gyms, and police, military or first responder training environments.
Our black bumper plates are safe for dropping on wood platforms or athletic rubber flooring. They are not recommended for dropping on concrete or aggregate surfaces. Please see our Alpha Bumper Plates for outdoor use bumper plates.
