The Economy Series Bumper Plates are sized to international Weightlifting Federation (IWF) standards and come as a full set of 230 LB in pairs of 10, 25, 35, and 45 LB. Crafted with durable steel cores enclosed in a stylish black gloss rubber coating, they’re made to withstand vigorous workouts and maintain their shape over time. These Olympic weight plates fit all standard 2" barbells and look great in any home gym. Plus, the raised edges make them easy to handle when adjusting your weights on your barbell and allow for a wide variety of additional free plate exercises, including weighted sit-ups, bent-over rows, squats, lunges, and presses.
