Therefore, they are suitable for Olympic weightlifting, which often involves dropping plates to the floor, such as snatch, clean \u0026amp; jerk, and hang clean.\u003cbr\u003eIron plates, on the other hand, are suitable for exercises where weights are not dropped to the floor, such as bench press, squats, and curls. Dropping iron plates can damage the floor, barbell, or the plates themselves.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs there anything I need to do when my bumper plates arrive?\u003c\/strong\u003e\u003cbr\u003eOnce your bumper plates arrive, remove them from their packaging and air them out in a well-ventilated area for a few days. This can help reduce any faint residual odors specific to the product.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow can I make my bumper plates last longer?\u003c\/strong\u003e\u003cbr\u003eTry to drop the plates as directly downwards as possible. If the barbell collars loosen during training, retighten them to ensure the plates always land vertically. This can reduce the lateral force on the center disc of the bumper plates.\u003cbr\u003eAdditionally, using flooring that can absorb some impact, such as thick rubber mats or weightlifting platforms, can reduce the shock when plates are dropped.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I mix bumper plates and iron plates on the same barbell?\u003c\/strong\u003e\u003cbr\u003eGenerally, it is not recommended to mix bumper plates and iron plates on the same barbell. The diameter of iron plates and bumper plates may differ slightly. If the barbell is dropped in such a state, the impact will concentrate on the plate with the larger diameter, potentially accelerating wear and tear on that plate and the barbell.\u003cbr\u003eHowever, combining full-sized bumper plates with change plates is acceptable as long as the total weight of the smaller diameter plates does not exceed 10kg. If it reaches 10kg, it is recommended to remove the change plates and replace them with 10kg bumper plates of the same diameter.\u003cbr\u003eExample:\u003cbr\u003eIf you load a 20kg bumper plate, a 5kg plate, and a 2.5kg plate on each side of the barbell, the total weight will be 75kg, and this combination is fine. If you want to increase to 80kg, instead of adding smaller plates, remove all change plates and replace them with 10kg bumper plates.\u003cbr\u003eTo ensure your plates and barbell last as long as possible, we recommend using the same type of plates whenever feasible.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the diameter of the center hole? And what size barbells are they compatible with?\u003c\/strong\u003e\u003cbr\u003eAll REP bumper plates have a 50mm Olympic standard center hole and are compatible with 50mm Olympic barbells.\u003c\/p\u003e","brand":"REP Fitness","offers":[{"title":"10kg pair","offer_id":49729677951204,"sku":"BP-6500-10-1","price":27900.0,"currency_code":"JPY","in_stock":false},{"title":"15kg pair","offer_id":49729677983972,"sku":"BP-6500-15","price":33900.0,"currency_code":"JPY","in_stock":false},{"title":"20kg pair","offer_id":49729678016740,"sku":"BP-6500-20","price":39900.0,"currency_code":"JPY","in_stock":false},{"title":"25kg Pair","offer_id":49729678049508,"sku":"BP-6500-25","price":49900.0,"currency_code":"JPY","in_stock":false},{"title":"90kg set","offer_id":49729678082276,"sku":"BP-6500-90","price":100900.0,"currency_code":"JPY","in_stock":false},{"title":"110kg set","offer_id":49729678115044,"sku":"BP-6500-110","price":117900.0,"currency_code":"JPY","in_stock":false},{"title":"120kg set","offer_id":49729678147812,"sku":"BP-6500-120","price":123900.0,"currency_code":"JPY","in_stock":false},{"title":"140kg set","offer_id":49729678180580,"sku":"BP-6500-140","price":150900.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0648\/0376\/6500\/files\/BP-6500-20.jpg?v=1787839916","url":"https:\/\/uchinogym.com\/en\/products\/black-competition-bumper-plates-kg","provider":"ウチノジム","version":"1.0","type":"link"}
