So, here's the deal, my elbows have been taking a beating from deadlifting. I don't drop the bar, but when progressing on the lift, there is impact. I ordered stall mats from Amazon, they sent me the wrong ones. I ordered stall mats from overstock and they canceled my order and said they were out of stock. Every site I go to to order stall mats wants over $200 in shipping! So I got to thinking, Amazon had bumper plates. I can onyl afford to buy two 45 pound bumper plates and then use my steel plates with them when I deadlift. I deadlift on carpet. Would the plates help similar to have a rubber mat would and would the plates hold up at least for awhile(lets say a year when deadlifting once a week)?
