I am really getting into fine tuning my bench form. One of the things I notice is that the vinyl covering on my bench is kind of "slippery." I am a firm believer in staying tight on the bench, and I think a rubber pad of some sort would help my upper back "lock on" to the bench and allow me to maintain my arch and stay tighter. What would you recommend? Thanks. Aren't some of the Forza and other high end benches coming with special grippers for this?
