I would like to know if I can use this to place over carpet in a room that I am making a home gym?

Our 8mm Pre Cut Rubber Rolls can be placed over low pile commercial carpet with ease. If your carpet is a high pile carpet, there may be some separation in the floor, but depending on what you are doing on the floor, it may not be an issue. If the carpet is a light colored carpet, we do recommend placing a plastic sheet between the carpet and rubber to reduce the potential for staining.
