I am looking for a flooring I can install over carpet for a home gym. I had used horse stall mats before but it left marks on the carpet and had a strong plastic smell.

Our Rubber Gym tiles can be used over low to medium pile carpets, but high pile carpets can cause the tiles to separate. Light colored carpets do have the potential to be stained by our tiles due to them being black on the bottom. An easy solution to prevent staining is to place a thin plastic sheet underneath your tiles. Our rubber gym tiles do have a slight rubber smell to them, but this smell will dissipate over time.
