If you are setting your gym up indoors, and you have a floor that you would like to protect, then I would recommend going with Rubber Gym Flooring. Even if your gym equipment has rubber feet and you train with weights in a precise and controlled fashion, there is still the possibility of dropping a weight plate or dumbbell. This could be a disaster on polished wood floors in a rented house!
Another issue that arises when training indoors is noise. Once again rubber tiles are an excellent solution to this problem as they reduce noise if you have barbells or dumbbells on the ground.
Rubber is nearly always the best for a gym floor given that the main purpose is protection of the floor.Density is important for two reasons. Firstly, you need a dense rubber product to protect the floor when gym equipment impacts the floor. You will see the cheap ones have large shredded granule’s. These not only have inferior shock absorption properties, but they also tend to suffer from wear and tear. The granules aren’t bonded well enough.
