First, your body won't have as much pressure on it. If you're jumping around, your joints are absorbing impact. On hard flooring, your joints are essentially absorbing all of that impact.
Once you place a mat in-between you and that flooring, the mat will now take the brunt of it. Of course, this depends on the thickness of the mat, and the materials itâ€s made up with.
It also serves as protection from your home flooring, if youâ€re using it as a barrier between you and your floors, or heavy exercise equipment and your floors. Finally, it keeps things more hygienic. No one wants to share mats with a bunch of strangers, not knowing when they were last cleaned or what germs the mat is housing.
