I purchased this mat for working out on instead of using it underneath exercise equipment, which is it's stated purpose. It is larger than many workout mats, which is great for P90X exercises where you often are jumping around and doing different exercise moves on the floor. I needed an exercise mat because my entire apartment is ceramic tile, and many exercises (mainly pylometrics) are terrible on your joints while on a hard floor. This mat provides adequate thickness for use on a hard floor, it's not too soft nor too hard. It does slip on the floor a bit, but overall its great for working out on.
