The floor of the gym is covered with spliced rubber mats, which is more troublesome. You can buy a whole IKU fitness mat. It's an oversized mat, which can be spread out directly when used and rolled up directly when not in use. There are many sizes, and the largest size is 300cm* 180cm. Of course, the size should be selected according to the size of the site, and the measurement should be in place at one time.
