Unfortunately, she slid around on my first wooden floorboards, so that for example was etc. not to think of aerobics. After the inferiority of a non-slip mat has the true set, but at floor exercises (eg push ups) I slip on the mat getting away, no matter if I barefoot, with socks or sneakers slip (have tried several) use. That's annoying.
However, since the mat is good for Step and Sit ups etc. is soft, I give the product three stars. I would not buy me the mat again; Send back was due to the size of the mat but also not an option. The mat was like a piece of furniture by a forwarding agent, so I had to be home within a time window and wait for the delivery.
