Bought the mat to cover my floor, as it is too slippy to exercise on it n also to protect the floor if I drop a weight or smth. Well it works well as long as no jumping is involved. As soon as i try to do skipping or jumping aerobic exercises or just steps to the side a little faster, it starts moving with me, not safe at all! Also mats start coming apart. They never dislock, but there is a gap between the mats.
They are not non slippy at all either. If I do any more advanced stretch, my feet slowly start slipping away unless i take even my socks off. This way I can stay in the stretch a few seconds longer without my feet slippin away.
So overall I am very disappointed with the product, especially as paid so much for it, got 2 sets of it so that I can cover the area i need. Would definitely not recommend it for gym use or for exercising. :(
Probably useful to put it under furniture to protect floor and might be good for exercise as long as it goes from wall to wall, as then it cant really move unless it would crush up which i dont think it would, but it will still be slippy, though...
