Are these rubber mats anti-slip? Would they be good for floor exercises?

Our 1/2" Premium Mega Mats are very slip-resistant and even more so when wet. These mats are good for floor exercises, but if you are looking for something that is more impact resistant, then we would recommend one of our mats that are good for high-impact workouts. These rubber mats are vulcanized, meaning they are more dense and durable than our standard rubber mats. So they will be harder underfoot. If you are looking for something with a little give, we recommend checking out our high-impact flooring on our High Impact Flooring page.
