Using for a home gym in the carport but would be laying it out with each workout, is this possible? Also, would I need anything to lay under the mat between the slick carport and the rubber mat, so it doesn't slip?

Our 8mm Pre Cut Rubber Rolls can be rolled out and rolled up with ease if using them as a temporary flooring surface. These rolls are pretty heavy, so you won't need to put anything under the rolls to keep them in place. If for some reason the rolls were to move when performing certain lifting moves, we do recommend placing some double-sided tape under the rolls.
