Exercise mats provide extra comfort and support during floor workouts. These floor mats are often called yoga mats, but are entirely suitable as pilates mats and for doing other exercises, such as crunches or sit-ups. It's up to the individual to decide whether or not they prefer a thick fitness mat or a thin mat, but every exercise mat should be feature a friction-free surface to provide the least amount of slippage upon both hardwood and carpeted floors. Some mats come with their own carrying case for easy transport to the studio, spa or gym. They are flexible and can be tightly rolled for placement in a duffel or suitcase while traveling.
