A stone mat feels great on the feet; it feels natural, so enjoy it and be careful not to overdo it.
To begin practicing crulsing with a stone mat, place the mat on the floor near a wall, bed, or chair for stability. You can stand or sit using the stone mat to perform various forms of exploration, such as massage, stretching, or resistance.
Choose the form of exploration that works best for you, and be mindful not to overdo it, as the stone mat can feel great on the feet and feel natural.
Enjoy the experience, and be careful as you practice.
