This mainly depends on what exercise you do. Yoga mat is the most commonly used mat for fitness. Besides practicing yoga, Pilates, for example, is also a yoga mat, which is also very convenient to carry. If it is a high jump, the protective mat for the long jump is thick and heavy. In addition, there is a meditation situation, where there is a special meditation mat, such as practicing a single dish, and something must protrude under the ass, which is in line with the human skeleton structure and human mechanics principles. Otherwise, meditation only uses yoga mats, which will affect the spine for a long time.

Well, I hope the above suggestions can help you, and you'd better find a professional fitness person to give you guidance.
