Fitness is not like Sanda. More people only consider their body shape and health. Of course, fighting is not ruled out. At least those who persist will be better at endurance and agility than those who lack exercise. Getting used to fitness is good for you, and the continuous output of body, spirit and energy will be better. People who have the ability to exercise usually have considerable self-discipline in their lives. It's hard to say that fighting is not bad. At least, if you do it often, your physical strength will not be bad.
