Taekwondo not only makes thin people gain muscle, on the contrary, obese people lose fat and return to normal weight. Taekwondo is different from ordinary sports activities. Doing strenuous exercise will consume 600 calories per hour, and it takes 3500 calories to lose a pound. Therefore, if you practice for an hour every day, you will lose a catty in a week.

Therefore, one of the greatest evils for human beings is to damage health.

Taekwondo is different from the weight-bearing exercise that shows strength, and it is not to adjust large and prominent muscles. Instead, it turns weak adipose tissue into muscle and makes the body light and agile.

The gap between blood vessels is opened by developed weight and moving muscles. Because the number of blood vessels remains the same, it is impossible to add new blood vessels between the expanded blood vessels. In this way, through oxygen inhalation and blood flow, the difficulty of excreta generation in human body is eliminated. Therefore, unnecessary large muscle exercise should develop into flexible muscles, so that the body can get more blood and improve maximum endurance and health.
