At the age of 50, it is not good to learn Sanda or Taekwondo, because people of this age are no longer suitable to engage in these two sports, especially those who have no foundation before, let alone learn, otherwise it will easily cause serious physical injury. These two kinds of sports require great flexibility and coordination of the body, and a 50-year-old person is not suitable for learning because of the deterioration of all aspects of his body. Taekwondo is divided into competitions, that is, physical confrontation As a 50-year-old, you can practice quality instead of competition. Similar to the routines of China and Tai Ji Chuan, if it is a fitness training method, it is not necessary to pursue the amount of exercise, but only the soft and adaptive amount.
