Triangle handstand is to practice the sense of balance, so that everyone can better grasp their own balance in the future. Double handstand is more difficult than triangular handstand, because it requires a much higher sense of balance than triangular handstand, which is like standing on two legs is definitely more stable than standing on one leg. When doing handspring, you must not straighten your legs, or you will fall badly. You should bend down and estimate in your mind when your feet will land. Then you can try handstand (handstand requires a lot of arm strength, you can do more push-ups, and you can go to the gym if you have the conditions). You can try to find the feeling many times when you try handspring, and put your center of gravity forward, that is, don't turn over. Modern people, due to desk work, games and mobile phones, plus staying up late, shoulder and neck function is seriously weakened (I generally use the word degradation). Ordinary people definitely don't recommend doing the triangular support handstand of the head and hand (arm). If they want to try, they must strengthen their shoulders and necks before coming. Others can do a triangular handstand, whether they are capable enough or barely supported, and whether there will be problems after practice can't be seen from the surface! At the age of 20 or 30, it's not worth it to have shoulder and neck problems for the rest of your life because of handstand! I'm not alarmist. Of course, I'm not the one who got hurt. Whether I believe it is entirely voluntary or not, I am too lazy to talk about the structure of the cervical vertebra or how fragile this untrained part is. I have a set of exercises to check the health of my head and neck. At present, most people can't pass smoothly. Generally speaking, teenagers under 14 usually like to run and jump, and soon learn to stand on their heads, because they are physically coordinated and courageous. With the growth of age, the limbs may still be very harmonious, but a serious threshold is fear, fear of falling and fear of pain. I practiced a somersault when I was a child, and my fear has not been lifted until today. I always comfort myself that I don't need a somersault.
