How useful can it be to practice fist hardness and strength in actual combat?

I practice iron fist. I want to make a long story short and help you:

1: If the fist is hard enough, it is very useful in street fighting. For example, if you hit each other's bones, you won't feel pain. Strength is about explosiveness, not brute force. Only explosive power can hurt people. If the two are combined, at least others can hardly afford to fight you.

Push-ups are only auxiliary exercises, and it is best to do them with fists on the concrete floor. When you practice to a certain extent, you can try to hit the ground with your fist and practice heavy sandbags, at least 200 kilograms. Melaleuca paper is a traditional practice method, and the purpose of practicing heavy sandbags is the same, but Melaleuca paper is different from sandbags. The sandbags will move when you hit them, but there is a wall behind Melaleuca paper. How much reaction will your wrist bear when you hit them, unless you hit them. Sit-ups are the strength to practice waist and abdomen, and boxing and waist strength are also very important.

3. The fist must be in place first. First, practice your movements and pay more attention to boxing. Have you seen the iron fist in Kung Fu? Wear several iron rings on each hand. You can choose a sandbag for tying your hands, which weighs about two kilograms. Practice punching with the fastest speed, then take down the sandbag and experience the feeling of punching. And target practice. Ask a friend to help you.

4. inch boxing requires short-distance explosive power, and the faster the speed, the stronger the explosive power. Power varies from person to person.
