The iron sand palm hurts the body, purely for hitting people. At least I haven't heard of the secret door of fitness. The landlord should practice killing and keeping in good health, not keeping in good health. I recommend Xingyiquan. After all, he has a saying that he will not go out for ten years and kill people for one year. And there is physical exercise. The combination of playing and practicing is the most scientific.

Iron sand palm should be medicated with wine, which will hurt the kidney. It's not cost-effective to practice martial arts and hurt the kidney. The image behind you is great.

Or you can use other methods to integrate your own style of play and use others to strengthen yourself.

If you really love iron sand palm, it is recommended to practice only. If you practice, your body will be really hurt. Meaning practice refers to achieving the purpose of your own practice through the concept of yoga.

It is also the key to practice boxing quickly or even slowly.

Half send half don't send, mount tai in my arms. Push slowly for a long time, and the palm strength will increase. This is a good way to practice palm strength.

I hope it helps you.
