常人提到铁砂掌，想到的都是很神秘的技法，可能和熊拍击树干时候一样威猛，其实不然，在真正的传统武术习练者中，铁砂掌就是很普通的一种基本功训练。铁砂掌在以前只是武师为了增加手掌手指的劲力，发明的一种习练方式。

When people mention the Iron Sand Palm, they often think of a mysterious technique that might be as powerful as a bear striking a tree trunk. However, in the realm of true traditional martial arts practitioners, the Iron Sand Palm is actually a very ordinary basic training method. In the past, the Iron Sand Palm was merely an exercise invented by martial artists to increase the strength of their palms and fingers.

今天的铁砂掌分为内练和外练两种，内练的铁砂掌是先辈传下来的，外练的铁砂掌也称为速成铁砂掌，是因为之前的武林先辈不得已而告知世人临时增加手掌强度的方法。

Today, the Iron Sand Palm is divided into two types: internal practice and external practice. The internal practice of the Iron Sand Palm is passed down from predecessors, while the external practice, also known as the quick-learn Iron Sand Palm, was revealed to the world by martial arts predecessors as a temporary method to enhance the strength of the palms.

掌功训练的目的是为了让手掌更灵活，更健康，更强壮，也并非用手掌去劈山裂地。传统的铁砂掌练习确实也是通过拍击来强大手掌，但是并不会变形。

The purpose of palm training is to make the hands more flexible, healthier, and stronger, not to use them to split mountains and crack the earth. Traditional Iron Sand Palm exercises do involve strengthening the palms through striking, but they do not lead to deformities.
