How to do hand exercises to exercise the heart?

Because the nerve in the hand and the cranial nerve are connected in the bone marrow, there will be some heart causes that cause finger and arm pain.

The following is a complete method of hand exercise:

1. "Inside", palms open, palms down, thumbs flat;

3. "Root", two palms are opposite;

4. "Sharp", hands spread out into a ball, and ten fingertips hit each other;

5. "fork", with two hands and four fingers spread out and fingers crossed;

6. "fork", with both hands and thumbs spread out, the tiger's mouth crosses and hits;

7. "Heart", right hand clenched fist, flat hit left hand heart;
