It may be because the back is stretched to get tired.

It is said that tiredness is difficult to get out when the back is tight.

People of the type with their back stretched
My breathing is shallow.
Those who are stiff around the diaphragm on the opposite side of the back,
Arms, chest and armpits are also stretched.

When the back is tight,
Turn on oil and back. Chest, arms and palm
slowly, slowly
You will stretch your fascial wrinkle to iron it.

Then, breathing becomes easier, and the body refreshes.

Even one person can do it.
After warming your body with a bathtub in a bathtub,
Use gentle stroking with a body soap to take wrinkles in the cori
Please heal.

And while stroking,
You also worked hard today.
Thank you.
Talking to him,
Moreover, the body is pleased.
