The story behind this Chinese proverb:

In the Eastern Han Dynasty, there was a man named Ma Yuan. He had been planning to herd animals on the frontier since he was young. When he grew up, Ma became a minor official of a county.

Once, he was sending some prisoners to another location. He felt pity for them, so he set them free, and then he fled to another county in the north. He herded animals there, and thus his dream came true. He always said: “If you want to be a great man, the poorer you are, the firmer in spirit you have to be; the older you are, the more spirited you should be.”

Later, when he was even older, Ma Yuan became a famous general of the Eastern Han Dynasty and contributed to many battles.

表壯不如里壯 literally translates as: [Better to be] strong inside than [to be] strong outside.

The ancient original meaning was:
[An] able [husband] outside [working to support a family is] not as good as [an] able [wife] inside [working and saving to take care of the family].

The current meaning is:
Inner strength is more important than outward appearance.

強壯的身體堅強的心態 is the Chinese phrase for “Strong Mind, Strong Body,” however, the character order is actually “Strong Body, Strong Mind,” as that's the more natural word order in Chinese.
