没沟硬挤伤身体没鸡硬挺伤肾体
[méi gōu yìng jĭ shāng shēn tĭ méi jī yìng tĭng shāng shèn tĭ]
It's an informal and somewhat crude phrase that can be translated as 'Forcing it Hurts the Body'. It implies pushing something beyond its natural limit will cause damage, suggesting the wisdom of acting within one's means or capacity.
