ร่างกายแข็งแรง

Explanation

This expression consists of ร่างกาย “body” and แข็งแรง “strong, robust, or healthy.” It can form a subject–description structure meaning “the body is healthy and strong,” or function within a larger phrase referring to “a healthy, strong body.” It emphasizes lasting physical condition, strength, and proper bodily functioning rather than a passing sense of feeling well. It is natural in everyday conversation, health advice, and good wishes.

Usage

Commonly used when discussing the benefits of exercise or nutrition, describing someone’s physical health, or giving advice about staying healthy. ขอให้ร่างกายแข็งแรง is also a common wish for someone’s continued good health on birthdays, at New Year, or on similar occasions.

Caution

This is not the usual expression for saying “I’m fine” in response to a greeting; สบายดี is normally used for that. ร่างกายแข็งแรง specifically emphasizes physical health and robustness, and it does not necessarily mean muscular.
