‘强壮’ is an adjective meaning 'strong and healthy', emphasizing both physical strength and robust health. It combines two characters: 强 (qiáng), meaning 'strong', 'powerful', or 'robust', and 壮 (zhuàng), meaning 'sturdy', 'vigorous', or 'in full bloom' — often used to describe youthful vitality or bodily resilience. Together, they form a compound that conveys holistic physical fitness, not just muscular power but also endurance, energy, and resistance to illness.

This word is commonly used to describe people (especially adults and children), animals, or even plants in contexts highlighting natural vitality. It carries a positive, neutral-to-formal register — suitable for medical advice, fitness discussions, parenting, or everyday praise. Unlike the more technical term 健康 (jiànkāng, 'healthy') or the purely muscular 强大 (qiángdà, 'powerful'), 强壮 specifically evokes a well-proportioned, resilient, and energetic physical state.
