⚖️ 体 (body) + 重 (heavy/weight) = body-weight
体 means body and 重 means heavy or weight, so 体重 literally reads as body-heaviness — the standard term for how much a person weighs. 重 also appears in 重要 (important) and 体重计 means a bathroom scale.
重 — person 人 + east 東 (phonetic)
Originally depicted a person carrying a heavy bundle on their back, suggesting weight and burden. The 東-like element served as a phonetic component. Over time the character split into two readings: zhòng meaning 'heavy' and chóng meaning 'repeat/again'.
