workout

Compared meaning: physical exercise, working out (noun).

比较义项：体育锻炼、运动（名词）。

• exercise

  General, often uncountable noun for physical activity done for fitness; neutral to formal register, common in health or medical advice.

  泛指以健身为目的的身体活动的名词，常作不可数名词；语气中性偏正式，常见于健康或医疗建议中。

  Doctors recommend thirty minutes of exercise most days of the week.

  医生建议每周大多数日子都进行三十分钟的运动。

• workout 本词

  Refers to one specific, often planned session of physical exercise; usually countable and informal, common in gym or fitness contexts.

  指一次具体的、通常有计划安排的锻炼，多作可数名词；语气较口语化，常用于健身房或健身语境中。

  I did a quick workout before breakfast this morning.

  我今天早餐前做了一次简短的锻炼。

Exercise and workout both mean physical activity for fitness. Workout usually means one specific, planned session, often at a gym, and sounds informal. Exercise is broader and more formal, often uncountable, and common in health advice. This does not cover workout meaning 'a trial'.

exercise 和 workout 在这个义项上都指身体运动，但语气和用法不同：workout 通常指一次具体的、有计划安排的锻炼（多用于健身房场景），语气较口语化；exercise 是更宽泛、偏正式的说法，常作不可数名词，用于泛指运动这项活动，多见于健康建议中。这里不比较 workout 的“试验，试用”等其他义项。
