Was it… a) calisthenics? b) calligraphy? Or c) English language lessons?

是a)健美操? b) 书法? 还是c) 英语课？

Yeah, Timber was very curious about why I was doing calisthenics.

没错，Timber 很好奇我为什么做健美操。

If nothing else, focus on calisthenics – these are the basic body movements which everyone can do anywhere, even at home.

如果你什么都不懂，那就专心做健美操——基体动作，在家里或者任何其他地方都可以做。
