Noun and する verb
うんどう

When you carry your movements (or carry something along with your movements, like weights, for example) you are doing exercise. Speaking of which, perhaps you've been studying kanji a little too much lately. Time to get up and do some squats.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
