Xiaomei, what exercise did you do today?

I went running, and I played ball too!

That's great. Did you run fast?

I ran fast at first, but then I got tired.

When you feel tired, you should slow down or take a short break.

I also ran back and forth while playing ball and sweated a lot.

That shows you exercised very seriously.

Even though I was tired, I thought it was really fun.

Knowing how to exercise and how to rest will help your body stay healthier.
