It has been was raining for hours in the early morning.
Of course, Absolutely, I was got caught in the rain. But I must should try to enjoy rainy days. Certainly, the weather forecast says that rainy season is coming and it will last for about a few of weeks in the south of China. It means long hot days follows will come later.

I got up about 5 am today, and then go went to the playground, where a few people are were running and it seemed like so quiet and peaceful. I get used to usually do some push-ups that can increase the strength of my limbs. If I have powerful limbs, I can learn many high-intensity sports better and protect myself when I go out alone.

A few notes:
1. Good job!
2. It's technically correct to say you "were/was caught in the rain" but sounds more natural to say you "get/got caught in the rain".
3. It's not a direct translation, but usually instead of saying the "strength of your limbs" you would say "upper body strength" for chest and arms or "lower body strength" for legs.

Hope that helps!
