If the place is close.

It's just sweatpants.

Feel cold

Just warm up at home first.

Don't wear tight upper body.

Choose a vest (provided the indoor temperature is high)

If it is cold indoors, wear long-sleeved loose clothes and a thicker coat outside.

It will be colder in a few days.

Suggested down jacket

Take off your coat when you go to the gym to warm up, and put on your coat after exercise.

You won't catch a cold.
