If you don't want to go to the gym, you can also find friends to play badminton, or skate, or go to a disco, or climb mountains. These activities should last 1 hour unless you don't like them.
As long as you find your favorite sport, you will definitely feel that 1 hour is not enough. I can't stand 10 minutes if I just jog, climb stairs and jump rope alone. It's so boring.
Hehe, to say the least, girls often walk around all day, which is also exercise. Of course, stop as little as possible, don't eat too many snacks, just drink some water, so that they can lose weight at the end of the day.
