Mostly anything that is outdoors or requires physical activity.

Do some cool sport like table tennis, curling or fishing

Do you like to do things? If so you have hobbies. For "normies" even netflix is a hobby, regardless of whether or not It's healthy or not.

If you want to impress people with your hobbies then explore interests of yours with more flare. For example, if you like photography you could go on hikes and trips and show people cool pictures of your travels.
