FTM- What’s the easiest way to get through a door with a stroller (when no one else is around to open the door)?

Please include answers for push doors and pull doors.

Push door:

Do you push the door open open with one hand and push the stroller through with your free hand?

Or do you reverse through the door and use your back to open/hold open the door?

Pull door:

Do you pull the door open with one hand, hold it open with your foot/body, then push the stroller in? Is there another way for pull doors?
