How do I zip a folder using the command line while maintaining its file structure?

For example, if I want to zip /Users/admin/Downloads/Backup, and I am at /Users/admin/, I could: zip -r downloads.zip /Users/admin/Downloads/Backup and if I unzip downloads.zip I would get a Users folder and have a Users => admin => Downloads => Backup structure. This is particularly undesirable behavior if I want to create an installation zip file for TWRP. So instead I will have to: cd /Users/admin/Downloads/Backup; zip -r /Users/admin/downloads.zip .; cd /Users/admin/ This doesn’t feel like what a pro would do. What can I do to zip a folder while maintaining its file structure?
