+1 for Rick Beato. His "what makes this song great" series is lovely. I discovered his video on [Bohemian Rhapsody][1] from the same series and then gradually all of his other content.
Even better, System Preferences -> Keyboard -> Shortcuts -> Function Keys; and select the app in which you want the function keys to show up by default. e.g. IntelliJ Idea.
Started with a 5 minute "workout" and selected exercises which are rewarding even if you do them for just 5 minutes. Like burpees, rowing, jump squats, hill climbers.
It really helped that my apartment had a gym that was available to me practically any time I wanted.
