I need to "hit the gym" to git gud. Can anyone give me a training regimen, good YouTube resources, etc.?

Playground mode is perfect for training muscle memory on learning good building-habits, practicing 90-degree turning, quick-edits, etc.

I'm sick of being bad when I'm otherwise good at other FPS games like Siege or Planetside 2. But I know that Fortnite has an insanely high skill cap and a lot of it is building and out-maneuvering.

Is there any content out there, like YouTube tutorials and such, that are tried-and-true good bread-and-butter things? etc.

I appreciate the help!
