Not OP but: IDE: Use IntelliJ Community Edition (or whatever Jetbrains IDE matches your project). Print out a keystrokes cheat sheet and tape it on your desk.

Not OP but: IDE: Use IntelliJ Community Edition (or whatever Jetbrains IDE matches your project). Print out a keystrokes cheat sheet and tape it on your desk. Try to do stuff as a series of snippets, autocorrects, autocompletes and refactorings rather than pounding out the code (this is especially relevant in Java where it can save you like 90% keystrokes). Example: don't start a new method by writing the new method. Start it by calling it somewhere with arguments, then alt-enter (auto-correct) to create the method, with the types and arguments already filled in. Chair: get Herman Miller Aeron or Mirra (cheaper), second hand Standing desk: I use cardboard boxes on a regular desk. I take sitting breaks when I'm thinking but not actively typing. Pomodoros also work (stand 20, sit 5 or 10). Don't use your phone when you sit.
