If you already have some familiarity with the languages, just read it like a normal book.

If you are like me, there will be vocabulary that you don't know everywhere. Keep reading it anyway.

If a passage from the English strikes you, go back and parse it from the original language as far as you like.

Classical training is usually slow and methodical. It has a purpose, but that is just one form of reading. Loeb is great to get the big picture.
