Boxers can u tell me how to get into shape for boxing training at home?

Now I know that people say we'll you'll get into shape in the gym but i read how fraziers book and he recommended getting into shape before u go to the gym . Now I'm not asking for technique training that i know u should have a professional show u correct techniques but what about the strength and conditioning training ? How man miles should I run ? How many days a week ? Jump rope ? Do U do that directly after the run ? Or do u weight till like a few hours pass ? I just need kinda a layout schedule of how to properly get into shape to repair myself to go to the gym . Ty
