While I agree entirely that CFTS is the best introduction to Charlie’s methods, I dont think it will give the OP the information he needs to really get started on a practical level. Esp since a lot of the workouts taht were listed seemed to be for Charlie’s more advanced guys
That’s where I think GPP will benefit him the most, by showing him drills, exercises, progressions to start getting into shape to be able to sprint in the first place. As much from a technical as a conditioning point of view.
Learning good sprint mechanics out of the gate will do as much for him in the long-run as anything else. And that’s hard to pick up from any book.
