Heres a book, but the workout is 3-4 months long. But it pays off. Its The Complete Guide to Navy SEAL Fitness. If you did this, you would crush any test that the regular army would give you.

As far as endurance, eating the right carb meal can help out alot. Maybe some caffeine also a boost.
I know creatine helps with weight training endurance, but Im not sure about running endurance

Also, something else that works and isnt just some crap is something called the PowerLung.
