The best way to think about this foundational fitness program is not from the details up, but from the top down, from the big picture down to the details, and say to yourself, once a week you're going to get some long endurance in, another day during the week, you're going to make sure that you get a kind of moderate faster endurance workout in, and then one other day during the week, you're going to get an all out sprint, high intensity cardiovascular exercise workout in.
