The first thing you need to understand about your running body is that everything is connected to everything else.
Muscles are connected to bones by tendons. Your lungs are connected to your cells by your bloodstream. Your brain is connected to your hamstrings, calves, and Achilles tendons by your nervous system. And fascia literally wraps almost every inch of your body in one continuous weave.
No part of your running body is an island.
Instead, your body is the ultimate team. And your team’s players are your running “components”: your muscles, connective tissue, cardiovascular system, powerhouses (mitochondria), pH control, nervous system, energy system, hormones, and brain. Each of these components contributes to every stride you take. And to run your best, you’ll need to train each to its maximum potential. Unfortunately, there isn’t a single workout (e.g., a long run) that benefits all of your components equally. Just as you wouldn’t train an NFL lineman the same way you’d train a quarterback, you’ll have to target each of your components with training specific to its role in your running.
Naturally, there will be overlap with workouts. Your goal isn’t to completely isolate each component from every other. It’s to train each component to 100 percent of its potential, then to integrate it into the working whole that is your running body in motion.
You’ll note that the chapters of Part Two are further broken down into the physiological parts that make up each component. For instance, running muscles will be broken down into slow-twitch, intermediate fast-twitch, and fast-twitch muscle fibers (cells). You’ll learn a little about the physiology of each part, including its function in your running. This will be followed by a “Training Recommendation” section that suggests specific workouts for targeting that physiological part—all the exercises, stretches, drills, etc. featured in these training recommendation sections will then appear in the photo instruction for that chapter (unless they’ve already appeared in another chapter, in which case you’ll be directed to the appropriate page number).
For sample training schedules incorporating workouts for all of your components, turn to Chapter 15.
