The Central Nervous
System (CNS) Workout
By Pete Sisco
IMPORTANT
This program involves a systematic progression of muscular overload
that can lead to lifting very heavy weights. Proper warm up of
muscles, tendon, ligaments and joints is mandatory at the beginning
of every workout.
Although exercise is very beneficial, the potential for injury does
exist. Precision Training, LLC and its owners, agents, affiliates and
employees are not liable for injuries sustained while lifting, using or
moving weights and exercise equipment in a gym or elsewhere.
Always consult with your physician before beginning any program of
progressive weight training or other exercise.
If you feel any strain or pain when you are exercising, stop
immediately and consult your physician.

Introduction
Here is a quick lesson in hubris. Or: how I learned that I can be just as blind
as everyone else.
Way back in 1992 when I was just getting serious about lifting weights I
was surprised to learn how unscientific the whole enterprise really was.
Everyone in the gym just seemed to be doing a random routine using
whatever equipment was not in use, they didn't write down what weight
they lifted or how long it took to complete an exercise.
That was the most shocking thing to me -- nobody seemed to keep track of
time! Many people talked (and talked and talked!) about "intensity" but I
knew from studying physics that the measurement of intensity of muscular
output must be measured with time. Soon I developed the Power Factor
measurement so a person could go from saying " I bench press 325
pounds ", to saying the more precise and meaningful, " I bench press 2,800
pounds per minute ."
This innovation led to others which all basically focused increasing the
intensity and efficiency of both individual exercises and complete workouts.
So I was pretty proud of myself for noticing that in 100 years of strength
training and bodybuilding nobody before me had really focused on
measuring intensity in a precise way. I wondered how everyone missed it.
Then 10 years later...BAM!...I suddenly realized I'd been missing another
big piece of the picture…just like everyone else had.
Central Nervous System
I've optimized workouts for every major muscle group in the human
body...but I completely missed the most obvious and important
component in stimulating new muscle growth: the Central Nervous
System. The CNS is the master switch in the human body that determines
whether ANY exercise for ANY muscle group is effective. In short, if the
CNS has not switched the body into an anabolic state there will be no new
muscle growth. Period.
For example, if you do triceps exercises at an intensity that is high enough,
your brain will in effect say, “ This workout is very demanding and it taxes
the body’s resources too much so I need to send signals through the body
to build more muscle in those triceps .” That is the body’s way of protecting
itself. It adapts to stresses so next time the stress occurs the body is ready
for it. But it only adapts if it truly needs to. Do a wimpy triceps exercise and
your CNS will not trigger new muscle growth.
But when you work an individual muscle to failure – even successfully - you
are nowhere near the level of intensity the entire Central Nervous System
can withstand.
So what is needed is a workout optimized to signal the CNS to kick the
entire body into anabolic mode.
Purpose of the CNS Workout
It's important to understand what we are doing with the CNS Workout. To
illustrate our objective, let's take the example of arm training. Suppose you
wanted to create a workout for the major muscles in your arms; the biceps,
triceps and forearm muscles.
If the workout you designed used bench presses, lat pulldowns and
deadlifts it would yield some benefit to your arms. The bench press works
your triceps a little but it's primarily a chest exercise. The lat pulldowns
work your biceps a bit if you bend your elbows and pull all the way down
but it’s primarily an upper back exercise. And holding a heavy bar for
deadlifts will exercise the gripping muscles of your forearms but it’s
primarily a lower back exercise.
So you can see that the above workout is not optimized for the arms. Yes,
it will work...but it won't work best .
The same thing happens when we do our normal workouts (even my
optimized PFT and SCT workouts)...they are engineered to target individual
muscle groups with the maximum intensity possible, but they are NOT
engineered to signal the CNS to switch to maximum anabolic mode.
Why? Because you can’t do both at once! You need a separately
engineered workout for each objective.
Eureka! How did we miss that for 100 years? I even searched the Internet
looking for a workout targeting the CNS instead of targeting legs or
shoulders or whatever. Nothing. I've never read nor heard anybody talk
about a workout engineered and optimized to target a maximum CNS
response.
So this is a very new and powerful concept and, as I mentioned, it is
important to understand what your objective is in the gym because the CNS
Workout has two unusual characteristics:
1. The exercises do not target a specific muscle group
2. The workout is far more demanding than a normal workout
The Exercises
The way to stimulate the growth of new muscle is to force them to operate
at high intensity. That intensity is measured in work per unit of time. So the
way to maximize intensity is to do a great amount of work is as brief of time
as possible. This same stress is what triggers the Central Nervous System
to switch into anabolic mode. The CNS Workout aims to deliver the
highest possible systemic intensity by forcing the largest muscle groups
of the body to work "all out" in rapid succession.
These are the muscles we will use to overload the CNS:
Triceps - the largest muscle of the arms
Pectorals - the large muscles of the chest
Spinal Erectors and Hamstrings - the powerful muscles of the lower back
and upper legs
Trapezius - the strongest muscles of the shoulder girdle
