a sweat during your marathon session. What if I told you that new exer-
cise theories suggest that you may be able to burn the same amount of
calories with less time trudging away at the gym if you worked in some
short bursts of high intensity? Well, get ready to be outraged (in the best possible way). Low-intensity, super-long sessions may be your opportune
time for getting through a huge stack of magazines or watching your
favorite TV shows, but there may be a way to get more out of your work-
out than catching up on the latest
Real Housewives
drama.
The truth is, some scientists believ
BOOKS,
e that “long and slow” is not the
best fat-burning formula. New theories regarding how the body burns
off sugar and fat (both are forms of energy) suggest that when you get
yourself into a high-intensity zone for short periods of time (“bursts”), you ratchet up your body’s fat burning significantly. Translation: this
type of exercise could help you accomplish more in less time.
So, let’s get efficient.

Scoring
For every question that you answered “a,” give yourself 0 points, for
every “b” answer give yourself 2 points, and for every “c” answer, give
yourself 4 points.
0 to 10: Sedentary
If your score is this low, you should no

Exercise Program. Instead, you need to make it your immediate goal
to start walking more. Walk around the room when you’re on the
phone, park farther away from the entrance to buildings, walk in cir-
cles around the living room while watching TV. Wherever, however,
and whenever you possibly can, get on your feet and move around.

If you’re in this range, you are already making certain efforts to incorporate physical activity into your life, and I’m going to ask you to
step it up a few notches. You should ease into the program below, but
be extremely cognizant of your perceived exertion, which I’ll explain
shortly. Do not try to go from 0 to 60, but build slowly on the base

Seek Your Doctor’s Permission
Regardless of your current physical activity level, I am t

elling you
in no uncertain terms that you need to discuss this exercise pro-
gram with your doctor before you start it. This is not an option;
it’s required.
If you have any preexisting conditions that could be affected or
exacerbated by activity, or if you’ve been extremely sedentary for
a long time, then you need to take certain steps before you even
attempt this program. If you don’t, you might be setting yourself
up for a cardiac event such as a heart attack.
This isn’t just some throwawaBOOKS,

vascular system is healthy, then exercise can help maintain
your health. But if it’s not, then heed your doctor’s advice.
Rate of Perceived Exertion (RPE)
Before we get int
STREET
o the specifics of this innovative form of exercise, I
want you to start tuning in to your body. So many people just trudge
their way through their day (or their life), barely aware of their sur-
roundings, much less of the cues their own bodies are giving them.
But when you really wake up, pay attention, and start listening, you’ll
be a
BIRD
mazed how many messages your body is trying to send you.
For example, the Hunger and Fullness Scale has shown you to
discern when you are
physically
hungry and when it’s just fake hunger, conjured by your mind in response to some kind of trigger. You’ve
learned about the physical symptoms you experience when you truly
need food, such as a growling stomach or light-headedness. Similarly,

The World Health Organization and the Surgeon General rec-
ommend that adults get a minimum of 150 weekly minutes of
moderate-intensity physical activity (e.g., walking, dancing, light
swimming) or 75 weekly minutes of vigorous activity (e
INC.
.g., run-
ning, cycling, fast swimming). If you do this you’ll experience
some health benefits, but for even better results and weight loss,
the recommendation is to shoot for 300 minutes of moderate-
intensity activity or 150 minutes of vigorous activity per week.
But if you’re currently living a sedentary lifestyle, all that activ-
ity probably sounds overwhelming and unrealistic. Well, before you
decide it’s out of the question, here’s some good news. A study in the
journal
Preventive Medicine
showed that sedentary adults who complete short bouts of light to moderate p
BOOKS,
hysical activity (such as walk-
ing briskly around the block) for just six minutes at a time, five times per day, can experience similarly significant improvements in their
overall physical fitness as people who complete one, continuous bout
of exercise. You know the old joke about how to eat an elephant? One
bite at a time. It’s the same with exercise. You don’t have to do it al
at once, especial y when you’re first starting out.
I’d like you to bec
STREET
ome acutely aware of another set of indications, or
signs, that your body is giving you on a daily basis, and these have to
do with your physical exertion.
There’s been quite a bit of discussion in the exercise community
about whether a heart rate monitor gives you any more of an advan-
tage t
BIRD
han simply self-monitoring your “rate of perceived exertion”
(RPE). Basically, your RPE is your built-in system for judging your
own physical output. I’m talking about heavy breathing, rapid heart
rate, sweat, a feeling of fatigue in major muscle groups, and so on.
Your mind perceives how much you’re moving, whether you’re sitting
as still as a statue on the couch or running full out on a treadmill.
134 | The 20/20 Diet
Below is a version of an RPE scale that I have adapted from the
Borg Scale of Perceived Exertion and expanded upon so that you can
rate your level of energy expenditure without any extra gear like a
heart monitor. This is meant to help you understand when you are
“exercising” and when you are seriously
exercising
.
Judging Your Perceived Exertion
0
No movement; sitting still; neutral.
INC.
1
Extremely light exertion: Almost no sign of energy expenditure.
2
Light exertion: Very comfortable, no detectible increase in heart rate or respiration.
3
Mild exertion: Feeling slightly warm, a slight increase in
breathing.
4
Medium exertion: Hear
BOOKS,
t rate and respiration both noticeably
higher.
5
Moderate exertion: Starting to sweat, breathing pretty hard, but still able to carry on a conversation.
6
Significant exertion: Sweating steadily, breathing is steady but hurried. Talking is getting slightly harder but is still possible.
7
Medium/high exertion: Feeling hot all over, sweat is dripping
and sho

wing through your clothes. You can maintain this level
for a while, though. Your body is not screaming for you to stop.
8
Hard exertion: Starting to feel uncomfortable, but you feel like you can go for a few more minutes like this.
9
Intense exertion: You don’t feel like you can maintain this level very long. You can get out a couple words if you have to, but
BIRD
definitely not a conversation.
10
Extremely intense exertion: Very heavy breathing, heart rate is extremely high, and you cannot speak. The hardest you’ve ever
pushed yourself physically—so much so that you can’t keep it up
another second.

Keep in mind that you may not experience the same signals of
exertion as someone else. For instance, a marathon runner would
likely be at a 1 or 2 when walking briskly, while someone who isn’t
in shape would be at a 5 or 6 when walking at the same pace. That’s
why this is an ideal method to determine
your
exertion, because it’s tailor-made to you and it will change and evolve as you increase your
level of daily physical activity.
When I first started doing the high-intensity exercis

e bursts you
will soon read about, I found out very quickly that you don’t just go
from 0 to 10 in one swift shake of your tail feathers. It takes serious
labor to work your way up this scale. So, when you start to learn about
the burn bursts in this program, keep in mind that your 30-second
clock doesn’t start ticking until you’ve reached an 8 or 9 on the RPE
scale, and it may take you a couple minutes to get up there.
For me, the best way to apply this exercise regimen is on a stationary
bicycle. I just keep increasing that resista

Anaerobic and Aerobic Exercise
You’ve probably heard of aerobic exercise. Now we often refer
to it as “cardio,” but you might remember the days of aerobics
classes. Essentiall

y, aerobic activity occurs in the presence of oxy-
gen, and it uses both glucose and fat for fuel. Anaerobic exer-
cise, however, does not need oxygen—instead, it uses glycogen,
which is the sugar stored in your muscles, as its fuel. This type of
activity builds muscle tissue, which we know to be metabolically
active and excellent at burning fat. When you perform the type of

30-second bursts are considered anaerobic activity.
So, which type of exercise is best for burning off fat and cal-
