Abstract
Muscle dysmorphia is an emerging condition that primarily affects male bodybuilders. Such individuals obsess about
being inadequately muscular. Compulsions include spending hours in the gym, squandering excessive amounts of
money on ineffectual sports supplements, abnormal eating patterns or even substance abuse. In this essay, I illustrate
the features of muscle dysmorphia by employing the first-person account of a male bodybuilder afflicted by this
condition. I briefly outline the history of bodybuilding and examine whether the growth of this sport is linked to a
growing concern with body image amongst males. I suggest that muscle dysmorphia may be a new expression of a
common pathology shared with the eating disorders. Copyright

Introduction
It has long been recognised that many women suffer
from body image-related anxieties, ranging from simple
unhappiness with shape and weight to a serious eating
disorder such as anorexia nervosa.
In comparison, little attention has been devoted to
the study of men who also display these concerns. In the
sport of bodybuilding, men pursue an idealised muscle-
bound body image as the primary goal of their training.
Developing a healthy body through following an
enjoyable exercise routine is undoubtedly a wholesome
endeavour; nevertheless, it seems that by focussing
overtly upon body image some bodybuilders are led to
crave an unattainable figure. Muscle dysmorphia is an
emerging condition that primarily affects male body-
builders. Such individuals obsess about being inade-
y
quately muscular. Compulsions include spending hours
in the gym, squandering excessive amounts of money
on ineffectual sports supplements, abnormal eating
patterns or even substance abuse.
In this essay, I illustrate the features of muscle
dysmorphia by employing the first-person account of a
male bodybuilder afflicted by this condition. I briefly
outline the history of bodybuilding and examine
whether the growth of this sport is linked to a growing
concern with body image amongst males. I suggest that
muscle dysmorphia may be a new expression of a
common pathology shared with the eating disorders.
What is bodybuilding?
Bodybuilding is the pursuit of a muscular physique
through a regime of weight training and a tailored
programme of nutrition. Although female bodybuilders
exist, it is primarily a male-dominated activity. In the
sport of competitive bodybuilding individuals display

their physiques to a panel of judges, who score each
entrant on the basis of the size, symmetry and definition
of his (or her) musculature. The aesthetic qualities of
bodybuilding differentiate it from the discipline of
powerlifting, where the goal is purely to lift the heaviest
weight possible; in fact powerlifters often carry excess
fat in order to increase the quantity of muscle they can
pack onto their oversized frames.
Perhaps the first ever bodybuilder was Eugen Sandow
(1867–1925), a Prussian who began his career as a
sideshow strongman but soon began displaying his
physique as a work of art. The sport grew slowly
throughout the twentieth century; by the late 1970s the
bodybuilding subculture remained small and largely
overlooked, based primarily around its adopted home
in Southern California.
The world was exposed to bodybuilding in 1977 with
the release of Arnold Schwarzenegger’s cult film
‘Pumping Iron’, a documentary showcasing the body-
building lifestyle as the ‘Austrian Oak’ prepared to take
his sixth Mr Olympia title, the highest accolade in
competitive bodybuilding. As the ebullient Schwarze-
negger rose to stardom as a Hollywood actor, body-
building became accepted into mainstream Western
fitness culture.
Today, many men across the United Kingdom lift
weights as part of their fitness regime. Whilst few may
aspire to the overblown bodies of modern Mr Olympia
competitors, the male fitness industry is booming. In a
quest for toned biceps and ‘six-pack’ abdominals, more
men than ever are joining gyms, reading fitness
magazines and experimenting with performance-
enhancing supplements.

Diagnostic criteria for muscle dysmorphia
What is muscle dysmorphia?
As the popularity of bodybuilding increases, evidence
suggests that increasing numbers of young men are
becoming dissatisfied with their appearance. The nature
of this dissatisfaction is not a desire for smaller and
slimmer bodies, as is most often the case in women, but
rather larger and more muscular ones (Pope et al.,
2000a).
A pathological pre-occupation with overall muscu-
larity and leanness appears to be a relatively new body
image disturbance that primarily affects men. The
condition first entered the literature in 1993 when Pope,
Katz and Hudson described a condition they termed
‘reverse anorexia’ in a population of male bodybuilders.
These men, although they were highly muscular,
believed that they appeared inadequately small and
weak. They declined social invitations, wore heavy
clothes even in the heat of summer and refused to be
seen at the beach. The term reverse anorexia was based
upon the prevalence of past anorexia nervosa amongst
this sample and the similarity in body-related concerns
and behaviours to those suffering from eating disorders.
These men expressed a desire to gain greater
musculature whilst not gaining fat. (Choi, Pope, &
Olivardia, 2002).
Pope and his colleagues have since dominated
research into this entity, subsequently renaming the
condition ‘muscle dysmorphia’, classifying it as a
subtype of body dysmorphic disorder and proposing
the operational diagnostic criteria presented in
Table 1 (Pope, Gruber, Choi, Olivardia, & Phillips,
1997).
Pre-occupation with the idea that one’s body is not sufficiently lean and muscular. Characteristic associated behaviours include long
hours of lifting weights and excessive attention to diet.
The pre-occupation is manifested by at least two of the following four criteria:
(1) The individual frequently gives up important social, occupational or recreational activities because of a compulsive need to maintain
his or her workout and diet schedule.
(2) The individual avoids situations where his or her body is exposed to others, or endures such situations only with marked distress
or intense anxiety.
(3) The pre-occupation about the inadequacy of body size or musculature causes clinically significant distress or impairment in
social, occupational or other important areas of functioning.
(4) The individual continues to work out, diet or use performance-enhancing substances despite knowledge of adverse physical
or psychological consequences.
The primary focus of the pre-occupation and behaviours is on being small or inadequately muscular, as distinguished from fear of
being fat as in anorexia nervosa, or a primary pre-occupation only with other aspects of appearance as in other forms of body
dysmorphic disorder.

Bodybuilding and Muscle Dysmorphia
Why is nuscle dysmorphia
important?
Muscle dysmorphia at its most severe is profoundly
distressing. Some men become so pre-occupied with
muscle development that they will miss social events,
lose their job and even continue training through injury
rather than interrupt their fitness schedule. Unable to
achieve an unrealistic body image, the afflicted body-
builder may spend vast amounts of money on
nutritional supplements and may eventually exper-
iment with anabolic steroids. These drugs produce
rapid increases in lean muscle mass with few immediate
side effects. However, prolonged use is associated with
raised cholesterol, prostate enlargement, male-pattern
baldness, acne, gynaecomastia and testicular atrophy.
Withdrawal from a cycle of steroids can lead to
depression and has been associated with suicide (Pope
& Brower, 2000).
the ontological identity of bodybuilding and its
connection to muscle dysmorphia.
Methods and background
The bodybuilder in question became known to the
author at a local gymnasium, where both undertake
their fitness regimes. Information was collected in
the gym through a series of informal interviews and the
subject gave his informed consent for the material to be
used in this study.
The subject of this study is a 27-year-old male with a
past psychiatric history of depression and bulimia
nervosa. Both were diagnosed and treated by a
psychiatrist using a combination of fluoxetine and
cognitive behavioural therapy. The course of treatment
for bulimia nervosa ended over 4 years ago although he
still takes citalopram for his low mood; for this he
consults his general practitioner. He has not received a
formal diagnosis of muscle dysmorphia because he has
not sought treatment, although he meets the criteria
outlined by Pope in Table 1.
Pope and colleagues (Kouri, Pope, Katz, & Oliva,
1995) have devised a mathematical formula to estimate
a man’s muscularity. The ‘fat-free mass index’ (FFMI) is
calculated using the subject’s height, weight and
approximate percentage of body fat. The resulting
number correlates with the body type of the subject. A
man with a FFMI of 16 would be frail or flabby; a FFMI
of 20 is of average build; one of 23 corresponds to a man
who is noticeably muscular. The authors believe that it
is impossible to achieve a FFMI of over 26 without the
assistance of anabolic steroids, which permit a user to
break through the ‘biological ceiling’ of natural
muscularity. The FFMI of this bodybuilder is 28.
How many people does muscle
dysmorphia affect?
The prevalence of muscle dysmorphia is difficult to
estimate. Pope claims that up to 10% of the body-
builders he has studied exhibit prominent symptoms of
muscle dysmorphia and that the total number of males
of all ages in the USA who have used anabolic steroids
may exceed 2 million (Pope, Phillips, & Olivardia,
2000b).
Amongst a population of bodybuilders, some may
not meet the formal criteria for muscle dysmorphia but
may still be affected by body image concerns that cause
them significant levels of distress. Conversely, many
bodybuilders displaying severely pathological beha-
viour, even those abusing anabolic steroids, may feel
that their activities are simply part of a healthy lifestyle
and will not present to health services.
On discovering bodybuilding:
. . .I
guess I’ve always been fixated with my body shape.
As a kid I was scrawny and I used to envy the popular
athletic boys on the rugby team. I began lifting weights
when I was about 14, using this tiny multi-gym in the
school lunch hour. I discovered I was pretty strong for
my size and quickly I began to see results.

My mates
and I used to mess about on the back seat of the school
bus, flexing our biceps to try and impress the girls;
pretty soon I found had the biggest arms, it made me
feel good about myself.

Why is this study important?
Although Pope and his colleagues have written
extensively about the features of muscle dysmorphia
little has been published on the phenomenology of
the bodybuilding lifestyle. The introverted nature of the
bodybuilding community means that outsiders have
obtained only a glimpse of a significant underground
subculture. Here I present selected excerpts from the
experiences of a male bodybuilder as a means to grasp

Bodybuilding and Muscle Dysmorphia
P. E. Mosley
On past experiences of diet and
exercise:
. . .When
I arrived at university I got into boxing in a
big way. My coach encouraged me to diet down from
70kg to 57kg in my first year so that I could fight as a
featherweight. It was a ridiculous thing to be doing to
my body but that was the only way he would let me
compete. Basically, I had to live on a diet of Slim-Fast
milkshakes, whilst still keeping up this six day-a-week
training routine of running, sparring and weightlift-
ing. I became fixated on food; after a hard training
session I wanted to eat a big plate of pasta like other
normal sportsmen, but I had to content myself with an
apple and protein shake! I checked on the Internet and
my new weight made me officially anorexic, which was
something I was actually proud of at the time because
it proved how hard I’d had to work.
. .
of hours to keep my muscles topped up, even if I’m not
hungry.
. .
When I’m in a cutting phase I’ll restrict my
carb intake to almost nothing so as to lean up and make
my muscles stand out. I read about this carb-cycling diet
in Flex magazine, which some of the top pros use to help
them shred body fat. It does involve controlling every
gram of carbohydrate that you take in each day, which is
frankly almost impossible, but I try to follow it as best I
can.
. .
I do prepare all my food in advance so I can be
sure I’m getting clean calories and I never have to fall
back on junk food from the cafeteria. It is really hard to
keep this kind of diet up and maintain any kind of
normal life, but I persevere because that’s what it takes
to build the kind of body I want.
. .
On steroid use:
. . .I’ve
done three cycles of steroids in the past year. I
don’t see it as cheating, because everyone else in the gym
is using them and besides, even on gear you still have to
put all the hours in at the gym and stick to the same diet,
they’re not magic.
. .
I know steroids are bad for you in
the long run but frankly I’m not that bothered about
how healthy I am in twenty years; I want to feel good
about myself now. And are steroids that much more
unhealthy than living off junk food like most other men
my age? Those people are messing up their bodies too.
. .
The medical profession are always very quick to
highlight the dangers of steroids, but I reckon that’s
motivated just as much by some puritanical desire to
control what people put in their bodies than by hard
fact. My doctor knows no more about anabolic steroids
than the average man on the street whereas I’ve read up
on all the different chemical structures of the various
steroids, how they get metabolised in the body and all
the side effects, so I’ve educated myself and I feel I’ve
reduced the risk.
. .
Although when I came off my last
cycle I got really depressed and even felt suicidal for a
few weeks, which really worried me. But I don’t want to
stop juicing now because I’ve seen the results and I don’t
want to lose that edge.
. .
On current attitudes to weightlifting:
. . .Each
session I concentrate on a different body part; for
example in a given week I might work chest on Monday,
back on Tuesday, legs on Wednesday etc. Splitting the
different muscle groups lets me really blast each one and
allows me to train more regularly without getting
fatigued. For each muscle group, I have a repertoire of
exercises that I’ve picked up over the years, just from
watching other bodybuilders and from reading maga-
zines. I find which ones work for me and stick with them,
but I’m always looking to incorporate new techniques so
as to shock the muscles into growth. I have a little
notebook in which I chart all the exercises I do and the
weights I lift, so that when I analyse my workouts I can
see if I’m getting stronger.
. .
I definitely think about how
the weights I’m lifting are going to affect my appearance.
For example, I might choose to train legs twice per week if
I feel my quads are lagging, or change the angle of a
bench press so that it accentuates my upper chest.
. .
I’m
very serious about my training; if I haven’t pushed
myself to the limit then I feel like I’ve wasted my time. If
the gym is crowded and I can’t complete all the exercises
in my program then I get really irritable...
On quality of life:
On current attitudes to diet:
. . .When
I’m bulking I always try to keep my muscles
supplied with protein and carbs so they can grow. Each
day I’m aiming to eat 3 grams of protein for every
kilogram of my bodyweight, taking a meal every couple

is my life, so I make sacrifices
elsewhere. I’m always thinking about the nutritional
content of food and how it would affect the way I look,
so I can never eat out at restaurants or go to a friend’s
for dinner because it would mess up my diet. And I

spend so much money on stuff like protein-powders
and fat-burning pills that I have no money left to go
out drinking; to be honest I don’t have that many
friends anyway. Not enough time for them.
. .
I often
arrive to work late or leave early because I have to
train, and even when I am there my mind is always on
my next meal or gym session. I guess my ideal job
would to be a personal trainer, then I could just live in
the gym.
. .
On muscle dysmorphia:
. . .Do
I have a problem? I guess so. I sometimes wonder
what the point of my life is. I work so hard at my body
but underneath I still hate the way I look. In my mind I
know I am bigger than most of the guys on the street
but I still feel inadequate. I don’t like undressing in
front of my girlfriend and I don’t enjoy sex because I’m
too busy worrying about the way I look. Even just
looking at my body in the mirror when I come out of
the shower makes me feel horrible.
. .
Is muscle dysmorphia a type of
eating disorder?
Individuals with muscle dysmorphia demonstrate a
specific maladaptive pattern of behaviour, namely an
obsessive drive to exercise and to restrict their diet. As
mentioned previously, Pope and his colleagues origin-
ally labelled muscle dysmorphia ‘reverse anorexia’
based on the apparent links between the two conditions.
Nevertheless, Pope’s proposed diagnostic criteria for
muscle dysmorphia categorise it instead as a subtype of
body dysmorphic disorder, defined as a pre-occupation
with an imagined or exaggerated deficit in appearance
that has the characteristics of an overvalued idea, is not
amenable to re-assurance and leads to significant
distress plus impairment of functioning. In the tenth
version of the International Classification of Diseases
(ICD-10), body dysmorphic disorder is classified in
section F45.2 as a hypochondriacal disorder, which thus
groups it with a diverse range of presentations known as
‘somatoform’.
This shift in nosology seems to be based upon the
profound distortion of body image present in those
severely affected by the condition, coupled with the
dominance of pathological exercise behaviour over
abnormal eating behaviour alone. Olivardia’s (2001)
phenomenological analysis contends that in the
anorexic patient, the primary disturbance is one of
eating, to which may be added excessive exercise as a
secondary characteristic. The reverse applies to the
patient with muscle dysmorphia.
The overwhelming feature of the somatoform
disorders is the generation of medically unexplained
physical symptoms (somatisation). This is not a
principal feature of either body dysmorphic disorder
or muscle dysmorphia. Some academics have already
suggested that body dysmorphic disorder might be
more appropriately conceptualised as an obsessive-
compulsive spectrum disorder on the evidence of an
overlapping psychopathology—namely intrusive,
obsessional fears and compulsive rituals (Philips,
Gunderson, Mallya, McElroy, & Carter, 1998). Body-
builders with muscle dysmorphia also report pre-
occupations and obsessional thoughts about muscu-
larity as well as compulsive exercise and checking of
muscularity (Olivardia, 2001).
A study by Maida and Armstrong (2005) used
validated questionnaires to assess committed male
weightlifters on measures of muscle dysmorphia,
tendency to somatise, features of obsessive-compulsive
disorder and characteristics of disordered eating,
amongst others. Not only did the researchers identify
that symptoms of muscle dysmorphia are strongly
related to certain measures of eating disorder (body
dissatisfaction and perfectionism) and obsessive-
compulsive disorder, but also that symptoms of muscle
dysmorphia were not at all related to somatisation.
The fact remains that the distinctive cognitions and
rigorous lifestyle of the obsessive bodybuilder in his
pursuit of bigness parallel the phenomenology of the
man with an eating disorder in his pursuit of thinness. I
suggest that if the core psychopathology in anorexia
nervosa is over-evaluation of eating, shape and weight; a
similar over-evaluation occurs in muscle dysmorphia,
but in a different direction. Both disorders value
leanness and demonise adiposity.
Men with anorexia nervosa, bulimia nervosa and
binge eating disorder consistently show marked
dissatisfaction with their body image (Olivardia, Pope,
Mangweth, & Hudson, 1995). Bodybuilders, although
concerned with gaining muscle rather than losing fat,
also display an increased pre-occupation with their
body image, food and exercise (Mangweth et al., 2001).
An examination of the severe dieting practices prevalent
in the sport of competitive bodybuilding indicates that
such men are at increased risk of developing a
