A lot of body-image issues are [[AlwaysFemale related to/centered around femininity]]. Thus, we have tropes such as ACupAngst, HollywoodHomely/[[HollywoodPudgy Pudgy]]/[[HollywoodThin Thin]], FatGirl, and so on. But the same way that thinness and breasts are associated with femininity, muscles are associated with masculinity. Thus, this trope, in which a character angsts about having not enough or too much muscle. There are two versions:

* '''Not Enough Muscle''': The AlwaysMale version. A weak or skinny male character angsts about not being muscular. The focus may be on how this affects his [[WomenPreferStrongMen success with women]], his usefulness in sports/combat, or his attractiveness. If the focus is on his success with women, WeaknessTurnsHerOn may come into play as a solution/counterpoint. Unlike breast size, [[ACupAngst which is mostly unchangeable]] without surgery, it is possible to build muscle, so whether this trope is [[JustifiedTrope justified]] or not depends on there being a health reason for the male being incapable of doing so.
* '''Too Much Muscle''': The AlwaysFemale version. A female character, usually an ActionGirl worries that her muscles are [[BrawnHilda unattractive to men]]. This version is similar to NoGuyWantsAnAmazon. Just like WeaknessTurnsHerOn may come into play in the first version, AmazonianBeauty or AmazonChaser may come into play in this version.

[[folder: Advertising ]]

* The ad for Charles Atlas where a bully (inadvertently) kicks sand in the face of Mac and his gal. Allegedly this actually happened to the real Charles Atlas before he started doing dynamic tension. A side note: according to several sources, Atlas built his physique with conventional weightlifting, and then devised dynamic tension because he figured it would be easier to sell to young boys with plenty of Muscle Angst but without the resources to buy barbell sets or go to a gym regularly. The failure of dynamic tension to actually work wasn't a sales problem in the days before internet forums.
* Mixed with ACupAngst in an ad manga for Chasteberry E breast enlargement pills: the small-breasted person tries out all kinds of hoo-hah gimmicks to make her breasts grow, including drinking milk, using a suction device, and doing dumbbell exercise... The last one of course does nothing to increase her mammary mass but gives her muscled arms, which she regrets.

* ''Manga/{{Claymore}}'' has Undine, who always looks like an amazon warrior ready to rip your arms off if you so much as glance at her wrong. [[spoiler: She is actually just as lithe as the rest of the Claymores, but she lost a friend long ago, and channels her Yoki into her muscles to keep up a strong appearance for the other Claymores.]]
* The comedic manga ''Manga/ShortCuts'' has a story in which a typical "kogal" gets trapped in a sumo wrestler costume and is forced into actual sumo competition. Eventually, she manages to get the zipper unstuck, only to find out all that exercise has made her unfashionably muscular. Not to worry though, a passing man still wants her... for the military!
* [[CuteBruiser Biske]] of ''HunterXHunter'' explains that the reason that she stays in her SleepModeSize is that her regular form is "too bulky".
* Casca from ''Manga/{{Berserk}}'' complains that the [[PimpedOutDress fancy, frilly gown]] she dressed up in for a ball looks weird because she's too muscular. Now Casca is toned, but the fact that [[SheCleansUpNicely every male character thought she looked irresistible]] proves her wrong.
* Variation in ''Manga/PokemonSpecial''. Ruby claims that he doesn't train his Pokemon for battles in fear that they will gain ugly muscles. [[spoiler:Looks like to be a case of MusclesAreMeaningless, as it turns out his Pokemon are in fact very powerful and well-trained.]]
* One guy in Manga/FrankenFran keeps getting picked on by bullies, so he goes to Fran for help. He ends up bulging with muscle... and still gets beaten up.

* ([[GenderFlip Female]]) [[LightNovel/InfiniteStratos Ichika Orimura]] in ''The Mirrorverse'' has a little bit of this, due to her [[TrainingFromHell intense physical regime]] caused her body to grew rather muscular. Understandable, since every other Cadet Rep [[{{Fanservice}} looks like supermodels]] (or [[CuteBruiser unbelievably petite]]). Either way, [[UnluckyChildhoodFriend Dan]] doesn't give a damn, while [[ScrewYourself her male counterpart]] flat out said it's a sign of her effort and should be appreciated.

* In ''Film/TheRockyHorrorPictureShow'', Dr. Frank-N-Furter created Rocky because he wanted a man with muscles. Frank insults Brad's lean build, and Brad's fiancée Janet replies that she doesn't like a man with ‘[[ArtisticLicenseBiology too many muscles]]’[[AudienceParticipation Just one big one!]]. [[SubvertedTrope She somehow quickly changes her mind by the end of the song, just about a minute later, singing, ‘I’m a muscle fan.’]]
* Steve Rogers, whose health problems and weak build keep him from joining the army and getting girls, before he becomes ''[[Film/CaptainAmericaTheFirstAvenger Captain America]]''.

[[folder: Literature ]]

* Keladry, the protagonist of ''Literature/ProtectorOfTheSmall'', training to be a knight, is big and tall and develops muscle, as you might expect. There's a scene where someone takes her by the StandardFemaleGrabArea and she flexes her bicep so that it swells and forces his hand open. [[TheBully Joren of Stone Mountain]] tries to make her insecure about that, claiming she'd be pretty if she stopped working out, and she flatly ignores him. At times - worrying about love interests - she thinks they probably prefer small girls, but being a knight means a lot more to her than maybe "attracting" a man, and no one but Joren evidences disgust.

[[folder: Live Action TV ]]

* The 2005 Creator/{{TLC}} documentary ''The Man Whose Arms Exploded'' looks at an extreme degree of male MuscleAngst leading to [[PsychoSerum steroid abuse]] and (in the case of bodybuilder Gregg Valentino) ''injecting oil'' into the biceps. Can be seen starting [[http://www.poetv.com/video.php?vid=49645 here]] (warning: some NauseaFuel and a fair bit of bad language).
* DragQueen and ''Series/RupaulsDragRace'' finalist Courtney Act gets the worst of both worlds. On the show she talks about feeling too skinny as a man compared to the [[GymBunny gym bunnies]] of [[{{Gayborhood}} West Hollywood]]. But as Courtney, she worries that bulking up would hurt her image, since she's known for looking like a [[http://www.gettyimages.com/detail/news-photo/courtney-act-attends-the-rupauls-drag-race-season-6-party-news-photo/470551315 natural modelesque woman]].

* Peter Fox of ''{{Foxtrot}}'' sometimes stresses about not being able to gain any muscle due to his superhumanly high metabolism. One sunday strip had him and his friend Steve cramming a huge work out session into one day to prepare for going to the pool the next day. Unfortunately, the next day they're barely able to move due to being so sore.

[[folder: Video Games ]]

* ''VideoGame/SuperRobotWarsOriginalGeneration'': [[VideoGame/SuperRobotWars3 Lune Zoldark]] complains that, regardless of her diet or exercise routine, everything she eats turns to muscle.
* The Sports Club Manager Arcana from ''{{Persona3}}'' has a case of this. She's tanned and toned, but other girls tell her that NoGuyWantsAnAmazon. A likely case of TruthInTelevision as the game takes place in Japan, and girls (currently) avoid tans and aim for that "fragile" kind of thin.
* Inverted by Guan Yinping in ''VideoGame/DynastyWarriors 8'', when beaten, she thinks that she ''doesn't have enough muscles''. She's also the kind of girl who admires muscles a lot.

* Saber in ''FateStayNight'' thinks she's too muscular. Not that you can tell by looking at her. Some promotional artwork of her leads to InformedDeformity.

* A ''{{Vocaloid}}'' [[http://www.youtube.com/watch?v=HSQZ4_LsPUs fan video]] by Kagome-P had Gakupo depressed over his lack of muscle mass, and his story of emulating figures such as [[Manga/FullmetalAlchemist Alex Armstrong]], [[UltimateMuscle Mantaro Muscle]] and an assortment of anonymous, heavily muscled figures in order to woo the girl of his dreams. [[spoiler: This backfires at the end of the video, when he discovers that she's now into skinny guys and his struggle to get a toned body was for nothing.]]

[[folder: Western Animation ]]

* ''WesternAnimation/TheSimpsons'': The episode where Marge goes into bodybuilding had her obsessed with gaining muscle, despite being very muscular even for a man.
* The first ever CutAwayGag in ''WesternAnimation/FamilyGuy'' showed a skinny and weak AdolfHitler in a gym glaring angrily at a [[MatzoFever musclebound Jewish man surrounded by beautiful women]].
* A long running desire of Ren from ''WesternAnimation/RenAndStimpy'' was to get pectoral implants. In one episode he finally does...using the fat from Stimpy's butt.
* An episode of ''WesternAnimation/SpongebobSquarePants'' had Spongebob ordering inflatable muscular arms after realizing how skinny he is. Too bad for him that they don't actually increase his strength.
* A very early episode of ''WesternAnimation/SouthPark'' features [[FatBastard Cartman]] winning an essay contest and getting to be on TV show. It's PlayedForLaughs when he sees a commercial advertising a weight gain supplement, and worries that he's too thin when the commercial asks the viewer if they're tired of being a 90-pound weakling (With Cartman estimating that he weighs about 90 pounds - in a third-grader's frame). He gets a supply of the supplement, and bulks up to Jabba the Hutt like levels. He thinks he looks awesome, but anyone else who sees him just says "Goddamn, that's a big fat ass!"
* One episode of ''WesternAnimation/BeavisAndButthead'' has the duo trying to gain a protein shake in hopes that it'll make them more attractive to chicks. After failing to order the actual thing (Since they don't have any money) the two go over to Stuart's house and make their own drink using random food from his kitchen. The drink is thoroughly disgusting, but doesn't actually make any difference. The two try exercising for awhile, but quit because it's too hard.
