As someone who knows almost nothing about muscle building, why would I want to work specific muscles? How do I know which muscle I should want to work? Do I look at a particular muscle and feel it's too small and that's how I choose? Do I target specific muscles that feel sore after I do some other activity that is the real activity I value? I'm genuinely curious. If this website is giving the "how", I want to know the "why".

In my experience, I’ve received answers to these questions working with a physical therapist. I’ve sustained several injuries partly due to muscle imbalance (that led to poor walking mechanics due to glute imbalance). So we try to correct that imbalance with strengthening exercises that target the glutes.

I've been dealing with similar issues. Can I ask how long it took for you to start seeing results from the strengthening exercises, both just in strength and your injuries going away? It's easy to see progress in weightlifting etc, but bands or body exercises for small muscles (adductors, in my case) just always feel hard.

I had issues with pain from squatting not because my glutes were too weak but because I was not activating them properly as stabilizers, AKA dead butt syndrome. From that perspective the main importantce of bands, or bridges or whatever is to teach the body to properly use the small stabilizer muscles that can get inadventently inhibited due to injury or underuse, not get them super huge or much stronger so it really shouldn’t take long, weeks to a month I’d say.

It's hard to separate actual progress from placebo so hence hard to give a good time estimate, but I'd say 3 months in I was at my peak (I've fallen off since then and ultimately "failed" PT in terms of it helping to address my specific issues).

If you're starting out with training, the general recommendation is to do big compound exercises (if you're powerlifting things like barbell squat, barbell deadlift, barbell bench press; if you're doing calisthenics things like push-ups, bodyweight squats, etc.). Once you're able to go through the motions of those, it's possible to identify which part of the exercise you're not doing so hot at, e.g. if you were doing bench press and you find that your shoulder gives out sooner than your chest, you would want to employ some shoulder exercises to help out.

Yup see this is exactly what I was worried about. Luckily I don't think the website is making claims anywhere for what its purpose is, I just wish it'd explicitly say somewhere "yo if you're a noob, this is not the place to come to learn how to build a workout plan. It's an index and reference for once you've already put exercises on a plan."

In regards to your "why," it's a pretty broad question to answer. Why should you do weight training? It's good for your health, usually, ask your doctor for if that's true for you specifically (usually the answer is yes). As in, studies show health benefits unrelated to the actual benefits of bigger muscles and greater strength:

1. Improves heart health 1, 2, 3, 4 (sorry too lazy to properly format cites)

2. Lowers risk of diabetes, good for managing blood sugar 5 6 7 8

3. Positive psychological effects (outside of just feeling better about your appearance, it literally affects your brain chemistry) 9 10 11 12

Consider also some of the more "common sense" or "obvious" side effects of simply being stronger: reduces your risk of injury, increases your bone strength, boosts your self esteem (even if your culture doesn't value macho muscly people, simply being stronger can be a self esteem boost), and, being stronger is just kinda fun and nice and convenient. Consider: one trip from car to the house with grocery bags, or, picking up your dog / kid / friends more easily. Even when I reach up for a big bag of flour and feel my muscles at work, I find some amount of satisfaction.

If you mean "why should I work a certain muscle group," the answers are all over the place, and really situational. Someone might be working a specific muscle group because of an injury and are doing restrengthening or creating greater strength in a way to prevent future injury, or, because they need a rebalancing for compound exercises (i.e. their abdominal strength is a blocker for greater deadlift weight), or, aesthetics (bicep curls, all day, every day, or, the more modern variation: waaaay too many squats).

If you're "someone who knows almost nothing about muscle building," and are also interested in it, I recommend a workout plan that involves compound exercises. Start with your why so you have a goal in mind to drive you, i.e., I wanna be able to carry my kid for longer, I want to increase my quality of life, I want to appear more aesthetic, I want to feel more confident when hiking with weight, whatever, pick something. Then, consider your equipment situation: do you have access to a gym and the time to go there? If so, barbell compound exercises are worth investigating. If not, bodyweight exercises (these are great to do with barbell exercises if you have the time, I really think everyone should be doing at least a little bit of bodyweight exercises every few days).

From there hit the forums:

If you're looking for something to do literally right now, and you haven't had a doctor advise against physical exercises for whatever reason, I guess get on the ground next to your chair and see how many pushups you can do? Here, the muscle wiki is useful for this: https://musclewiki.com/bodyweight/male/chest/push-up though it might help to watch a youtube video as well, I really love the "Hybrid Calisthenics" channel https://www.youtube.com/watch?v=0GsVJsS6474 if you can't do a "full plank pushup" they have a good pushup "ramp up" method.

>why would I want to work specific muscles

As a beginner, you would not. You want to work the whole system, and to do that, you only need a handful of compound movements: squat, deadlift, and overhead press.

Once you slow down in progress on these bigger compounds, that's when you would want to start doing more targeted or more specific assistance exercises, in addition to the compounds.

Starting Strength is a good enough book to learn this stuff. Read it and beware advice on the subject of fitness, for every nerd, bro, and their brother gets a kick out of speaking with authority on this stuff, even if they don't know what they're talking about - just go straight to a reliable source: Starting Strength. It's become a meme, but it's good enough.

How about bench press?

You could do bench press instead of overhead press. They have a fair amount of overlap. Some beginning strength programs alternate between them.

Please don't spread out incorrect fitness advice, as it can lead to injury.

Disclaimer: I'm not a fitness expert either, just train regularly. So, verify anything I (or anyone else) tells you.

They work different muscles.

OHP/MP mainly works the delt, while the BP targets vrious parts of the pecs (depending on incline). Also grip width can change the balance between triceps/pec activation during BP

Recreational power-lifter here.

OHP gains certainly do carry over to bench press though. You can treat bench press as a "heavy" day lift and then use overhead press as a lighter pressing variation (but still go heavy) because there's enough overlap that it'll help your bench but different enough to where going heavy on overhead doesn't impact your bench press recovery.

Example:

Monday: 5 sets 5 reps of bench press.

Wednesday: 3 sets 5 reps of overhead press.

Friday: 1 set 5 reps bench press (trying to get as many reps as you can with good form, and increase the weight for next week depending on how many reps you went past 5)

Another way I've seen it done is something like this A B style workout:

Week A:

Monday - bench Wednesday - OHP Friday - bench

Week B:

Monday - OHP Wednesday - bench Friday - OHP

One really good source of info for powerlfiting / strength programming on youtube is Alex Bromely

Bench is great. Probably best not to do it the same day as overhead.

My program is structured around the compound movements forming the Cartesian product of {horizontal, vertical, leg} × {push, pull}; bench press is a horizontal push in this arena. Overhead press would be a vertical push, and squat would be a leg push.

You might not want to work specific muscles. But if you did, it could be for as basic a reason as vanity or just thinking having large delts or biceps is "cool". Mike Israetel has a good video on the general principles that go into specialization: https://youtu.be/BsuI-E_iIWc However, if you're a beginner, you should not specialize, in my opinion. Being completely untrained, strength and hypertrophy gains are so easy to come by — you can progress linearly for quite some time before reaching even an intermediate level. You would want to focus on big, compound movements which involve muscle groups and then potentially layer on top of that some isolation movements (usually at higher reps, possibly more sets), purely for hypertrophy. The truth is, though, that even the compound movements do target muscle groups though(groups, not a single muscle), e.g. a bench press will work pecs, delts, triceps and others, whereas the pecs are minimally involved in deadlifting and, instead, they work the glutes, quads, the posterior chain generally, etc.

I'm rambling a bit, but the point is that compound movements are so effective and they're really the most efficient way to drive strength and hypertrophy gains, especially as a noob, that it wouldn't make sense to do a ton of isolation movements. And even if you did do a bunch of isolation (as opposed to compound lifts), it wouldn't make sense to just pick one muscle while minimizing others while you're still building up a base of strength and physique.

I have two exercises I do that target specific muscles. I've added them to my regular routine as I find they're a weak point in my overall strength. One helps fight a back injury from a car accident, the other helps stability when trail running. Neither muscles get used enough in anything else I do to really develop, but their lack of strength can occasionally be an issue for me. I've found it beneficial. To be clear, I'm by no means ripped, just trying to be more active.

Broadly speaking:

1. Aesthetics - you want to change some part of your physique by targeting certain muscles. Think doing curls for bigger biceps.

2. Performance - you want to get stronger/improve mobility by targeting muscles or groups of muscles associated with a movement. Think doing hamstring curls to improve one's vertical jump or deadlift.

3. Therapeutic - you want to gain/regain/prevent the loss of capability. Something like deadlifts for back pain and posture or band pull aparts for shoulder pain.

More specifically:

Most strength and bodybuilding programs follow a template where each session has a main compound movement followed by accessory movements that target a handful of different muscles, usually split by upper/lower body or by type of movement (pushing/pulling) with the intent of working most of your muscles. Many non-compound movements for any given muscle are more or less interchangeable if you want variety in your program, have something that prevents you from doing a particular movement or just don't have access to the required equipment.

For instance, overhead dumbbell tricep extensions give me elbow pain, so I do cable tricep extensions or skullcrushers if I don't have access to a cable machine.

I’m formally trained in this subject and I find parts of replies to you as correct, while most are just outrageous.

First, you should define your goal. Do you want to be generally fit, or do you just want larger biceps? Can’t force you to be well-rounded and ask you to change your perception of beauty, so if you just wanted bigger biceps then go ahead and just do curls. Be warned though: other fit people are going to notice the imbalance in your body such as skinny legs, underdeveloped forearms, bad upper body posture, etcetera; and even your perception of beauty will change as you progress, so I strongly suggest that you do not train for just one muscle.

If you go for general fitness, start with the most basic compound lifts: barbell bench presses, either squat or deadlift, and then barbell rows (funny how no one mentioned this exercise, lol). These are the most essential movements involving the largest and most essential muscle groups that are used in any other exercise. And note how I speak of muscle groups — in order to perform a muscle contraction, you’re actually not just using a single muscle. You have prime mover muscles, and others are stabilizers, and you want to train the whole group by doing exercises in full-range of motion so that they are all developed, because that will keep you safe from injury when doing more challenging exercises with them.

If you want to know more about the whys, the subject that you want to study is called exercise physiology.

There can be certain beneficial imbalances for particular sports. Rock climbers tend to need disproportionately strong fingers, and legs focused for jumping rather than pure strength. Boulderers need more focus on legs than route climbers, mountaineers need more overall balance and endurance, etc. Too much imbalance can lead to injury (all lats no pecs would be likely to cause back pain, as would the reverse) but some can be useful for particular goals.

I disagree with the notion of “beneficial imbalance” here. It’s likely that we may be thinking of the same thing when I’m talking about “optimizing or specializing for a sport”, but I will never use my notion as an argument against training the essentials. You‘re not going to be a more successful (and more importantly, _safe_) rock climber, boulderer, or mountaineer without a baseline strength in the essential muscle groups because those will keep your whole body stable and your posture as it should be while you’re wiggling your body about vertical surfaces. Well-rounded baseline strength could very well spell the difference between life and death especially for the activities that you mentioned.

There’s also the fact that should rock climbers, boulderers, and mountaineers have lives and real jobs outside what they do for recreation, then the reality is that they have a variety of bodily movements that just need to be generally done with, again, good posture, which you simply can’t have with an imbalance in the essentials.

We are building some tools around our exercise library. One being a "workout generator" you tell us what equipment you have, what your goals are and we'll generate one for you.

Edit, this is my website.

You might have muscles that are poorly developed and imbalanced which lead to poor posture. An example common to people who have desk jobs would be your back muscles like traps and lats. Even just simple exercises of these muscles can greatly reduce the ‘slouched forward’ posture

In terms of athletic performance, often athletes work specific muscles or muscle groups to improve ability at the margin(e.g. a higher jump or more powerful kick) or to lower the risk of injury from sudden, unpredictable movements(wrestlers have powerful necks in part because neck injuries are career-enders). A general, untargeted approach like "carry a young calf around the stadium" (the approach claimed to be used by ancient wrestler Milo of Croton) also builds strength, but more in a sense of overall athleticism, which is generally good for health but doesn't necessarily optimize towards a specific activity: e.g. the possibility of becoming "too big" presents itself wherever you're relying on a blend of speed, strength, and stamina. Strongmen competitors are very strong, but they don't have as much stamina or speed as people who trained to be strong at a lower weight.

For many people, it's aesthetically driven: bodybuilding is a form of beauty contest where a certain kind of muscle development and leanness is considered ideal, depending on the specific contest you're entering. And so you train and diet accordingly: gaining mass in areas that need to be brought up, trying to even out two sides where their size differs, dieting down to show more of the anatomy. Even if you aren't aiming to enter shows, many people will use these parameters as an aesthetic target.

If you're in it for general health, the distinctions are interesting trivia, but you're basically served by doing exercises that are known to train all parts of the body. Combat sports offer a good model for this kind of training since they demand an overall balance of athleticism, and to eliminate exploitable weaknesses.

https://exrx.net/ is generally the go-to.

looks very messy though I understand its 90s style website.

This. It’s built by a bodybuilder and not a techie and that shows, but it’s entirely serviceable.

Ryan (the founder of MuscleWiki) used to be a body builder. Iirc, he's also an accredited personal trainer.

I really like some of the accessibility and usability features here, like having a "copy" button right next to the exercise!

I'm confused why it's called a "wiki" though, I didn't see how to contribute? Was that just a funsies name? Wiki to me means something that's editable by the community.

I'm also not quite sure the audience here, because it seems to indicate "find exercise by muscle group" to be the way to use the site, but that's not really... useful... to people that don't know proper form for some of these basic exercises. If I view the site like this: https://musclewiki.com/directory then it makes sense, like, ok, I set up a training regime for myself, or I'm looking at the one set up for me by my trainer, and I forgot cues and good form for a given exercise, lemme just look it up real quick in this really light weight, functional website. Boom, GIF, cues as bullet points, done. That is a great use case.

What I'm worried about is a noob will come here, hit "biceps," then have a workout day of five kinds of curls. Which I guess to many is obvious why this is bad but just in case: broad strokes, if you're lifting, especially as a noob, it's better for your health, strength, and long term safety to be doing workouts that work your entire system, rather than "targeted" exercises only, such as curls. A good noob exercise plan is some combination of barbell squats, deadlifts, bench press, rows, and overhead press, or for bodyweight, pushups, dips, pullups, and squats.

If said newbie only wants bigger biceps then training only biceps isn’t a bad plan.

Maybe... I would hate for it to lead to more rounded back because they didn't do exercises to create requisite support in their back. If they can maintain good posture while doing curls it's probably fine.

Having some balance between a joint's flexors and extensors is a good idea, fair enough. I've never heard of too much curling precipitating a rounded back. Even training everyday you're not going to be hunched over for that long.

We are building out a bunch of tools around the exercises. One is a "favorites/playlist" type feature. I think that's near "copy" you mentioned.

Again, this will come with tools. I built the original concept for the site out of frustration around SEO, and the general people taking for 10mins and not getting to the point. However, I see your point and as I mentioned above, we are working on more guided features and building search into the site to get people to the content faster.

The site started built on wikimedia but didn't blend well with clean ascetic, but that's pretty much the reason for the name and it stuck. I think one day we might build wiki like functions into.

Working specific muscles is a terrible idea for the typical person looking to improve general fitness. The major compound movements are almost always what you want: barbell squats, overhead press, bench press, deadlifts, barbell rows, chin/pull ups, and dips[1]. Those will fix your posture problems among other things. From there you can work your way up to showing off on rings, glute ham raises, standing back bends, and even a planche progression if you really want to break the ice at parties.

I mean sure, if you’ve got the genetic gifts, the drive, eight hours a day to spend in the gym, and probably the gear to be the next Mr Olympia and you just need some hypertrophy on those posterior delts to put you over the edge then by all means target specific tiny muscle groups.

On the other hand if you just want the usable strength to handle life’s unexpected challenges then compounds all the way.

Edit: If you're a true beginner, get a good coach. Frankly I think beginners would be better served by a site on how to identify a good coach than one on how to do the movements.

[1] If you're a beginner you likely won't be able to do pull ups or dips unassisted, so either find a gym that has a machine that can give you assist, or use rubber bands. In fact if you're truly out of shape you might not even be able to do a proper bodyweight squat. If so, no problem, you can either assist by using rings, or progress with a leg press machine.

This site is about finding specific exercises for specific muscles though, and I think it works really well for that, I’ve used it off and on for years.

There are plenty of reasons an individual may be looking for exercises to hit a specific muscle. I agree compound lifts are great for people interested in pursuing general fitness but there are plenty of people who can benefit from this.

I’ve used it because I needed to strengthen specific muscles after injuries or to protect from re-injury and wanted to explore options. I’ve also used it to mix up lifting routines by having multiple exercises I can rotate through that hit the same muscles. Clearly I’m a fan :)

Just like being in the gym, it’s important not to judge how others are working on their bodies^. You never know the story behind why someone is doing what they do.

^unless they’re putting themselves in honest to god danger of course!

Agreed. And from looking at it this seems to be a very good site. For example the bench press page[1] includes some very important tips on a wildly popular movement that will help people avoid rotator cuff injuries.

And of course I agree that you shouldn't give a specific person unsolicited advice unless they are clearly endangering themselves. But this is a general discussion site, and generally speaking I'm going to stand by the claim that most people should focus on compound movements and not isolated ones. And this looks to be a good site for information on those, so that's great.

In fact, this site appears to be less focused on specific isolated movements than exrx.net. For example I didn't find anything nearly as specific as, to give just one example, the dumbell rear lateral raise[2]. Incidentally, that's a remarkable movement on account of even monstrously strong men have to use relatively light weights to perform it properly.

I remember using exrx a decade ago to build a workout routine with dumbbells that hit all muscles. Such an excellent resource.

Any source that strength training "improves" posture? I don't believe there's even an accepted definition of what "good posture" is supposed to be.

I hear this touted often and have never read of clinical data that would support the idea that "muscle imbalances" are a thing and cause of perceived undesirable body position.

I see a lot of recommendations in this thread already, but any specific suggestions for a beginner whole body routine using bodyweight/dumbbells that also can help with stretching/flexibility?

Edit: And also free. Not that I am opposed to people getting paid for putting out quality health education content - but free is preferable.

I just started gmb.io they have several programs similar to this

+1 for gmb.io - it's the only program(s) that i ever paid for - they are that clever. (i am athletic, walk my dog daily, have access to crossfit gyms etc). gmb.io "fills the gaps" of daily movement deficits and is for everyone.

How do you track your reps and weight per exercise? My trainer wants me to use paper. There are too many apps for this, and most of them are adware or junk. A glorified spreadsheet is what I’m looking for (mobile).

if you start tracking reps and weight, i guarantee you will loose interest fast. while tracking might certainly be useful for muscle building, gmb.io has a different approach and focuses on movements that are safe and help you in real life (mobilise wrist / shoulders, prevent back pain improve posture etc). A lot can be done without fancy equipment.

I’ll try gmb.io. It looks great.

But when I go to the gym once per week, and do 10 different exercises with weights or machines, I want to know what weight I used last time so I can start there (or just above it) again. Maybe you have the memory of an elephant.

Or Maybe you don’t care if you spend 2 minutes at every machine first figuring out what weight feels like just enough, not too much or too little, before doing 3 sets? Enjoy that. But I don’t want to do that. Every. Single. Time i go to the gym. And there’s no way to see my progress?

Not the parent, but I don’t think they are arguing against tracking weights when weight lifting so much as they are arguing against “traditional” weight lifting routines in general.

I have not tried gmb.io, but looks like progression in that program involves moving onto more difficult movements rather than increasing weight.

You'll remember the numbers after the first 2-3 gym sessions without any kind of apps or paper tracking. It's not a problem at all.

I speak this as someone who has terrible memory.

An app called Fitnotes, which I've used for years, is a glorified spreadsheet in my opinion.

Also contrary to another poster who insists on not tracking your lifts, I find it essential both for making progress and maintaining interest, its somewhat comparable to levelling an RPG character. At the very least its useful for remembering what you've done recently so you know what to do next.

"insist" is a bit harsh; we're all trying to help here ;-) https://xkcd.com/386/

+1 for fitnotes, probably the best app out there for my needs. Very flexible, gets out of the way, and has some basic analytics like plotting graphs and calculating one rep max values (which I never use). The graphs I find very useful to see if how I'm trending over many months.

Confusingly the iOS App Store has FitNotes and FitNotes 2. Different authors. I’m guessing the latter hijacked the name?

I only know it on Android, looking at the iOS App Store it seems like they both hijacked the name from Android, yet that FitNotes 2 is marketed as a clone of the Android app. The other FitNotes in iOS looks totally different in function/UI

I use Stacked. But only because I enjoyed books & content written by the creator. It's not as easy to adjust as other apps, but it's totally free and I think it's visually pleasing.

I appreciate the suggestion of gmb.io from you and the parent. I had something more traditional in mind when I asked for suggestions (pushups, situps, squats, etc.) - but the intro on their website is intriguing enough that I think I will at least give the free session a try.

Reddit fitness subs have a surprising amount of information in their wiki(s)

https://www.reddit.com/r/bodyweightfitness/wiki/kb/recommend...

I was hoping this would be a lot more targeted. What if I want to focus on my rear delts? Subscapularis? Serratus anterior? Yes, I have bad posture.

An "advanced" bodymap is coming soon. We are just figuring out the best way to do it on mobile.

Been lifting for 5 years now, going to use this site it's great nice work!

For anyone that just wants a well-balanced workout plan I highly suggest checking out this guide: https://www.julian.com/guide/muscle/intro

I’ve used https://exrx.net/Lists/Directory for years. I find it the most comprehensive directory for exercises on the internet.

As someone who has been working out for a year this is great. I still don't know all the muscle names and I am still exploring and finding exercises that work for me.

Discussed last year too (329 comments)

https://news.ycombinator.com/item?id=25854523

Would be nice if for muscles where there are multiple excercises listed, if it would also state what are the functional differences between them.

Would be awesome if you included stretches as well, like yoga-esque postures

we have stretches. https://musclewiki.com/stretches/

However, we are filming Yoga on Thursday this week.

SS + GOMAD

Simplistic and probably bad advice unless you want to prioritize strength over everything else and can't gain weight otherwise.

Grandparent likely means Super Squats, not Starting Strength, which is definitely a bodybuilding program.

Still hard to top exrx.
