Drawing Muscles: What You Need to Know

Drawing Muscles: What You Need to Know


Intro to Drawing Muscles Hello, welcome to Proko! My name is Stan Prokopenko.
We’re finally at the part of the course you’ve all been waiting for. Muscles! In
this video, we’ll go over what you need to learn for each muscle, some general muscle
anatomy, and the types of muscles. Need-to-Know! or Should Know There’s a basic checklist of things we will
learn about each muscle. This includes the muscle name, origin, insertion, function,
antagonist, and form. The name of the muscle is the least important
thing to know about the muscle. Many artists you ask will say you don’t need to know
the names at all. That’s partially true. It depends on how deep you want to learn anatomy.
I got away without knowing the muscles until I started teaching it. But, knowing the name does have some benefits.
Knowing the muscle name allows us to talk about anatomy. I’ll give you tricks to help
remember muscle names whenever I can. There’s usually some logic to the name that hints
at the muscle’s location, function, or form. For example, the “Extensor digitorum muscle.”
This is the muscle in your hand that extends, or straightens, your digits. Where the muscle attaches is important to
know as well. It helps us precisely and confidently map out the muscle. It also hints at the muscle’s
function, as we’ll see in a minute. There’s two areas of attachment. The Origin is the
attachment on the skeleton that is more stationary and closer to the center. The Insertion is
the attachment on the farther and more moveable part of the body. You should also know the function, or what
action each muscle is responsible for. Fortunately, functions are pretty easy, because muscles
can only do one thing… Contract. When you flex a muscle, it contracts, and pulls the
insertion closer to the origin. muscles work in pairs. When one muscle contracts,
its antagonist is stretched out. The bicep flexes the arm and the tricep extends the
arm. In your drawings, try to exaggerate the hardness of the active muscle, and let the
relaxed muscle conform to gravity. Being aware of the muscle’s function is essential for
invented poses, so you know which muscles to flex and which to relax. It gets you away
from drawing a “noun” and back to drawing a “verb,” and your poses will have greater
animation and impact because of it. If you want to draw constipated superheros, then
you can ignore what I just said. A muscle’s name, attachments, and function
can be summed up with just a few words. We’re artists. What we really need to study is the
Shape and Form of the muscles. We have to understand the muscle in three dimensions,
so we can draw its shape from all angles. This includes variations like stretched, relaxed,
or flexed, and different body types. We’ll study the plane changes, the simplified forms,
and other detailed awesomeness about the forms. It will help you invent figures from your
imagination and make them anatomically accurate and dynamic. Types of muscle… available in the premium
section. If you’d like to learn about the 8 types of muscles found throughout the body,

  1. En realidad nunca pensé que estudiar como funcionan los músculos fuera tan relevante. Viendo el asunto de antagonista la verdad ayuda bastante.

  2. the lack of muscle skully in the skully app its whats keeping me from buying it! Please add muscle skully! Ive been wanting to buy the app since forever!

  3. Только недавно стал вашим зрителем и сразу подписчиком. Спасибо за видео…

  4. Do we ever get to go over the changes in bone & muscle structures as models age from young to old? I struggle with how to design younger, athletic characters without giving them mature physiques or older, more experienced characters without giving them a youthful physique.

  5. I don't like to unnecessarily bother my friends with information they didn't ask for.  Don't you be greedy and assume I need to share.

  6. To learn the names of muscles and even basic terms I would recommend using this website: http://www.memrise.com/course/87415/artistic-anatomy/

    It is fun to learn and easy way to remember all those names! 🙂 It's kinda like a little challenge too when you do it with friends (who has the higher ranks, because you get points from learning)

    I hope that helps! 🙂

  7. It's fun, cause I learned anatomy in comic books, now I see this videos and all the complexity of the shapes, bones and all stuff. I guess is the line that separate the pros of the amateurs!

  8. I don't understand why people would want to put all the effort into learning anatomy and not go the extra couple of meters to learn the names. Knowledge that exists in your head without the ability to communicate it is worth far less than knowledge you can share and vocalize.

  9. Great lessons all the way!
    But your skeleton animations make me sick! 🙂
    Please stop doing them.
    They're disturbing on so many levels. (

  10. I actually sat yesterday in my studio and just watched many of your drawing tutorials, you're a very talented and skillful artist,thank you very much proko.

  11. I love you, I love your videos. and you're really great man! you make learning fun, so unfortunate I cant get to meet you

  12. Proko, I don't know if you can (like advertisment issues or such, I don't know! )
    But could you make a video in which you show ALL the books you've found more useful and such?
    I know we all have to make our research and we totally do (at least I do) but would be so cool to get an insight on those shelves you have in the beginning of the video ))
    Thanks! Bye!

  13. @Proko: I think you never actually talked about the coracobrachialis, although this muscle can be seen on the surface. I think it is weird that you haven't mentioned it yet.

  14. Maximum of your lessons is in your patreon page, which is very expensive. It may be useful to Americans but not Indians.

  15. dude you look like Professor Moriarty and Christopher nolan combined lol , these tutorials are great btw 😀 thanks for the info

  16. Dear Proko,
    please relax your neck.
    You've been raising the chin, showing the nostrils and eyeing down on the camera all the time.
    It looks neck tiring. Please let your face perpendicular to the ground.

  17. I love Skelly'
     application is very transparent and uses it well. Question to Stan Prokopenko – is it possible to expand the application for adding muscle? As I see the Skelly animations on YouTube has rigged some parts of the discussed muscles. I create 3D models and rigigate. From a technical point, I know that it is possible. It would be great to combine: "Muscle | Skeleton – 3D Atlas of Anatomy" or "3D Anatomy for the Artist" together with "Skelly". Do you consider this?

  18. I've been noticing things that I have never noticed before after following some of your videos. Muscles in the back and neck, and in the legs as well. I'm still a novice with drawing, but I look forward to eventually buying your course (when my schooling is done in five months)

  19. For all my people struggling out there the three main types(really the only types) of muscles are
    cardiac muscle (heart)
    skeletal muscle,is a type muscle that attaches to your bone (biceps,deltoids,quadriceps)
    smooth muscle, (usually just your digestive system like esophagus )
    idk about 8 muscles but i know they are three (unless he meant antagonist and protagonist but that just makes it five it's not even considered a type of muscle but whatever),guys don't waste your money and do your research or go to fitness channels like Athlean x to learn about muscles FOR FREE
