How to Draw Triceps - Arm Anatomy for Artists

[@PikaPetey]

OH MY GOD YOU ACTUALLY PUT MORE PIKACHUS INTO YOUR VIDEO! XD!!

[@cudamalloc9054]

Ayyyyyyyy lmao (supbruhloveyouranimationsienvyyourskill)

[@xadek821]

This one was the hardest so far to imagine in your head, but after watching it like 4 times and doing just 2 assignments it became very clear. Love the fun explanations with bears, because for some reason the human brain loves to remember silly things. Thank you for the video

[@TehDanceMaster]

I'd like to see stuff about origin and insertion points, and how to identify the masses on a thinner figure.

[@kidnamedfinger9736]

Yes that makes it so easier

[@catlookingdownonyou5465]

Maybe the in depth version is in premium

[@roquesanchez9814]

It’s the same thing. The masses are just smaller. Treat them like balloons and just deflate it. All anatomy is the (generally) same in humans. insertion points and all.

[@chikengas4052]

@@roquesanchez9814 exactly.

[@alharris1428]

Concerning the forearms, I'd like to know how the muscles are shaped, origins and insertions and how they change due to the movement of the radius. Love you Proko thanks.

[@000bullets]

Al Harris to add to that, I would like to know which ones are essential to draw, for example most of the flexor side isn't visible as separate muscles like the extensor side, and not every muscle is visible on the extensor side either.

[@tdsuperman]

... with particular attention to how the muscle forms change with different arm movements and angles.

[@roquesanchez9814]

If you take the time to study anatomy it’ll open the door everything you’d like to know about shape, origin and insertions. Go and actually look and draw draw draw draw. You’ll learn it a lot faster than watching a proko video.

[@svogunelis5]

If i can be of any help : For the forearm that has so many muscles, we really need to distinguish these muscles and the forearm's global shape. Then how they change with different hand positions. Finally i still find the bottom part of the arm a bit confusing. Thanks

[@brotherfullmer]

I agree with everyone's thoughts but most of all I want to understand the big forms like Trukas said. I find these the most difficult shapes to understand on the arm - especially the group around the brachioradialis

[@fanartfanatic4345]

i agree 100%

[@adamodimattia]

As others have already mention this somewhat, my biggest and seems eternal problem with the forearm is its changing shape during pronation-supination transition, how the flexors and extensors change their direction, especially when trying to make a more detailed anatomical drawing of the forearm. I'm sure you can come up with some witty indicative of how to manage it as you always do. Thank you Proko for great material, great lessons, although I know my anatomy pretty well you help me fix this stuff even better in mind. I am not a premium member but sometimes I buy stuff from your site ;) Cheers!

[@Uhcip]

was not expecting chuverine

[@Cinocephalus]

About your next video of the forearm, I myself don't need asking for something in particular, but as an artist myself who studied anatomy in university I could recomend for people learning now to make special considerations on the overlaping if the different layers of muscles in the forearm, which makes it much more complex than the upper arm. It helps to distingish between inner muscle layers and visible ones. Keep your good videos.

[@itayshlomi2722]

Realy looking forward to the forearm video

[@ivan-levpolezhaev9418]

hey, proko! regarding forearms, I'd love to know how it varies, maybe some exceptions and more more more examples. how the shape of it changes in 3d when radius is rotating and when there is a real tension in hand caused by squeezing smth (or a fist). how bending of separate fingers affects the surface of a forearm.

Oh I really need this! Thanks proko!

[@sachinchauhan3244]

Great Help!! Thanks a lot proko

[@mat-andre]

I'd love to learn how the muscles look and react particularly when the forearm is twisted, and how to subtly represent the muscles under the flesh. And any major arteries or details that show in particularly defined arms. As a fantasy/comic artist, these vein-popping details add awesomness, but are difficult to know where to place. Thanks @Proko for all you do!

[@borisp9163]

Man you have best videos in muscle anatomy 👍🏻

[@aimeefritz9186]

I would like to learn in the next lesson how the flexor and extensor muscle groups appear in back view. I struggle with how those groups appear when the arm pronates and supinates from the back as well as the sides! I know the extensor groups are supposed to follow the the thumb but I just can't visualize very well when the groups seen from the back. Thank you so much as always for the lessons! :)

[@RokasDesigns]

that was an awesome, very comprehensible tutorial! I think a similar format for the forearm tutorial would be helpful with some explanations of how the muscles correspond to the rotation of the radius. At least that's what I'm having a hard time with.

[@HeroG9000]

Art is a wonderful thing

[@silvajoao142]

biggest trouble about forearms is finding exactly where the three main shapes origin in the upper arm and insert at the wrist. can become very confusing and frustrating to study just from looking at different models (because they simply are different). but, then again, i figure that's what your video is going to cover

[@starloose9467]

Thx Proko :) About the forearms, i'd say that your usual format is great but I think you ask us because the forearms have maaaaaaany muscles and a lot of twisted shapes and you might wonder what is the best way to cover it so we understand as many things as possible. So I would say that the most important point is to being able to recognize the muscles. They are many ! Don't hesitate to show them to us on model photos :) several times ! And I think the second most important point is to know how to regroup them as best as possible. So tell us which ones can be drawn to a single (more or less) and simple (more or less) shape :) I get confused with this part of anatomy although I do know what are ALL the muscles sitting there ^^ Give us your tips to recognize them, place them, simplify them and design them :) You do this pretty well since the very beginning of your anatomy videos :) also, your "anatomy part" where you tell us what they do and why they are where they are is very cool and pedagogic. Personally it helps me to remind what was unique about this one or another and recognize it easier. May be you'd consider treating them in several parts. "Supinators-pronators" or "biggest shapes-smaller shapes" or even by "groups" like "at each muscles that can be gathered and simplified together in a single shape their own video" :) Might be less exhausted for you because treating all at once could be very difficult. It would also allow us to digest all the infos step by step rather than opening our mouth as big as possible and eating it all at once, missing important stuff.. Anyway, I trust you and I'm sure you will find a great way to tell us the "mysteries of the forearm" ahah. Can't wait for it. The arm in general has been the part I was the most waiting for you to treat ! It's more complexe that it seems ! Happy New Year btw :)

[@3DARTNOTES]

Please show how the brachioradialis changes shape when the arm is in different poses

[@ericpeterson535]

If im honest what I would like to see after you're done with the muscles in the arms is to perhaps draw them in different posses and perspectives.

[@uberrave3]

Plz do a lesson on the flexor and extensor digitorum.

[@TASmith10]

I agree with the other posters, but I'd like to add the importance of video that shows how the muscles work and flex to control the fingers - and also muscle groups, how to categorize muscles by function so you can group them together and simplify them. Possibly you could do two videos for the anterior and posterior sides of the forearm - if that's useful? I hope in the premium version you cover every muscle and its function, because I plan to buy that eventually - I like to wait until the series is complete :)

[@seanleebush]

I would say it is important to learn what effect the movement of the hand has on the over all form of the forearm. That would be the biggest thing I really want to learn. Also the anatomy of course, but you do that really well already. I like the more dynamic elements you are adding into the videos. Keep up the good work Stan. I love your stuff.

[@cgooch_]

Forearm Lesson :: How the muscles in the forearm appear when contracted and extended in various poses, to include: 1. Varying finger gestures, such as having one or two individual fingers flexed and extended - the muscles that contract in response to those fingers and how they appear. 2. Contracted hand/fist positions and how the muscles and bones appear when flexed this way. 3. All of the above with the wrist/hand twisted in various positions and postures.

Hi Stan ! How about making a forearm muscles video on the extensors muscles an the bigger one that overlaps them? The one starting from between the brachialis and the triceps Those are the ones I think are the most important ones when we wanna draw the superficial forearm muscles. Thanks ! We all love your courses !

[@gabrielveras123]

About the forearms: 1) The muscle that bulges up when you fully pronate your hand and contract your bicep, near the elbow. I'd like to hear about it's origin and insertion. 2) Vascularity. I know that this is technically not muscular anatomy, but it seems very relevant to me when drawing this particular body part. When drawing a realistic figure, or an actual portrait, if the model has an athletic body type, there will usually be some tricky subtle veins to render. 3) Hair. Also not muscular anatomy, but... most dudes have some hair on their forearms. Hope at least one of these is mentioned! Thanks Proko, u da best.

[@xiaa]

Maybe physique variation for arms. Or maybe a how to draw hugs video for Valentine's Day.

[@athompsonian]

Hardest things with forearms? The furrows and depressions around the elbow, AND how the muscles can send the gesture line shooting off somewhere it doesn't belong.

[@cl0udbusting]

Studying the arm from Burne Hogarths book but having trouble trying to synchronise what I know with other sources. Some info on (1)what muscles supinate and what pronate - not sure if flexors and extensors play a part. (2)abduction and adduction muscles? (3) order of muscle overlapping ... Sources differ on what muscles overlap what. Love your vids 😊

[@kris-chan1440]

Forearm.. the connections to the wrist

[@mrsplosh999]

Its kinda insane when you realise that the tricep and connections are so similar to rhe calf muscles. I found it so hard visualising the medial head. However the calf helped bridge that gap :).

[@azharnasar493]

I'd read about the extensors and flexors of the forarms, their corresponding origins and insertion points, their function and forms, from some of my favorite anatomy books. But I'm confused about their visual hierarchy and how to make them concise, simple and manageable to draw. I hope your videos will address my worries

[@raposaox]

Excellent !

[@DaveBarrack]

On the forearms, I tend to overemphasize the Brachioradialis/Extensor Carpi Radialis Longus. I think that's because it's the only muscle that can have any significant definition. The rest are just stripey things running the length of the arm. I mean, they're not, but it's always been good enough to fake them. I also get hung up on the B/ECRL when foreshortening an arm, probably because I overemphasize it too much in the first place.

[@humanityisfamily7581]

Hi Proko! Would like to know how the forearm muscles change as they contract and others relax in their different positions (e.g. with radius over the ulna, and forearm flexed with hand turned inward and then upward, then twisted back wth same positions), and if the specific muscles can be highlighted. The twisting motion of the radius and ulna and how the muscles are affected would really help me.

[@erics7801]

[@Lipschitzable]

For the forearms I think that it's width is tricky; large near the elbow and narrow near the wrist. It would be cool if you showed us if there is any tip to respect the dimensions. And thanks Stan, you're awesome !

[@kamiladamczyk2469]

Id like to see how bulk of the muscle changes when rotating forearm. how to get grasp at insertions and how to simplify forearm anatomy.

[@knifedrowns8272]

I am really interested in how the _shape of the forearm muscles changes when in motion_ [same for other muscles]. It would be great if you could address that topic more in future videos! And as always, thank you so much for the informative videos!!

[@aimeefritz9186]

Yes I agree! I would also like to see that topic addressed ^^^

[@atenakehnaton3965]

Please spend more time covering foreshortening. So for example in dynamic poses you when the arm is coming right at you, you could cover how to judge the muscle over laps, in particular at the joints. Thanks Proko. For the money you charged, I'm genuinely surprised by how much I am receiving. Are there any books you recommend to supplement your course?

[@PartyC4nnon]

perhaps it would be best to have multiple videos explaining the forearm? We can see how the flexors and extensors function or behave as a group when the arm twists, then explore the muscle groups in detail in other videos?

[@Hadoken.]

Forearm: Tho I don't struggle much with it anymore I would like to see the motion, deformation of mass and interaction of the branchioradialis with the branchialis, biceps, the elbow joint (how it slides over the humerus/ulna while they bend and twist) and mostly how it's thickness affects this interaction. To elaborate, most of the useful reference one can find is of massive forearms. This however makes it unclear how thick this muscle gets on all sides, thus making it confusing to predict how it will interact with the underlying bone and the surrounding muscles. I've deduced that this muscle is pretty slender and slim initially, and while it grows much, a lot of that mass (which also contributes to the intense line created that separates it from the flexors) is built externally (not on the internal side that can touch the biceps when curling) and due to it sort of riding the point where the radial bone meets the humerus bone, but this isn't easily understood on a thin model because the muscle is non-existent and the muscularity of a large model hides the bone evidence. I'd just like to see if my suspicions are correct.

man... I'm sorry to call you annoying, I really am... but you are also a great teacher. I hope this can come across as the compliment that I mean it to be.. There are other channels that I prefer, but you are just such a master and explain things so well. Thanks for your videos

[@runargisli9694]

I know how to draw the forearm in most poses but when it gets really twisted for an intense pose i just cant seem to get the anatomy right. I know where most of the muscles connect but something looks off.

[@dmitryrudenko4998]

man same with me , when you draw forearm don't forget about the twist. It looks off sometimes, cause we forget about "arm - elbow - wrist" twist, its all connected and have theirs limitations. For instance, you never noticed that when you twist your wrist, you biceps shortens?

[@allluckyseven]

Gee, these videos are getting crazier and crazier............. I love'm. But yeah, thanks, Stan. I always wanted to know what was that on the inside of the arm, under what it seemed to be the whole of the triceps. It's the baby bear, of course!

[@Stillenacht3D]

Regarding the forearm lesson, I usually get confused when it comes to the anconeus muscle. I understand the origin/insertion but when the elbow bends fully I'm often unsure what happens to it as the elbow becomes very square looking and I'm assuming that muscle has something to do with it. Thanks!

[@designingjuan]

For the forearm, I'd like to understand the range of motion and how it affects the muscles when in action, please.

[@Metal-Spark]

For the forearms I would love some tips on how to remember the general forms, the muscles of the forearm are pretty complicated and I tend to forget which way they all flow and where they all connect without reference. Some simplified forms so that I don't have to look at reference of each individual muscle and then work backwards would be great - I'd prefer having the simplified version committed to memory then only looking up reference where extra detail is required.

[@allluckyseven]

I struggle with the form of the brachioradiallis, extensor carpi and the extensor digitorum. Especially the part closest to the elbow. And would like to see the arm without the first two muscles I mentioned.

I still struggle with the correct rendering of the Brachioradialis and Extensor radialis longus and brevis when arm twists (just like the last image in the video)..since the latter two attach on the metacarpal bones 1 and 2 I really don't understand why they almost overlap and disappear when arm is supinated (even slightly) when their body shoud be visible on the arm considerig their insertion on the first half of the hand's dorsal side...
