How To Draw Guys A Butt
Cartoon legs is a complex endeavor. So why is this the Easy Step-past-Step guide to drawing legs? This guide will have yous through simplified skeletal and musculus anatomy of the legs with like shooting fish in a barrel to understand explanations and illustrations!
As with my previous drawing tutorials, we will pause down a complex task into a serial of smaller and simpler steps. We will get-go comprehend the shape of the leg and major landmarks, and then await at the skeletal construction, then the muscles, and finally volition go over drawing examples, pace-past-step.
Hither is a summary of the drawing procedure for cartoon legs:
Establish proportions and angles with skeletal guidelines, then work on identifying and drawing the rhythms of the shape, then fill up in the muscle groups, and finally rework the overall cartoon correcting for whatsoever errors.
In preparation for this guide, I created many leg drawings, three step-by-step examples are at the end of this guide. Here is what nosotros will cover:

1. How to Depict Legs – Full general shape of the leg
Before nosotros go over simplified beefcake of the leg, let's look at where nosotros want to end upwardly. Below are the musculus groups we will go over.
Note these are not all the muscles of the leg. I took measures to simplify anatomy and I edited out a lot of smaller muscle groups, to get us the minimum we demand to describe the legs.
Let's wait a fleck at what we demand to know about the shape of the legs:
A great leg drawing is greater than the sum of its parts, that is to say, – greater than just all the muscles slapped together.
The position of the legs can define a pose in figure cartoon. Allow this section serve as a reminder that afterward you larn all the muscles of the leg, when you draw, yous should practise not lose sight of the overall.
The shapes in your drawings of the legs should instantly read properly. If the shape does not read correctly, something went wrong along the fashion – fifty-fifty if you think the muscles are where they should be – I would go back and check.
With that said, permit'south go over important landmarks when cartoon the leg.
On the sketch above, (illustration on the far left) we come across that the calf muscle (gastrocnemius) is positioned higher on the outside and lower on the inside of the leg.
It is the opposite with the lateral (outside) and medial (inside) malleolus areas – the sections where tibia and fibula run into with the foot. In those areas, the outside is lower and the within of the leg has the bony flake higher.
On the analogy on the far right, nosotros can see I indicated the tibia (shin os). In fact, you lot tin can feel this bone right nether the skin on the front end-inner side of the leg equally information technology is mostly uncovered past muscle from the knee to the pes. Later in this tutorial, we will also cover the knee cap in more detail.
In the middle analogy above, the great trochanter is indicated – a section of the femur bone very important to drawing the leg as it will aid to properly situate the glutes and other muscles around information technology. We will as well cover information technology below.
On the left, y'all see how the sartorius muscle separates the adductors from the quad muscles of the leg, notice the alter in direction. Notice also that the sartorius appears over the adductors from the forepart. We will embrace the quads and the sartorius in the muscles department.
In the image on the correct, notice that there are numerous muscle groups that connect to the medial (inside) condyle of the tibia over the muscles of the calves.
All of these details are important to making your drawings of the legs more believable. At present, without further ado, allow'southward become over the skeletal structure of the leg.
ii. How to Draw Legs – Simplified skeletal structure of the leg
Legs function similar to arms, in that at that place is one large bone from the hip to the knee and 2 smaller ones from the knee to the human foot. Muscles of the leg (quads and hamstrings) also role similarly to triceps and biceps muscles of the arm.
The quads are similar the triceps muscles and help extend the limb, while hamstrings are like the biceps and assistance curve the limb.
For now, let'due south effort to get a general sense of the skeletal structure. Nosotros want to know the skeleton because in the side by side steps we will start studying and attaching muscles to this structure.
3. How to Draw Legs – Simplified muscle groups of the leg
Before we comprehend the quad and hamstring muscles. Hither is a simple anatomical tip about those muscles that should save us much fourth dimension:
All of the quad muscles take a mutual insertion betoken at the kneecap. And all the hamstring muscles accept a common origin point, at the ischium.
Yous should also know, that nosotros use the terms 'origin' and 'insertion' when discussing muscle anatomy for a reason. The terms define more just zipper points.
The origin portion of the musculus doesn't move during muscle contraction, while the insertion portion does movement. Usually, origin points are medial, or closer to the middle of the torso. Knowing the difference gives artists an advantage when creating anatomically correct drawings.
Quads (Quadriceps) and Sartorius
In that location are four muscles in the quads. We will await at three because the forth is found deep in the leg, non visible in the drawing of the figure.
The quad muscles extend the leg, similarly to how the triceps muscles extend the arm.
The origin of vastus lateralis is at the greater trochanter area (only below), at the front (anterior) surface.
The insertion of vastus lateralis is at the common quadriceps tendon enclosing the kneecap (patella). This insertion indicate is the same for the other two quadriceps muscles we will cover!
In fact, all of these quad muscles connect into a tendon that then moves down and connects at the kneecap.
Origin of vastus medialis is starting at the top of the femur and downwards along the medial department of the femur.
The insertion of vastus medialis is at the mutual quadriceps tendon enclosing the kneecap.
Some muscles originate in multiple places, similar this 1. Rectus femoris originates at anterior inferior iliac spine, and groove superior to the acetabulum. In the prototype to a higher place, it is simplified to connect just to the inductive inferior iliac spine which will work fine for our purpose of drawing the leg.
The all-time way to remember this origin (for simplified anatomical drawings) is to call up that information technology connects correct above the hip joint at the forepart.
The insertion of rectus femoris is at the common quadriceps tendon enclosing the kneecap (patella) but similar the other quadriceps muscles nosotros discussed.
What is really important for the quads group, is to keep in mind that the fullness of the rectus femoris is situated above the other two muscles surrounding it to the left and right – it is the higher sitting muscle on the leg, go on that in mind every bit you describe the leg from the front.
Now let's add together the sartorius muscle to quads group.
The sartorius muscle, separates the quads from the abductor muscles at the front of the leg.
Its origin is at the anterior superior iliac spine, and the insertion is at the meridian of the medial (inner) surface of the tibia bone. (It inserts at the top of the insertion of the semitendinosus muscle of the hamstring grouping – see below).
let's quickly recap what we learned so far, we have rectus femoris that sits on the front of the femur bone, vastus muscles on each side of it, and the sartorius musculus that nosotros just covered higher up.
IT ring
Before moving on to the muscles on the back of the leg, nosotros need to comprehend one more item, the It band.
The Information technology ring (iliotibial band) also known as the iliotibial tract, is a long piece of connective tissue, or fascia. The IT band stretches across vastus lateralis on the outside of the leg and helps to extend, housebreak, and rotate the hip.
It stretches from the tenser muscle (covered below) and inserts at the lateral (exterior) condyle (ending) of the tibia bone (shinbone).
The IT band is thin, and not easily visible, and it non visible in most stylized drawings of anatomy. However, it is often visible in old master drawings and in very detailed anatomical drawings in general.
I mention it here in case you find yourself wondering about actress definition on top of the vastus lateralis muscle (the section of the quads on the outside of the leg). Now you know what it is!
Hamstrings
Hamstrings are on the back of the leg. They part like the biceps musculus of the arm, when you bend your knee, hamstrings flex.
The origin of the semimembranosus is the same every bit the other major muscles of the hamstrings – at the ischium (the curved bone forming the base of each half of the pelvis).
The insertion of the semimembranosus is at the medial condyle of the tibia (a condyle is a rounded protuberance at the end of some bones, forming an joint with another bone).
The origin of biceps femoris is at the ischium (the curved bone forming the base of each half of the pelvis). This origin is the same for all three of the muscles nosotros will cover for the hamstrings, making this group easy to study for drawing.
The insertion of biceps femoris is on the lateral (outer) side of the head (acme) of the fibula.
The origin is at the ischium as with the other hamstring muscles we covered. The insertion of semitendinosus is at the medial surface of the superior shaft of the tibia (inner surface of the upper portion of tibia).
Let'due south quickly review what we have covered so far with the hamstring muscles. In that location are three we need to know, one – semimembranosus, sits underneath the other two – the semitendinosus and the biceps femoris.
Calves
The origin of the gastrocnemius muscles is at the posterior (dorsum) surfaces of femoral condyles. (then back sections of the bottom tip of the femur bone!).
Insertion is at the dorsum of the heel via the Achilles tendon. I won't discuss the anatomy of the human foot in this guide since we have enough to discuss with the legs. Yet, if you are curious about how to draw the foot, check out my tutorial here.
In the image below, permit's look at all the muscles we discussed and so far:
As you can see, I added three muscles in pink on top of the diagram in addition to what we have already covered. Two muscles of the glutes and the tensor, allow's discuss them now.
Glutes and Tensor
Tensor fasciae latae (Tensor)
The origin of the tensor is at aterior superior iliac spine and insertion at iliotibial tract – (Information technology BAND) that attaches to the lateral condyle of the tibia (retrieve nosotros covered the IT band in a higher place? aye, it is the same one).
This musculus latches on to the IT ring that moves all the way down to the tibia (right on meridian the vastus lateralis). The IT band is not shown higher up since it is thin and vastus lateralis is what volition show through most of the time.
While the tensor muscle seems pocket-sized, do not overlook it, it is one of those muscles that if omitted will provide for a leg cartoon that never looks correct.
Gluteus medius
The gluteus medius has an origin at the posterior section of the ilium (Gluteal surface of ilium ) with insertion at the lateral surface of the greater trochanter (femur).
Gluteus maximus
The gluteus maximus has an origin at sacrum and coccyx, and the gluteal surface of ilium with insertion at the Iliotibial tract (IT band), and gluteal tuberosity of the femur.
Adductors
There are multiple muscles at the adductor group, they generally originate from the pelvis and insert at various points at the femur. This muscle group helps bring the leg back towards the eye of the body.
Most are visible on the inside of the leg. As you meet in the diagram above, I am simplifying this entire section. But why?
As I was studying the muscles of the leg for drawing, it became clear that information technology is hard to become a grasp of all the muscles all at once.
I suggest studying anatomy for drawing in passes. If you lot are studying the anatomy of the legs for the beginning laissez passer, know that the adductor group is there and is important. In one case you are familiar with the rest of the muscles in this guide, the grouping can be revisited.
I will leave you with this drawing that shows the gracilis muscle, a major adductor, together with semitendinosus (hamstring group covered in a higher place) and sartorius (covered above). As I mentioned above, there are more adductor muscles to study, and there are more muscles to written report at the knee-to-foot section as well.
Muscles of the leg – simplified anatomy review, Origin and Insertion
| Insertion | Origin | Insertion |
|---|---|---|
| Quads (front of leg): | ||
| Rectus femoris | Anterior junior iliac spine, and groove superior to the acetabulum (right to a higher place the hip joint) | At the common quadriceps tendon enclosing the kneecap (patella). |
| Vastus lateralis | Greater trochanter area, at the front end (anterior) surface. | same as rectus femoris |
| Vastus medialis | Starting at the meridian of the femur and down along the medial section of the femur. | same as rectus femoris |
| Sartorius: | At the inductive superior iliac spine. | Insertion is at the top of the medial (inner) surface of the tibia bone. |
| Hamstrings (back of leg): | ||
| Biceps femoris | ischium -the curved bone forming the base of each half of the pelvis | femoris is on the lateral (outer) side of the head (tiptop) of the fibula. |
| Semi-tendinosus | Same as biceps femoris | Medial surface of the superior shaft of the tibia (inner surface of upper portion of tibia) |
| Semi-membranosus | aforementioned as biceps femoris | medial condyle of the tibia |
| Calves – gastrocnemius | Medial and lateral heads ascend from posterior surfaces of femoral condyles. (so back sections of the bottom tip of the femur bone!) | Back of heel of the foot via Achilles tendon |
| Glutes: | ||
| Gluteus maximus | Sacrum and coccyx, gluteal surface of ilium | Iliotibial tract, gluteal tuberosity of femur |
| Gluteus medius | Posterior department of the ilium (Gluteal surface of ilium ) | lateral surface of the greater trochanter (femur) |
| Tensor fasciae latae | Aterior superior iliac spine | Iliotibial tract – (IT BAND) that fastened to the lateral condyle of the tibia. |
| Adductors (grouped): | In that location are multiple muscles a the adductor group, they mostly originate from the pelvis | and inert at various points at the femur. |
Kneecap overview
Drawing the knee is a large topic and, so I created a divide tutorial going over cartoon the knee in detail. However, let'south touch on on the nuts of what is happening at the knee joint for drawing the leg.
At the human knee joint, condyles of the femur os and the tibia come together. A condyle is a rounded protuberance at the terminate of some bones, serving articulation with another bone. The condyles on both of these basic are massive and oft some of the bone of the condyle can be seen on the surface.
The patella (human knee cap), connects the tendons that unify the quad muscles – all of them wrap into information technology, then the patellar tendon moves down and connects at the to top of the tibia.
The identify where the tendon connects is a pointy bony flake, which sometimes tin can make information technology seem like there are two kneecaps, 1 on top of the other. Well, the i on the height is the human knee cap, the stuff underneath is its tendon that attached on top of the tibia – the patellar tendon.
At this signal we discussed at length the bones and muscles of the leg. Allow's now review the functions of the muscles, and then motion to drawing the legs stride-by-step.
four. How to Depict Legs – Muscle Function
Muscles of the leg – simplified beefcake review, Function
| Muscle | Function |
|---|---|
| Quads: | |
| Rectus femoris | Extension of the leg at the knee joint |
| Vastus lateralis | Extension of the leg at the knee articulation |
| Vastus medialis | Extension of the leg at the knee articulation |
| Sartorius: | Flexion, abduction, rotation of the thigh at hip, flexion and rotation of lower leg at human knee |

| Gluteus maximus | Extension and rotation of thigh at the hip articulation |
| Gluteus medius | Abduction and extension of thigh at hip joint |
| Tensor fasciae latae | flexion, rotation and abduction of thigh at hip joint |
| Adductors (grouped): | adduct thigh, flex thigh and rotate thigh. |
5. How to Draw Legs – step-by-pace examples
Cartoon legs – Example 1:
Let'southward take this cartoon of the legs step-by-step together:
When I draw-in these first marks on the canvas, I am measuring proportions, relative position (of one leg to the other), and angles at which the legs appear to the viewer. I endeavor to do this all at once in this beginning step.
Ofttimes information technology is a lot to think almost, especially when cartoon something complex like the legs, so take your time with this get-go step. Measuring things out, go back if you lot take to.
Feeling confident with the pose, I start to block in shapes.
At this fourth dimension I focus on orienting the main muscle groups, the quads prove up the most in this cartoon, so I focus on placing them. Recall the anatomy of the leg as you lot are drawing – this is where our anatomy overview (run across to a higher place) actually starts to become useful.
I know that at the front, three muscles of the quads are visible, vastus medialis on the within, vastus lateralis on the outside, and rectus femoris in between the two.
I know that the abdomen of the femoris muscle sits college on the leg. Information technology is much easier to spot all of this on the model when y'all know what you should run into when you draw.
Using this knowledge I place the muscle groups accordingly, non but based on the information I see in the model, just based on my framing of this information given the beefcake background I now have.
Subsequently placing the quads, I also added placement for the sartorius musculus, that divides the quads from adductors on the front of the leg.
The sartorius is most visible and easy to identify as a diagonal line running from the knee to the to of the hip.
I decided to draw over what I built so far with cleaner lines in this pace.
With structure and placement out of the mode, I tin can begin to shade the muscles of the leg to give our drawing of the legs some volume.
Shading is some other topic, but you encounter me adding some more here, I also (as you lot saw in the previous step) added a neutral colour to the unabridged epitome so that I could place white highlights.
Here I separated the drawing of the legs from the background by placing in a half-tone with a value closer to the shadow areas.
Although the drawing is not finished, I added some highlights to encounter where I am with book. I at present have the darkest darks and the lightest lights on my canvas and will piece of work inside these parameters to cease the drawing.
Finally, I added rendering particular and tried to define separate muscle groups by defining the volume of each.
Knowing the shape of the muscles volition ascertain how you approach rendering them, the placement of shadows and lights. While good reference can provide this information, combining it with your knowledge of muscle anatomy should produce fifty-fifty ameliorate results.
Hither is video procedure of the legs drawing higher up:
Drawing legs – Instance two:
Same every bit in the first case, I commencement with simple skeletal draft that defines the pose, angles and proportional relationships. I am thinking about the position of the anxiety, and identifying landmarks.
Happy with the placement and angles in the original sketch, I move the drawing along with some rough outlines of the shapes I am trying to develop.
Try to imagine the lines on paper before you draw them.
Having the foundation of the drawing finished, I added detail with a flake more confidence. You can already come across the adductors on the inside of the legs, besides every bit the sartorius musculus and some indication of the quad group.
Hither I drew in all of the muscles of the upper leg. Can yous identify the quad muscles? Vastus lateralis, rectus femoris and vastus medialis? Tin yous see the hamstrings or the tensor? If you can't identify these yet, don't worry, review the muscle section and come back to this sketch.
In this pace, I added some shadows to try to dissever the form from the sheet.
Here I added the mid-tones to the drawing, equally well as the darker darks.
And finally some highlights to place the forms of this sketch of the legs.
Drawing legs – Case three
Let's look at one more example:
I start this drawing like I did the other two, with a very basic skeletal outline of the angles and proportions. You should exist asking yourself things like – where is the knee on this leg in relation to the knee of the other? What are the angles of the anxiety in relation to one some other? – Always describe in context to other landmarks already on the page.
Once the basic angles and proportions look fine to me, I create a sketch shape outline noting major landmarks.
In this footstep, I added a stronger outline to ameliorate read the shape. I also separated the quads from hamstrings in the leg closest to the states.
Here I added a flake of shading and some drop shadows to situate the legs. If you are curious near lite and shading, bank check out my tutorial on exactly that at this link.
This concludes my step-past-step guide to cartoon legs. For me, leg anatomy has been more difficult to study than the other parts of the body, I hope I made it a bit easier for you lot with this guide!
Recollect that drawing legs is like drawing anything else – combine knowledge of the subject with drawing skills for best results. We spent a lot of time going over how to draw the legs, it is now time for you to put what you learned to practice!
