English [Auto] So the abdominal muscles. This is not really a long or complicated lecture and it's going to be pretty easy to put them on and you could see we have those cereus muscles that are going to the side and those turn into the leaks and from the back you can see a little you can see the obliques right here and then there's this space in the back. So that's important to remember and we also see our big deltoid muscle the cape that's coming over back itself is not going to be that difficult back is pretty much already done. But the abdominal muscles as I said these top two abdominals depending on who's drawing them sometimes you'll see this entire piece drawn as one and I just want you to look at the shape what will go in depth with the shape when I start to draw them with the drawing portion of the lecture. But notice that there are eight and these are long and they're attached from top to bottom and they are going all the way down into the groin area which makes kind of a V shape male or female abdominals or abdominals and along the side they are going to stop. They're going to stop at the hip. So that's going to be your landmark for your hips so that is also another reason why you see people drawing the hip as a disc or just some underwear or something to that effect. Because once that stops then we get into the gluteus muscles which would go ahead and do that when I start talking about the legs actually and not the back. We'll talk about it a little bit. Because unless you're drawing full on nude people chances are you just need to know the shape of the gluteus maximus and gluteus medius. So what I just want to show you is that these are divided up into sections and there's a slight pattern everybody's pattern to their abs. Most of us don't have abs when we have them. We just can't see them. And those of us that day you can see them there are all kinds of different patterns but they do follow a basic shape that you could see right here. And so we're going to go ahead and draw some apps and I just am going to explain them to you and explain what happens when they get larger. And explain what you will see in contrast to a woman when you're drawing a female form when you're drawing that. So you can see from the side they are kind of their ribs. They are ribbed on the side and you know everybody wants to get those ripped abs. And so let's go ahead and continue the lecture and the drawing portion of it. And so here we are drawing. So when I'm drawing abs that pesky red again when I'm drawing the abs. Well go ahead and make my quick little mannikin Whoops that's not nice. So we got the chest in here. OK. I'm a little bit too nutty. Anyway I tend to do this. This is the overall shape that I'm looking for. So I kind of start up here. It's slightly a little skinnier and it fans out. If you look at it you can also do this for the ABs this is what I basically want you to remember. The ABs are starting up this way and as they go down we get one that's straight and we have another one that's straight belly button right here. More or less. And there's white space in between here. I mean go back in and fill in the abs. Sometimes as I said before sometimes you'll see this entire top piece is just one see that entire piece is one where we're looking at it from the side we're going to see one two three and then we'll see it down here. They're attached. And you can see this first one is kind of going down. This one is this way right here and this arm flattens out and they are attached like this. So if I'm drawn a character and I'm drawing him the character bent forward and I got the chest right here. So what I'm looking at with the ABS is I'm just picking out this shape right here. I know that it is going insists in succession the top for the top portion of it is having it covered up and then I'll have like my cereus muscles coming in here. And I'm just going to use just draw a line representation. But as a cereus muscles come down that's when you get that. And that's all this is a bit more of a stylized version of it. But here right here is where you get your probably should move this up a little bit. But anyway that's where you're it's going to turn into. So we've got the cereus muscles and they're essentially doing this the cereus muscles are doing this. You don't have to keep trying each individual little portion of it. These are your love handles right here. The obliques the love handles and we know that we stop the love handles wherever the hip is going to be and you can see they're attached and sometimes you will also obviously see someone that just draws the love handles and draws them up in front how they're attached like this is not as big of a deal when you're drawing surface anatomy but as long as you know so basically when you see someone draw the love handles and you'll see them draw something like this and that's this area in here. And from the back we're going to have that little bit of space right there. That's basically what you're seeing from the side. So you see these characters drawn from the side chust shoulders to the arm right here. When you see people draw that portion right here they're drawn the love handles. That's going to be the back. We've got the serratus muscles going. The ABs are right about here. I think I'm drawn to everything a little bit too fast. I apologize when we slow down a little bit. So when you're seeing the the abdominals you're on and these are actually all on there on a skinnier person. These are not going to be as defined as you think unless they do a lot of abdominal exercises. But for the most part you're just going to see them. This wall is a series of lines here drawn the serratus that's cool. But just know that sometimes you'll see a diagram and it won't be is defined as this it'll just be all one shape one shade and it starts to angled down as it gets closer to the bottom. So if you're looking at it this way sources draw a basic basic human shape right here. Here's the chest. Here's that line for the abdominals. So your cereus is actually just doing this and then the ABs will be in the middle. So this top one is kind of up at an angle and then they angle their way down. So so I readjusts that when it comes to the belly button but that's where it's located at. So you can make your own adjustments and when you're looking at your photo reference. And again this is going to come out just slightly because these are actually the Open Leaks but I just want to want you to see that muscle is doing that. We're going to cut up the muscle obviously a lot more. Once we start putting it on to the figure and I want you to also notice all of the white space that's in between there and that's what gives you a lot of the definition. So there is a considerable amount of white space in between. So we'll want to keep that in mind we're putting on the abdominals. So let's go ahead and put the abdominals on.
