Talking about the leg lecture.
It's really important to think about the
legs.
In terms of cones.
So, when you have the figure like that.
The legs are always going on a diagonal.
Like this, and you have to think about.
If you break it down, into it's simple
shape.
You're thinking about it, like a cone.
Now, if this is the top of the pelvis,
like this,
the legs are always emerging from the
pelvis.
So, you ever see, those dolls where the
legs.
Kinda, connect right in here.
So, this is the front upper part of the
leg, and
this is the bottom part of the leg.
So, to simplify these,
just really think about it as two cones
moving diagonally down.
Connected by another square shape.
Which, would be the knee, the patella.
So, that, that is a super simple way of
breaking the leg down.
As you get more dynamic.
You, wanna, think about it, in a different
way.
You wanna, think about it as kinda, having
a rhythm and an energy to it.
So, you're using this principle, but your,
your leg is still pulling from the hips.
Like this.
But you're pulling down.
[SOUND] And down like that.
So, you're still thinking about it
sculpturally.
But, it's pulling down all the way like
that.
Okay.
So, knowing that the legs.
Come out and start from the top of the
pelvis.
We want to really, make sure to get that c
curve.
Like this, and another c curve and the
other c curve.
Like that.
Now the calf muscles, which are called the
gastrocnemius muscles,
are going to always be on a diagonal.
So this is, I'm looking at the figure and
this is the right leg.
The calf muscles, are going this way and
that way.
And this tibia here, which is the shin,
that comes down like that.
These bones
are going to be in front of those calf
muscles, like that.
The ankles are gonna, actually be counter
directionally of the calf muscles.
[SOUND] So, they're going to be this way
and that way.
And that is really the same rhythm that
will that the figure has been built on
for the entire.
Anatomy lesson.
The figures of these are always going to
be, those counter balance
positions of the legs, the arms, the
torso, the ribcage, everything.
So, just look for those.
Look for the, those, the calf muscles
lining up this way, and
the ankles lining up this way, et cetera
and so on.
[SOUND]
So.
[SOUND]
You could see here that.
The tensor facia lata is coming down, all
the way here.
Like this.
[SOUND]
And that.
A gluteus medius.
[SOUND] It's connecting in here and
pulling down.
[SOUND]
So, you really think, we'd wanna get, you
wanna get the basic rhythm of that.
[SOUND]
So,
it's the basic movement of that leg is C
curve to C curve.
C curve to C curve, like that.
And from the side,
side is gonna be C curve.
This direction to C
curve that direction.
So one two rolling like water.
And the ankle, coming down.
One move into the calf.
And really, what you wanna, do is.
You wanna, have one move here,
S curve into here and this going right to
the ground.
Grounding it
like that.
So it's.
[SOUND] It's one two ground.
[SOUND]
Like that.
[SOUND]
Okay.
[SOUND]
[MUSIC]
So
now we're gonna look at the back of the
leg, and
it's all of its beauty in all of its
glory.
We're gonna isolate also three muscles
that are really interesting and, and
can also be used as landmarks, depending
on the model.
Sometimes when there's a heavier model,
it's gonna be hard to see.
When there's a thinner model, it would be
really obvious.
But, at the same time, I would emphasize
not to really rely on anatomy.
In other, in other words, don't put
anatomy in there when it's not necessary.
Sometimes that can take away and
tar, start to kinda like isolate the
entirety of the figure.
When you start isolating all these
different muscles,
you kinda lose the overall essence and
spirit of the pose.
So, I would advise to use anatomy
sparingly and
intelligently to help elevate the
aesthetics of a drawing, not as a crutch.
Just because well, I know that the
iliotibial band is there, so
I'm gonna put it right in there, and I'm
gonna you know, outline it.
That's gonna really just kinda bring all
the attention to the illiotibial band,
or all the attention to the bicep femurs,
or all the attention to the gastrocnemius
muscles.
When in reality, you wanna know it's
there, but
be very subtle about showing that.
So let's go over, the back of the leg.
So here you really first just want the
general direction of the leg, obviously.
So, and you want once again, you've got
beautiful curve, this beautiful curve.
You've got the pelvis broken down into a
box like this.
And you've got this beautiful curve there
and
beautiful curve with the leg like that.
Okay so, that is the energy and the spirit
of that and that's great.
So, now let's look at it a little further.
You have the sacrum here, what we talked
about before.
And you could even feel around that.
You have these two big muscles here coming
down,
and that is the, the gluteus maximus.
And these legs, And just think about them
right now as cylinders.
Beautiful cylinders, but cylinders.
And these legs are going this direction
and this direction like that.
So, the gluteus
tucks under here all the way here like
that.
This comes around like that.
Really feel it kinda wrapping,
wrapping this direction with the other
leg.
Once again, you wanna just feel that form
like that.
And this gluteus wraps around as well,
like that.
Okay, so you've got these gluteus muscles
that are wrapping around the figure like
that.
And then you've got her hamstrings, and
her hamstrings are wrapping down and
attaching here.
See that?
You could see on the other side.
And those are attaching there.
Those hamstrings are doing that.
And then you have the gastrocnemius, which
you could see very pronounced on her.
Where, those are the calf muscles,
otherwise known as the calf muscles, and
there's two of them.
One is fitting in here.
Like that.
That's kinda tucking in under there like
that.
You can see it gets darker under here like
that.
Like that.
So same here, the hamstrings are pulling
down like that, and wrapping.
See that line there on her?
It's wrapping down.
That's that hamstring.
And it fits right underneath here.
Like that.
Now that calf, as you can see,
splits into two, the two heads of the,
of the gastrocnemius and
runs underneath this hamstring.
Now all these muscles help flex the knee
joint.
And all these different muscles have
kinda, different angularities to them.
And the Achilles tendon goes down like
that.
It goes down to the Achilles Tendon.
Yeah.
One side of the ankle is here,
the other one is lower there.
Just like one side of the gastrocnemius is
there, other one is lower.
And when you add everything else,.
You're getting that.
Achilles Tendon.
Like that.
Okay, so that is the back of the legs.
You can use anatomy to guide you,
but don't let it control you.
It's good to have a working understanding
of it.
Not to know every little tiny detail and
muscle and tendon, but
to have a basic understanding of it.
