this guy here
you're gonna see this tendon comes and attaches.
under-ish the big
underish the big toe.
right
Come on.
Slight foot fetish going on here. There we go. Okay.
So you see that little yellow piece?
Coming in right there, right? So that
attaches to the big toe portion,
right? So when it lifts it lifts through that portion of the foot.
These guys running underneath here, right? Those are
the actual tenderness portions
of the gastroc. So the gastroc actually
comes down to the four little toes, right?
So when we look at the lower leg,
there's going to be a separation and function between the
Soleus the two divisions
of the gas Rock and on the front of the leg. There's going
to be a separation between the anterior tibialis
and the anterior flexors
that pull up the small toes or
these small carpal bones of the
foot.
All right, so let me move now.
to our posterior side here
lateral head of the gastroc here
Right. This will actually go better when we have the our
life model here, but she can or
but the muscle
this this lateral one is going to come down.
And it's actually going to be the two tendons that
run to the outer toes and the medial ones going
to come and it's going to be the ones that are to the second and
third toe.
From mid right? So you're ring and middle
toe if you will right our soleus muscle underneath
here.
right
It doesn't run under the foot. It just pulls
for the most part. But because it
doesn't do the other four it moves the whole foot, but
which is mainly going to be driven through the big toe. So
when we're looking at
The lower leg we're gonna have well, we could emphasize pressing
more at the big toe. We could emphasize pressing more
at the medial too little Toes or the lateral
to Middle toes and we'll talk about how that actually
plays out. When we do the whole toes in and Toes out thing and
why there's actually some truth to that but it's not it's
not this that matters. It's actually how
that footplate is pushing into the foot that is
making the difference on what is being loaded.
All right, so my my knee flexors here.
Okay.
Got both divisions of the gas Rock they cross.
the knee
and they wrap around.
Right. So they've essentially function like reaching
around here and grabbing and pulling
this this way, right? So
they are very strong knee flexors
in this position because they basically they
get to use the thickness of this these knobs in
the back of the femur as levers to do that.
and the knee extended position
so I can get it to rotate around here my hamstring tendons
f****** suck as knee
flexors, right? They're pretty much pulling the joint
just together, right? So when
we're looking at knee flexion knee flexion is going to be done primarily
by the gas Rock in the most lengthened
position and then once it gets up here, that's when
the things that attach down here are going to then gain
leverage and be the stronger flexors in
the top portion of the range, right? So knee extension
is going to be a harm or knee flexion is going
to be Harmony of gastrocs doing this
part of the motion and then the hamstrings in varying
degrees of participation taking over
the rest of the motion this same thing
plays out in the elbow.
We talked about it a little bit with.
This guy having a significantly different Vector,
right? And he kind of gets to he doesn't have a bony
thing that he comes over but he comes over all of these other forearm
muscles and so he kind of uses them as the lever
down here. Right? So his fulcrum right
is based off of flapping over all your
other tissue because it's the most superficial of those
elbow flexors. So it gets to leverage, you know, your pronator
your supinator all of your flexor extension
muscles that sit in here right to be able to help in
that fully lengthened position, but then once it gets up here, then
it's these other elbow flexors to varying degrees,
right so and we'd think that like, okay.
The biceps would be great in this middle position as we come
here. The brachialis would actually be a little bit more helpful in that
short position. Okay, so we'll see that
kind of plays out.
With our hamstrings as well.
So I'm going to rotate this here. So you guys can see
all these.
Little attachment points. So you notice
Right, the gas drop comes in behind the knee.
And the hamstrings have to go.
Around the joint right? Because otherwise everything that
like if these guys came here, they would have to go through the calf. But
in reality it's the calf comes in between
and separates the hamstrings and that's why the
back of the leg you look at it. It looks like this at
the bottom right with a little thing coming up the middle,
right? You see like this little, you know, you'll see this little
triangle coming up and then you'll see like this this little open
slice in the bottom, right? Okay.
So then as we move up.
All of our hamstrings attach to the
posterior side of this pelvis, but they attach
if we look at it laterally.
There's not that much of a difference but slightly
so you can see here that one of those is
most more post here one of those more anterior
and one of some kind of middle. So the ones that are
the furthest this way on the hip will be
slightly stronger leverage in
terms of hip extension and the ones closer
will be not as good but it's not that
big of a difference.
But except that you also have to count for they are layered
over top of things. Right? And so that does kind
of change their pull a little bit but
without sending here and trying to
tell you guys how all of this stuff layered up
is we can actually just look at the knee.
And see that this is actually going to be the largest influence. So
you see those two tendons there.
So we have the medialis.
attaches very close to the Joint
And then we have the tendinosis.
Which attaches very?
You know, let me just can't get rid of
my calves in this view. But you see that you see it the tendon coming
way down here.
Right again.
Not to brag but I think my drawings are better. So it'll
make more sense. We going her right? So that means is
the knee bends.
One of these guys is pulling from here.
And one of them is pulling from here.
so
sir, Wade
work with me buddy work with me. There we go.
so sir, Wade
tendinosis
member gnosis
so see the difference see how
much further this one is.
From the axis. So this one is going to
be have better leverage for knee flexion than this
one is right. So if these guys were
trying to manage
knee flexion
But not as but not as much hip.
My brain would say well I'm gonna put
more into this one than this one because for the
same amount of tension in the muscle, which is going to
be very close to the same force of the hip I get a lot
more knee flexion if I contract the tendonosis then I
do the member gnosis.
So this one is slightly more knee flexion biased. This
one is slightly more hip flexion
or hip extension bias. Okay blue is
tendinosis.
Yep.
Tendinosis goes further down. Okay. Yep.
so
Okay, so then on this side.
Okay with what's this muscle? What's the
lateral hamstring called?
Biceps femoris, right and it has two bellies
one.
that attaches here this looks like what muscle
in the
arm
Brachialis, and so then this one goes
all the way to the hip. So on the lateral side if I wanted
to buy his knee flexion. It's much easier here. It's like well just use the
one that doesn't even cross, right? So this is the most knee
flexion biased of the hamstrings obviously because
it doesn't have any influence of the hip right but this
one is going to be very hip extension
biased and comparison to this.
So on each side of the leg. We have one hamstring
that is a little bit more favorable to knee flexion one. That's
a little bit more favorable to knee extension. So based
on the relationship if I'm doing a squad
or pull or whatever whether I need a little bit more hip
extension or a little bit more knee extension going on.
My body can actually use those hamstrings to
varying degrees right once we get to the point
where we need as much as possible. That's where
then in order to use. The more of the things that the
knee the Quant would have to be actually resisting the
knee flexion component, right? And that's where
we're going to start to see things in like, all right, people doing powerlifting are
actually getting to that threshold. But even your regular
people if they're training close to failure might be
getting to that position where you will see their technique shift
because they now need the other
hamstrings that maybe weren't as good a hip extensors
to start participating because the rest of
the hip extensors are fatigued and so when you see
that you could be like, hey stop cheating you're doing
like s***** technique or whatever but really you could
just be like, well, they technically have the ability to move this load. They
just don't have the ability to move it and the technique that they could when
they were fresh or when the weight was lighter, right and so
from a training perspective.
You could say hey if I know that that is the case. I
can choose positions for this person and techniques for this
person that allow them to go to fatigue without having to
change their technique or if there are powerlifter. I can
adjust their technique that allows them to maximum capitalize on
their structure and those muscles right because basically,
you know, based off of somebody's levers.
This isn't a powerlifting course, but they might be better doing a
combination motion that's more squatting or they might
be better doing a press and pull motion or if they're really
fortunate. There might be just one of those people where they just do
like a partial RDL because they have like tiny femurs
and like monkey arms, right? And those
are the people that powerlifters hate right Miller.
Because they're not power lifters. They're deadlifters.
800 pound deadlift 200 pound bench
right like
yeah.
But because because you just total all those things together,
you can just be a deadlifter and you can win a
powerlifting meet.
