THE ALIGNMENT MAP

The Hundred begins our assessment by establishing the relationship between your center and your limbs.

As your legs straighten and travel farther away from your body, their leverage increases.

The question isn't: how low can you get your legs?

It's: how low can your legs travel before your pelvis or low back changes position?

Can your ribs and pelvis remain organized while the legs create progressively more demand? Can your arms pump vigorously without your shoulders and rib cage bouncing along with them? Can you continue to breathe while maintaining that organization?

Notice:

• Can you maintain your trunk organization as your legs reach away?

• How low can your legs travel before your pelvis or low back changes?

• Can your arms pump without disturbing your trunk?

• Can you breathe fully while maintaining the position?

• Does your alignment deteriorate as you fatigue?

YOUR ALIGNMENT MAP TAKE AWAY

Lower isn’t better.

Your Hundred reveals: how well can your center support increasingly long levers?

WHY THIS MATTERS FOR RUNNERS

Running connection: Trunk stability while the legs move

Running repeatedly asks your legs to move underneath you while your trunk manages the forces traveling through your body.

The Hundred lets you explore how well you can maintain the relationship between your rib cage and pelvis while your legs move farther away from your center. As the legs lower, their leverage increases — and your trunk has to respond without simply changing position to accommodate them.

For a runner, this is an opportunity to notice whether you can create movement from the hips while maintaining an organized trunk.

THINK ABOUT IT

Can your legs create force and movement without taking your trunk along for the ride?

The Roll Up begins before you ever leave the mat.

Start lying flat with your legs long and your arms reaching toward the ceiling. Slowly reach your arms back toward the mat behind you.

Before going any farther, notice what happens to your upper body.

Checkpoint 1 — Arms overhead

Can you reach your arms behind you while keeping your upper back and rib cage connected to the mat?

As the arms travel overhead, notice whether your ribs begin to protrude or lift away from the mat. If they do, you've found useful information: your arms have traveled beyond the range in which you can currently maintain the organization of your trunk.

Bring the arms forward slightly until you can reconnect the ribs and upper back.

That's your range today.

You're not trying to force your hands to the floor. You're looking for the relationship between shoulder mobility and rib-cage organization.

Ask yourself:

• How far can my arms travel overhead before my ribs begin to lift?

• Can my upper back remain broad and connected to the mat?

• Does one shoulder feel different from the other?

• Can I breathe normally while maintaining this position?

• If I decrease my range slightly, can I find a more organized position?

Checkpoint 2 — The Roll Up

From there, begin your Roll Up.

Can you bring your arms forward and initiate the movement through your trunk rather than throwing your arms for momentum?

Notice how your spine leaves the mat.

Can you progressively peel the head, shoulders, ribs, and spine away from the mat, or is there a point where your body wants to move as one rigid piece?

Ask yourself:

• Can I roll up without using momentum?

• Can my legs remain long and grounded?

• Where is my “sticky spot”?

• Do my ribs suddenly thrust forward as I move through a difficult point?

• Can I maintain the shape of my trunk as I reach forward?

Checkpoint 3 — The return

Now reverse it.

The way you return to the mat may tell you even more than the way you came up.

Can you control your pelvis and sequentially return your spine to the mat, or do you reach a point where gravity takes over?

Once your upper back and head return, reach the arms overhead again.

Can you finish in the same organized position you started in?

What you're assessing

Shoulder + upper-back mobility

Can your arms travel overhead without requiring your rib cage to lift and your trunk position to change?

Spinal articulation

Can your spine progressively lift one bone at a time rather than moving as one rigid unit?

Center

Can you organize your ribs and pelvis while your arms and spine move?

Dissociation

Can movement occur at the shoulders without automatically creating movement through the rib cage and spine?

Control

Can you move against gravity using your strength, not momentum, on the way up — and control gravity on the way back down?

YOUR ALIGNMENT MAP TAKE AWAY

Touching your toes isn’t the goal.

The assessment is noticing where your shoulder range ends and your rib cage begins compensating for it. Then, as you Roll Up, you're asking the same question in a different way: where can your body move while maintaining its organization — and where does that organization begin to change?

Your Roll Up reveals: how well can you coordinate shoulder mobility, rib-cage organization, and spinal articulation as you move against gravity?

WHY THIS MATTERS FOR RUNNERS

Running connection: Rib-cage organization, shoulder mobility + spinal movement

Your arms don't run independently of the rest of you. Your arm swing, rib cage, spine, and pelvis are all part of the same moving system.

The Roll Up gives you an opportunity to assess whether your shoulders can move overhead without requiring your ribs to protrude, and whether your spine can articulate while your pelvis and legs remain organized.

Why does that matter for running? Your upper body needs enough freedom to move without creating unnecessary movement elsewhere. If moving your shoulders consistently requires you to change the position of your rib cage and spine, that relationship may also influence how you organize yourself when you're upright and moving.

The Roll Up also asks you to control your spine against gravity rather than simply holding your torso rigid.

THINK ABOUT IT

Can your upper body move freely without disrupting the organization underneath it?

Single Leg Circles give you a very clear environment for observing the relationship between your leg and your pelvis.

One leg reaches toward the ceiling while the opposite leg remains long on the mat.

Now circle the lifted leg.

The question isn't simply how large you can make the circle.

How large can you make your circle before your pelvis has to help you?

Notice whether the femur can move freely inside the hip socket or whether the pelvis is being pulled along with it.

A smaller, controlled circle may tell you more about your usable hip mobility than an enormous circle created by moving the entire pelvis.

That doesn't mean pelvic movement is inherently wrong. As the Classical exercise progresses, larger circles may incorporate controlled, intentional movement.

The important distinction is:

Can you tell the difference between movement you're choosing and movement you can't control?

Notice

• Can your opposite leg remain long and organized on the mat?

• Can you maintain the organization of your pelvis?

• How large can your circle become before your pelvis begins to join?

• Can you maintain the organization of the leg throughout the circle?

• Is one direction easier than the other?

• Is one hip noticeably different from the other?

• Can you make the circle smaller and more precise?

YOUR ALIGNMENT MAP TAKE AWAY

Bigger circles doesn’t necessarily mean better hip mobility.

Your range ends where your control ends.

Your Single Leg Circles reveal: can your leg move freely inside your hip while your pelvis remains organized?

WHY THIS MATTERS FOR RUNNERS

Running connection: Hip mobility independent of the pelvis

This is one of the most directly relevant Alignment Map exercises for runners.

Every stride requires one femur to move in the hip socket while your pelvis and trunk manage the rest of your body.

Single Leg Circles let you see how much movement you can create at the hip before your pelvis has to join the movement. If you make the circle enormous but your pelvis rolls with your leg, you haven't necessarily demonstrated more usable hip mobility — you've changed where the movement is coming from.

For runners, we're interested in developing enough freedom at the hip that the leg can move without asking the pelvis and low back to manufacture all of the additional range.

THINK ABOUT IT

Are your glutes and abdominals working together to keep your pelvis organized as your leg moves?

Rolling Like a Ball gives you a unique opportunity to use the mat itself as feedback.

Start by sitting directly in the center of your mat. Draw your knees toward your chest, hold your ankles, and balance behind your sit bones. Create a compact, rounded shape through your spine.

Then roll backward along the length of your spine and return to your starting balance.

The goal isn't simply to get down and get back up.

Pay attention to where you land.

Checkpoint 1 — Can you create the ball?

Before you roll, notice your starting position.

Can you bring your knees comfortably toward your chest? Can you hold your ankles while maintaining your balance? Can you create an even curve through your spine rather than collapsing into one particular area? Can you balance without putting your feet down?

Your ability to create the starting shape matters. The more evenly you can distribute the curve through your spine, the more smoothly you have the potential to roll along it.

Checkpoint 2 — Follow your spine

As you roll backward, notice the pathway your body takes across the mat.

Ideally, you're trying to roll along the center line of your spine rather than falling heavily into one particular area or consistently drifting toward one side.

Think of your spine like the curved surface of a wheel. You're trying to create a smooth enough curve that your body can roll backward and forward without getting stuck, flattening out, or changing direction.

Notice:

• Does one part of your back hit the mat more heavily?

• Is there a section you seem to skip over?

• Do you consistently roll toward your right or left side?

• Does the shape of your body change as you roll?

• Do you need to kick your legs to generate enough momentum to return?

You're not trying to “fix” anything yet.

You're collecting information.

Checkpoint 3 — Where did you land?

Before your first repetition, notice exactly where you're sitting in relation to the front and center of your mat.

Roll back and return.

Are you still there?

Repeat the exercise several times.

If you began facing straight toward the front of your mat but gradually find yourself turned, shifted, or traveling toward one edge, take note.

Your mat has essentially become a set of grid lines underneath you.

Consistently drifting toward one side can reveal a right-to-left asymmetry in how you're organizing and moving through your spine. One side may be interacting with the mat differently from the other.

The goal isn't to diagnose why from this exercise alone. The goal is simply to recognize:

My body isn't traveling symmetrically right now.

That's valuable information to take into the rest of your practice.

Checkpoint 4 — How does your spine feel afterward?

Rolling Like a Ball also gives the spine a very different experience from the compression and loading it encounters throughout everyday life.

You're repeatedly moving a rounded spine across the mat, creating a gentle massage-like effect along the back.

Rather than thinking of “decompression” as something you achieve once and permanently keep, notice how your spine feels after several controlled repetitions.

Do you feel more spacious? More mobile? More aware of the individual sections of your back? Does sitting upright afterward feel different?

That sensory information matters, too.

Notice

• Can you comfortably create a compact, rounded shape?

• Can you balance without putting your feet down?

• Can you roll smoothly along the length of your spine?

• Does one area of your back make noticeably heavier contact with the mat?

• Do you consistently drift toward one side?

• After 3–5 repetitions, are you still facing straight forward?

• Can you return to balance without kicking your legs or changing your shape?

• Does your spine feel different after you finish?

YOUR ALIGNMENT MAP TAKE AWAY

Can you use your center to create—and control—your momentum?

Rolling Like a Ball asks your deep abdominals to maintain a compact, rounded shape as your entire body moves through space, building core strength while gently massaging the spine and challenging your balance and coordination. The goal is to control your momentum, maintain your shape, and return to balance without kicking your legs or putting your feet down. Your pathway across the mat can also reveal right-to-left asymmetries, but the bigger question is: Can your center organize and control your body as it moves through space?

WHY THIS MATTERS FOR RUNNERS

Running asks your body to maintain control and coordination while continuously moving through space.

Rolling Like a Ball challenges your deep abdominal strength while teaching you to control momentum, maintain the shape of your spine, and return to balance without relying on your legs to get you there.

The rolling action also gives your spine a gentle massage and encourages movement through the full curve of your back — a useful counterpoint to the repetitive loading your body experiences while running.

For a runner, the goal is to develop a center that can organize your body while it's in motion, rather than only when you're holding a static position.

Your pathway across the mat gives you additional information, too. If you consistently drift toward one side, you may be noticing a right-to-left difference worth paying attention to.

Ultimately, Rolling Like a Ball asks: Can your core control your momentum, coordinate your whole body, and bring you back to balance?

THINK ABOUT IT

Are your glutes and abdominals working together to keep your pelvis organized as your leg moves?

The Abdominal Series gives you five consecutive movement problems.

Instead of thinking of these as five exercises you need to “get through,” notice what changes as the demands become progressively more complex.

Single Leg Stretch

One hip folds while the other leg reaches away. Can your pelvis remain organized while your legs perform two different jobs? Can you switch sides without rocking or shifting through your trunk?

Double Leg Stretch

Now all four limbs travel away from your center. Can your arms and legs reach away while maintaining the relationship between your ribs and pelvis? How far can your limbs travel before your trunk needs to change?

Single Straight Leg Stretch

Now straighten the knees. The exercise adds another mobility demand through the backs of your legs. Can one hip flex while the opposite leg reaches away? Does one side feel different from the other? Can you maintain your center while your legs become longer levers?

Double Straight Leg Lower/Lift

Both legs become one long lever. This gives you one of the clearest opportunities in the assessment to ask: Where does my controllable range end? Lower isn't better. How far can your legs travel before your pelvis or low back needs to change position?

Criss Cross

Finally, add rotation. Can your trunk rotate while your pelvis remains organized and your legs continue performing opposing actions? Can you coordinate the movement without simply pulling your elbow toward your knee? What happens as the complexity increases?

YOUR ALIGNMENT MAP TAKE AWAY

Complexity reveals organization.

Your Abdominal Series reveals: can your center remain organized while your limbs become progressively more independent, longer, and more complex?

WHY THIS MATTERS FOR RUNNERS

Running connection: Reciprocal movement around an organized trunk

This may be the most obviously “runner” section of the assessment.

Running is reciprocal. One hip flexes while the other extends. One arm travels forward while the other travels back. Your trunk manages those opposing forces continuously from stride to stride.

The Abdominal Series progressively asks your body to solve similar organizational problems.

For runners, the value isn't that these exercises “look like running.” They don't. The value is that they teach your body to manage different movements simultaneously around an organized center.

THINK ABOUT IT

Can your right and left sides perform different jobs without losing the organization of your midline?

Spine Stretch Forward can look deceptively similar to a seated forward fold — but we're looking for something different.

The goal isn't to see how far you can reach toward your toes.

We're using the exercise to explore how much length and articulation you can create through your spine while maintaining the organization of your pelvis underneath you.

Sit tall with your legs straight and slightly wider than your hips. Reach your arms forward at shoulder height.

Before you move, notice where you're sitting.

Checkpoint 1 — Can you get vertical?

Before you assess how far you can move forward, assess your starting alignment.

Can you sit directly on top of your sit bones with your spine tall? Can your legs remain straight without forcing you to collapse backward? Can you stack your rib cage over your pelvis without gripping or excessively arching your back?

If sitting vertically with straight legs is already challenging, that's part of your assessment. Don't rush past it just to reach farther forward.

Checkpoint 2 — Keep your tailbone behind you

Now begin to reach forward.

Here's the important distinction:

Don't try to get farther by tipping your entire pelvis forward and folding from your hips.

As you begin to round your spine, imagine keeping your tailbone reaching behind your sit bones rather than sending your entire pelvis forward with you.

Your pelvis becomes the foundation. Your spine moves away from it. That creates opposition:

Tailbone reaches back.
Spine stretches forward.

This is very different from keeping your back flat, hinging forward at the hips, grabbing your feet, and pulling yourself deeper into a stretch.

Checkpoint 3 — Use your abdominals to create the shape

Remember all of the abdominal work you just did?

Use it here.

Spine Stretch Forward isn't a passive stretch where gravity pulls your torso toward your legs.

Use your abdominal strength to actively draw your trunk inward and create the rounded shape of your spine.

Think of your abdominals helping to lift your spine up and over an imaginary object rather than allowing your chest to simply fall toward the floor.

Your reach forward should come from the length you're creating through your spine — not from pulling yourself toward your feet.

Then ask:

How far can I articulate my spine forward while keeping my pelvis organized underneath me?

That is much more useful than: How close can I get my hands to my toes?

Checkpoint 4 — Where does your spine actually move?

Now pay attention to the shape.

Can you create an even curve from your head through your upper, middle, and lower spine? Or does one section move significantly more than another?

Maybe your upper back rounds easily, but your lower spine barely participates. Maybe you have plenty of hamstring mobility and can reach very far — but most of that distance comes from folding at your hips. Maybe you don't travel very far at all, but you're creating a beautiful, controlled curve through your spine.

Farther isn't necessarily better.

You're assessing where the movement is coming from.

Checkpoint 5 — Can you come back up?

Now reverse it.

Can you use your center to rebuild your vertical alignment? Rather than simply throwing your shoulders backward, progressively return your spine to upright until you're sitting tall over your sit bones again.

Then check your grid lines. Are your shoulders stacked over your ribs? Are your ribs stacked over your pelvis? Are you still centered between your right and left sit bones?

Can you return to the same alignment you started with?

Notice

• Can you sit upright on your sit bones with straight legs?

• Can you maintain your pelvis underneath you as you begin moving?

• Can you keep your tailbone reaching behind your sit bones rather than tipping your entire pelvis forward?

• Can you initiate the movement by rounding your spine rather than hinging at your hips?

• Can you use your abdominals to actively create and support the curve?

• Where does your spine move easily?

• Where does your spine feel less willing to articulate?

• Can you maintain length rather than collapsing toward your legs?

• Can you return to vertical with control?

YOUR ALIGNMENT MAP TAKE AWAY

Reaching your toes doesn't tell me how well your spine moves.

You can have extremely flexible hamstrings, hinge deeply at your hips, grab your feet — and demonstrate very little articulation through your spine. Spine Stretch Forward asks a different question: can you keep your pelvis organized underneath you while actively creating length and articulation through your spine?

The distance you travel matters much less than where that movement comes from.

WHY THIS MATTERS FOR RUNNERS

Running asks your spine, rib cage, pelvis, and hips to work together — but that doesn't mean they should always move together.

If your body has limited movement options in one area, it may find the movement it needs somewhere else.

Spine Stretch Forward helps you distinguish hip mobility from spinal mobility and gives you an opportunity to explore how independently you can move your spine while maintaining the organization of your pelvis.

For a runner, we're not trying to make your spine as flexible as possible. We're developing movement options.

Your hips can move when your hips need to move.
Your spine can move when your spine needs to move.
And your center can help organize the relationship between them.

THINK ABOUT IT

When your body moves, do you know where that movement is actually coming from?

Swan gives us the extension counterpoint to the flexion you've explored throughout much of the assessment.

As you lift your chest away from the mat, don't make the goal: how high can I go?

Instead, notice where the extension is coming from.

Can your upper and middle spine participate? Can you maintain length through the front of your body? Or does most of the shape concentrate in the area of your low back that already moves easily?

Can you come only as high as you can maintain length and organization — and then lower yourself with the same control?

Notice

• Where do you feel the extension?

• Can your upper and middle spine participate?

• Does the movement concentrate primarily in your low back?

• Can you maintain length through the front of your body?

• Can your shoulders remain organized rather than shrugging toward your ears?

• Can you lower with as much control as you lifted?

YOUR ALIGNMENT MAP TAKE AWAY

More extension isn't automatically better.

More isn’t always more. Your Swan reveals: is your extension distributed through your body — or concentrated in the places that already move easily?

WHY THIS MATTERS FOR RUNNERS

Running connection: Extension without dumping into the low back

Running requires extension — not only flexion.

As your leg travels behind you during stride, your body needs to manage extension through the hip while maintaining an organized relationship between the pelvis, rib cage, and spine.

Swan lets you investigate where your body finds extension. Can your upper and middle spine participate? Can you maintain length through the front of the hips? Or does most of your “backbend” come from one highly mobile area of your low back?

More extension isn't automatically better. For a runner, we're interested in whether extension can be distributed and controlled, rather than repeatedly borrowed from the easiest place to move.

THINK ABOUT IT

When you arch your back, where is the movement actually coming from?

Set yourself up on your side and establish your alignment before you begin moving.

Then let the top leg move.

Can your pelvis remain stacked while your leg swings forward? How far can the leg travel behind you before your low back begins to arch? Can you lift the leg without hiking your hip? Can you circle your leg without circling your entire pelvis?

Once again: the question isn't how far you can kick. It's how independently your leg can move while the rest of your body maintains its organization.

Notice

• Can you establish a stacked pelvis before you begin?

• Can your top leg swing without changing your waist or trunk?

• How far can the leg travel behind you before your back begins to arch?

• Can you lift the leg without hiking the hip?

• Can you circle the leg without circling the pelvis?

YOUR ALIGNMENT MAP TAKE AWAY

How far your foot travels doesn't matter if your hips can't stay stacked.

Your Side Kick Series reveals: can one hip stabilize while the other leg moves?

WHY THIS MATTERS FOR RUNNERS

Running connection: Pelvic stability while one leg moves

Running is essentially a repeated single-leg activity.

Again and again, one side of your body has to organize and support you while the opposite leg moves through space.

The Side Kick Series gives us a beautiful environment to observe that relationship without the additional demands of standing.

Can your pelvis remain stacked while your leg moves forward? Can your leg travel behind you without your low back arching to create the range? Can you lift the leg without hiking your hip? Can you circle your leg without circling your entire pelvis?

The question isn't how far you can kick. It's how independently you can move your leg while maintaining organization above it.

THINK ABOUT IT

Can one side of your body stabilize while the other side moves?

Swimming introduces a cross-body coordination problem.

Right arm + left leg. Left arm + right leg.

Begin slowly. Can you find the pattern? Can one shoulder and the opposite hip move without your entire trunk being pulled along with them?

Then gradually increase the tempo. What happens?

If the pattern looks organized slowly but begins to fall apart as you speed up, you've found your current coordination edge.

Speed doesn't create coordination. It reveals it.

Notice

• Can you easily find the opposite arm/opposite leg pattern?

• Does one diagonal feel easier than the other?

• Can your limbs move without excessive rocking through your trunk?

• Can you maintain your extension while the limbs move?

• Can you breathe while maintaining the pattern?

• What changes when you increase your speed?

YOUR ALIGNMENT MAP TAKE AWAY

Speed doesn't create coordination. It reveals it.

Your Swimming reveals: can your body coordinate opposing limbs across an organized trunk?

WHY THIS MATTERS FOR RUNNERS

Running connection: Cross-body coordination

Your gait is a cross-body pattern.

When one leg travels forward, the opposite arm travels with it. Forces have to be managed diagonally across the trunk as your body moves from one stride into the next.

Swimming gives you a simple way to explore that contralateral coordination: right arm + left leg, left arm + right leg.

Can you find the pattern slowly? Can you maintain it as you increase the tempo? Can your limbs move without your entire trunk rocking from side to side? And can you keep breathing while you do it?

Swimming isn't trying to imitate your running stride. It's asking your nervous system to solve a coordination problem that's highly relevant to gait: organizing opposite limbs around your center.

THINK ABOUT IT

How well do the opposite sides of your body communicate with each other?
