The movement assessment: reading a student's body before you correct it

A movement assessment is the skill of LOOKING at a student's body through the lens of function and position: what is this joint doing, which muscle is working, which part is off axis — and not reciting a list of muscle and bone names.

• Demolishing the first fear: you do NOT have to remember hundreds of muscles. The standard yoga anatomy texts say clearly — what is needed is to UNDERSTAND the function of a few KEY structures in their context, in order to optimise a pose, break through a restriction and avoid injury.
• This is a NEW LANGUAGE, and it becomes familiar as you learn it — not as frightening as it looks.
• The professional purpose: understanding how joint, muscle and connective tissue work together, so that you teach SAFELY and INTELLIGENTLY; knowing 'what the practice is demanding' and 'which action gives the best result'. This knowledge is invisible to the student but gives you CONFIDENCE — in the class, you are 'the temporary custodian' of their body.

What this gives you: the shift from 'looking at' to 'reading' a body; and the end of the pressure to learn by rote, so you can concentrate on the few most important structures. [REMEMBER]

Many teachers imagine 'observing the body' is merely the step of correcting a shape while teaching. Wrong. An assessment is a step of systematic EVALUATION that COMES BEFORE any intervention; hands-on adjustment is only the last tool, and not always the one to use.

• The somatic foundation: it is 'using the body's intelligence'. The starting point is kinaesthetic awareness — feeling where the body is in space, and what is happening inside it. The double principle: the teacher OBSERVES, the practitioner FEELS.
• The right order: assess → understand → and only then decide how to correct (with words, with props, or with hands). Correcting before assessing is correcting blind.
• Why it is worth learning: know how to assess and you correct blind far less, and teach markedly more safely and professionally than the teacher who 'corrects whatever they see'.

What this gives you: reset the professional order — ASSESS first, INTERVENE after; and understand why rushing to lay hands on someone is the sign of a person who cannot yet read a body. [REMEMBER]

This is the question that worries so many teachers about legal liability. Engrave the boundary clearly:

• PERMITTED: observing posture, movement and breath; describing what you see in the language of movement ("the right shoulder is higher", "the fold is happening mostly in the back and not yet at the hip"); offering appropriate variations, props and modifications; and monitoring progress.
• NOT PERMITTED: naming a disease ("you have a herniated disc", "a torn meniscus", "grade 2 scoliosis"), diagnosing, or promising to 'cure' a condition. That is the work of a doctor or a physiotherapist.
• The principle of speaking safely: talk about WHAT YOU SEE (the movement, the sensations the student reports), not about A DIAGNOSIS. Suspect a medical problem → collaborate or refer; do not take it on yourself.

What this gives you: the confidence to assess movement without fear of overstepping the law; and ready phrasing for 'describing without diagnosing' when speaking to a student. [REMEMBER]

A movement assessment is not empty theory — it returns three usable things in every session:

• 1. Teaching SAFELY: reading the signs of risk in advance (an abnormal range, a lost axis, a strained breath) so you do not put a student into a pose that is dangerous for their particular body.
• 2. CHOOSING the right work: in the same class, knowing who needs stretching, who needs strengthening, who needs props — individualising instead of 'one mould for all'.
• 3. MONITORING progress: only with an initial observation can you measure change over time — the evidence that makes a student believe you and stay.

One anchoring point about ROM: the range of motion of a synovial joint CAN INCREASE with regular hatha practice — so a low assessment today is no sentence; it is the starting point for improvement.

What this gives you: the ability to sell the value of assessment to a student (safety, the right practice, visible progress), and a reminder to yourself that a restriction is a starting point, not a conclusion. [GRASP THIS]

These are the paired opposites for describing the RELATIVE position of one part against another — the minimum alphabet for noting an observation compactly and accurately:

• Anterior (front) / Posterior (back)
• Superior (above, towards the head) / Inferior (below)
• Medial (nearer the midline) / Lateral (further from the midline)
• Proximal (nearer the root of the limb or the centre of the trunk) / Distal (further away)
• Superficial (near the surface) / Deep; Dorsal (the back of the hand or the top of the foot) · Plantar (the sole of the foot)

A warning that the anatomical sense ≠ the everyday sense: 'the head is superior to the heart' states only spatial POSITION, not importance; and to 'extend the arm' means taking it BACKWARD at the shoulder joint (not 'straightening it out in front', as the everyday phrase suggests).

What this gives you: notes on your observations that are compact and accurate, and can be discussed with a colleague or a medical professional without ambiguity. [GRASP THIS]

Every movement happens within a plane — an imagined two-dimensional slice through the body. The three planes are the filter for classifying every action:

• THE SAGITTAL plane: dividing the body left and right → flexion and extension (Sun Salutations, Downward Dog).
• THE FRONTAL (coronal) plane: dividing the body front and back → abduction and adduction, side bending (Warrior II, Gate pose, Eagle).
• THE TRANSVERSE plane: parallel to the ground, dividing the body above and below → rotation and twisting (every twisting pose).

A terminological note, so you are not confused: some texts call the frontal plane 'coronal', or call the sagittal plane the 'lateral plane' — the same plane under a different name.

The core assessment point: the body is designed to work in ALL THREE planes to stay healthy. When assessing, look for the plane in which a student (or your own lesson plan) is SHORT of movement — a great many people live only in the flexion–extension plane and almost never side-bend or twist.

What this gives you: a three-dimensional filter for detecting 'gaps in movement', and a self-check on whether your plan covers flexion-extension, side bending and rotation. [REMEMBER]

Why does the whole matter so much? Because the body is one continuous fascial network — like the white pith of an orange, wrapping every muscle, bone and organ, and woven through the whole body as ONE net. The consequence: 'movement at one joint NEVER happens in isolation' — every action pulls on the net joining above, below and around the trunk.

• The chain effect: an over-short iliotibial band can produce RESTRICTION at the hip, the lower back or the knee — usually with NO local pain, but with symptoms at another joint. The place of restriction or pain ≠ the place of the root.
• The 'locked-long / locked-short' pattern: hold one hip out of line for long enough and that side thickens and stiffens — the muscle, though LENGTHENED, stays chronically contracted ('locked long') — while the other side is 'locked short' and weakens. The pain is usually felt on the LONG side — but stretching only the painful side further makes it worse; you must OPEN THE SHORT SIDE to find balance.

What this gives you: when you find a tight or painful spot, ask yourself 'what are the joints above and below it doing?'; do not treat the branch. [REMEMBER]

Many teachers only take a snapshot of the standing shape and conclude from it. But the body only reveals the whole pattern of faults and the compensating muscles when it MOVES.

• STATIC observation (standing shape, symmetry, the axis line) tells you the 'starting point' and the obvious structural deviations — necessary, but not sufficient.
• DYNAMIC observation (the range and the QUALITY of movement through a few basic actions) is what shows which joint is 'jammed', which muscle is compensating, and which plane is being avoided. This is where an assessment hits or misses.
• Quality > measurement: do not only ask 'how far can you fold' but 'HOW do you fold' — smoothly or jerkily, evenly on both sides or off, with an easy breath or a held one.

What this gives you: always combine static and dynamic looking; and prioritise reading the quality of the movement, not only the range. [GRASP THIS]

An assessment begins with the EARS, not the eyes. With a student who has an underlying condition, a past injury, or is older, one simple intake conversation is a shield for both safety and liability:

• History & painful regions: old injuries, where it hurts, when it hurts. (Only RECORD it; do not diagnose.)
• The goal: an end to back pain? better sleep? more strength? preparation for birth? — it decides the direction of the whole session.
• Lifestyle & today's state: sedentary or active, mood, sleep — the same person can be different today from yesterday.
• Acute or chronic? Acute pain (a recent fall, a sprain) usually needs rest, and poses in that region avoided or modified. Chronic pain usually needs MORE controlled movement — but if there is any doubt about that boundary, let a medical professional determine it.

What this gives you: a set of first-session questions so you are never 'frozen'; and knowing which region to avoid before handing out a pose. [REMEMBER]

Observe the standing shape from four directions (front, back, both sides): the symmetry of shoulders and pelvis, and the axis line. Two things to examine first:

• A neutral spine: seen from the side there is an alternating S-curve — the cervical arch, the thoracic rounding, the lumbar arch — to absorb shock and keep balance. At ideal neutral, the spine is NOT rotated and NOT side-bent. The common deviations: excessive thoracic rounding (hyperkyphosis) and an excessive lumbar arch (hyperlordosis, a sway back).
• A neutral pelvis — the 'BOWL OF WATER' test: picture the pelvis as a bowl full of water. Neutral = no water spilling. Tipped forward (the bowl spilling forward) → a lumbar arch. Tipped back (spilling backward) → a flat or rounded lower back. The water also spills when one 'hip point' is hitched up. A landmark you can feel: the anterior superior iliac spine (ASIS) is exactly that 'hip point' under the skin — use it to read the tilt.
• The Tadasana body scan: seen from the side, the landmarks EAR – SHOULDER – HIP – KNEE – ANKLE should sit on ONE vertical line. This is the foundation of every standing pose.

What this gives you: two concrete 'rulers' (the S-curve of the spine + the bowl of water at the pelvis) to describe a deviation in words, instead of a vague feeling that 'something looks off'. [REMEMBER]

Have the student do a few basic actions and read the range + the QUALITY: fold forward, extend, side-bend, twist, squat, and raise the arms overhead. Look for: is it even on both sides? smooth or jerky? which plane is being avoided? where is the compensation (raising the arms overhead while arching the back to compensate for a jammed shoulder, for instance)?

• The breath = an objective sign of excessive effort. If the breath is SHALLOW and IRREGULAR, the body is being pushed beyond its means and will grip — a signal to make it LIGHTER until the breath returns to slow and even. This is a 'gauge' you can observe from a distance, with no need to touch.
• Remember joint shape when reading a range: what each joint is 'permitted' to do differs — a ball-and-socket (shoulder, hip) has a large range in every direction; a hinge (knee, elbow) chiefly flexes and extends; and a hinge all but refuses to rotate when it is straight. Do not ask a knee to rotate like a hip.

What this gives you: the breath as an immediate 'safety brake'; and reading a range according to each kind of joint's proper 'authority'. [REMEMBER]

Teachers want practical tools: a few two-minute tests in place of a vague impression. You can do all of this on the mat, with no equipment:

• Palpation: using touch to identify which muscle is working, and whether it is SUPERFICIAL (near the surface) or DEEP. An easily palpated muscle such as sternocleidomastoid (SCM) is the long strap either side of the neck — handy to see and feel when assessing the neck region. Most muscles are grouped by ACTION, so link a muscle to an action you can observe.
• Mini-tests of mobility and stability: a deep squat (ankle + hip), arms overhead against a wall (shoulder + chest), standing on one leg for 20–30 seconds (balance + stability of the standing hip), and sitting in Sukhasana to see whether the knees sit higher or lower than the iliac crest (hip external rotation). Run them quickly at the start of a session to sort the group.
• Ask permission before you touch. Palpation and hands-on adjustment are physical contact — always ask first and respect boundaries.

What this gives you: a pocket set of tests for sorting students and for linking a muscle to an action; and touch with consent. [GRASP THIS]

An observation not written down evaporates after the session. Record it briefly, so as to (a) decide how to teach today, and (b) compare progress next time.

• Record in the language of MOVEMENT, not diagnosis: "folds forward mostly from the back, the pelvis not yet tipping forward, hamstrings tight on both sides" — do NOT write "herniation".
• Use the directional vocabulary correctly, with left and right from the student's side, so that reading it back later leaves no confusion.
• Record the state of that day as well (slept badly, newly injured), because it explains why today was different.
• A reminder about ROM: today's figure is a starting point, not a sentence — regular yoga increases the measurable range of motion.

What this gives you: a minimal 'movement file' for each student; and proof of progress in data, which keeps them with you. [GRASP THIS]

The common misunderstanding: 'wherever is tight, stretch it'. In reality, muscles work in ANTAGONIST PAIRS — one shortens and the other lengthens in response. So very often a muscle is tight because the one opposite it is WEAK or inhibited.

• Reading a hunched or sway-backed posture: the same shape can come from several different combinations of opposing muscles — one side shortened and pulling things out of line, the other lengthened and weak. Stretch only the tight place without STRENGTHENING the weak one and the imbalance only worsens.
• Connecting to 'locked long': the painful, tight side is usually the chronically lengthened one; stretching it further is pouring oil on the fire. You must STRENGTHEN that side and OPEN the short side opposite.
• Why an instruction to CONTRACT a muscle helps it STRETCH deeper: reciprocal inhibition — when one muscle contracts, the nervous system automatically lets the opposite one relax (contract the quadriceps so the hamstrings release themselves in a forward fold). This is a safe tool for 'opening' without pulling blindly.

What this gives you: the shift from 'tight means stretch' to 'find the antagonist pair': stretch the short side and strengthen the weak one; use reciprocal inhibition instead of force. [REMEMBER]

The misunderstanding: 'the more mobile the better'. The truth: students with joint hypermobility ('double jointed') — the most flexible in the class — are usually the EASIEST to injure, and correlate with chronic joint pain.

• Why: the hypermobile usually have poorer proprioception, and their joint pain receptors (nociceptors) are thought to be less sensitive too → making it hard to receive the 'you have reached the limit' signal → so they easily go TOO DEEP, past the tissue's safe threshold, without knowing.
• Ligament cannot contract: over-stretched, it usually does NOT return to resting length → and the joint is left UNSTABLE for the long term (and very hard to recover). The principle: stretch MUSCLE; do not stretch TENDON or LIGAMENT.
• A prescription against the intuition: the very flexible need to concentrate on STRENGTHENING asana and creating STABILITY (co-contracting both the prime mover and the antagonist to lock the joint), and do NOT need more flexibility work. In an assessment you must evaluate STABILITY as well, not only flexibility.

A warning about the setting: high heat (hot yoga) lets tissue stretch beyond its natural length more easily → so the hypermobile overshoot all the more readily. Enter poses SLOWLY and with awareness.

What this gives you: recognise the hypermobile student in order to protect them from their own flexibility; and prescribe strength and stability work rather than praising 'how flexible you are'. [REMEMBER]

This is the centre of a standing posture assessment, linking straight to the 'bowl of water' in the process:

• The spine — examine all four directions of movement: a healthy spine needs to move into and out of all four — forward flexion, extension, side bending and rotation. In an assessment, check whether the student uses all four or is accustomed to only one. The flexibility of the whole spine is the SUM of many small movements at the intervertebral joints.
• Pelvis and hips: read the tilt with the bowl-of-water test through the ASIS landmark. Tight hamstrings are the most important observable sign in a forward fold: they pull the pelvis into a POSTERIOR tilt → the lower back loses its curve and rounds (most clearly seen in Downward Dog and a seated forward fold).
• Normal versus noteworthy: normal = a neutral pelvis, the back keeping its curve while folding at the hip. Noteworthy = the back rounding the instant they fold forward, with the pelvis 'locked' in a posterior tilt.
• A self-check: sit with the legs straight and fold forward — if the back rounds at once and the hands do not reach the feet, try sitting up on the edge of a block; if the back straightens again → the limit is the hamstrings and the pelvis (tension), not the spine.

What this gives you: telling 'a rounded back from the pelvis' apart from 'a problem in the spine'; and knowing at once that the solution is to raise the seat. [REMEMBER]

The knee and the ankle usually 'carry' the consequences of a fault elsewhere — in the true spirit of the kinetic chain:

• The knee is a HINGE: chiefly flexion and extension, with very limited rotation (above all when straight). The noteworthy signs: the knee 'falling inward' in a squat or a lunge, or the knee travelling past the toes in a bent-knee pose. The universal preventive cue: 'knee tracking over the toes'.
• The root is usually above or below: knee pain often originates at the ANKLE (rolling inward) or the HIP (weak stabilisers) — examine the whole chain instead of fixing your eyes on the knee.
• The foundation of the foot: place the weight through three points (the ball of the big toe, the outer edge, the heel) and lift the arch. The ankle has dorsiflexion (drawing the top of the foot up — Downward Dog) and plantarflexion (pointing the toes). A dropped arch or a stiff ankle pulls the whole chain above out of line.
• A self-check: squat deeply with both heels on the floor — if the heels lift or the knees fall inward, check the ankle (dorsiflexion) and the hip before 'blaming' the knee.

What this gives you: protecting the knee with an axis cue, and tracing the root up to the hip or down to the ankle; and reading the foundation of the foot as the footing of every standing pose. [GRASP THIS]

Having assessed, you must make a DECISION, or it was only 'having a look'. Three ways to correct, in order of priority:

• 1. Correct with WORDS (a verbal cue) first: in most cases one reminder is enough for the student to correct themselves. Keep the cue SIMPLE and clear, and do not call out muscle names — you only need to KNOW why that cue helps. For example: 'find the natural curve of the spine', 'knee tracking over the toes', 'sit right on the two sitting bones'.
• 2. Props, matched to the restriction you found: tight hamstrings or pelvis → a BLOCK under the hips in a seated forward fold, so the pelvis tips forward and the spine straightens again; the floor out of reach → a block under the hands; a strap round the foot to deepen the stretch; a wall or chair to support balance and give the sensation of correct alignment.
• 3. Hands-on — with care, and with permission: only when words and props are not enough, and ALWAYS asking first. Remember: what you take for 'wrong' is sometimes the body ADAPTING to its own structure or an injury — and correcting it then does harm. When in doubt, do not touch.

What this gives you: a clear ladder of intervention (words → props → hands); and every restriction you find attached to a concrete solution. [REMEMBER]

Assessing well also means knowing when to STOP and bring in medical expertise. This is the part that protects both the student and you:

• Signs of over-stretching — STOP AT ONCE: a sharp or electric pain, numbness, or anything that makes the student grimace or hold their breath. A proper stretch is felt in the middle of the muscle belly with the breath still easy.
• Refer on when: you suspect a condition needing diagnosis (spreading pain, lasting numbness, an acute injury, neurological signs); there is an underlying condition needing medical supervision; or at any point beyond your ability to assess. Say something like "I think you should have this looked at professionally to be sure", and do NOT name a disease yourself.
• Respect the body protecting itself: an 'off line' detail may be a necessary adaptation — not everything that differs from the textbook needs 'correcting'.
• Entering a pose SLOWLY and with awareness is always the safe default — above all with the hypermobile, with beginners, and with anyone recovering.

What this gives you: a list of 'red flags' for stopping or referring at the right moment; and staying inside your scope of practice, out of harm's way. [REMEMBER]

• 1. An assessment ≠ hands-on work: it is a step of systematic EVALUATION that COMES FIRST; the teacher observes, the practitioner feels. [REMEMBER]
• 2. The professional boundary: observing and assessing movement and offering variations is PERMITTED; naming a disease BREAKS THE LAW — refer them on.
• 3. The reference markers: know 'normal' (the neutral position, the directional vocabulary, the three planes) before you can see 'off line'; and left and right follow THE PERSON BEING observed.
• 4. The whole before the detail: the body is a continuous fascial network — the painful place ≠ the root; read the whole chain, combining static and dynamic observation.
• 5. The five-step process: Ask → Static observation → Dynamic observation (the breath as the brake) → Palpation & mini-tests → Recording.
• 6. Three reversing insights: compression (bone, uncorrectable) differs from tension (muscle, correctable); the tight place is usually not the culprit — strengthen the weak side opposite; and the most flexible need STABILITY, not more flexibility.

The practice exercise: observe one person you know standing and walking, then write down three things you saw — in the language of movement, NOT diagnosis. The closing line of the profession: a good teacher is not the one who corrects the most but the one who can READ a body before laying a hand on it. [REMEMBER]
