The Hypermobile Client Who Can Do Everything

She is half right, and the half she is wrong about matters.

Her mobility scores are uniformly high - three 3s - so she is correct that mobility is not her limiting factor. The two 1s are on the two screens that ask the trunk to stay still while the limbs move: the trunk stability push-up and rotary stability. Those are not strength tests in the usual sense, and this is where her framing goes wrong. "Getting stronger" in the gym sense - more load on a barbell - will not automatically fix a trunk that cannot hold a rib-down position under bodyweight.

Why the 3s deserve suspicion rather than congratulations. A 3 on the deep squat or the active straight leg raise means she met the criteria on that day. In a hypermobile person, end range is cheap: ligamentous laxity lets her reach the position while the load is carried by passive structures rather than by controlled muscular tension. The screen cannot see the difference between a squat she owns and a squat she falls into. Her screen therefore understates the problem, because she can always "get there".

What the 1s mean. They say the trunk cannot maintain position while the limbs move, which is exactly the control that protects a hypermobile joint at end range. They are a movement-quality flag, not a diagnosis and not a prediction of injury. There is no pain and no positive clearing test, so nothing here needs a medical referral - the intervention is control, not treatment.

The hidden variable. She teaches ten classes a week and spends hours demonstrating end-range positions. Her daily dose of end range is enormous, and no amount of correctives will out-train it. Any plan has to include how she demonstrates, not just what she does in the session with you.

What they measure. The trunk stability push-up is not a chest and arm test. With the hands narrowed to the forehead or chin, the lever of the upper body gets longer, and the only way to complete the rep without the hips dropping or the low back arching is to stabilise the trunk before the limbs move - the sequencing of proximal stiffness ahead of distal motion, plus the reflex stabilisation that holds the rib cage and pelvis together. Rotary stability is the same quality in a diagonal pattern: quadruped, opposite or same-side arm and leg moving while the trunk resists rotation and the pelvis stays level.

Exercise 1 - dead bug with a heel slide. Supine, knees over hips, ribs down. Slide one heel out while the trunk stays completely still, breathing throughout. Faults: rib flare, breath-holding, the low back lifting off the floor, and speed. Regress by shortening the lever and reducing the range.

Exercise 2 - bird dog with a dowel on the back. Quadruped with a dowel along the spine, contacting head, thoracic spine and sacrum. Lift the opposite arm and leg a few centimetres and pause. Faults: the dowel rolls or loses contact, the pelvis drops on the lifted side, the shoulder shrugs, and range creeping to end range because she can.

Exercise 3 - half-kneeling Pallof press with a very light band. Anti-rotation, with an exhale into the press. Faults: the trunk rotating towards the band, weight shifting off the down knee, and the ribs flaring as she presses.

Common thread: short levers, small ranges, slow tempo, and a breath she has to keep. Progress by lengthening the lever, then range, then speed, then load - in that order. For her specifically, do not progress range until the position is held with the breath intact.

The trade-off. The goal is stiffness on demand - enough tension to control a joint through a task, applied when needed and released when not. Rigidity is tension applied all the time, globally, with the breath held. In a hypermobile client, rigidity is tempting because it produces an immediately "better-looking" rep: everything stops moving. But it substitutes a global hold for genuine control, it is not available under fatigue or in unpredictable positions, and it usually comes with a breath-hold that degrades both performance and the sense of safety.

Cues that build stiffness without rigidity:

• "Breathe out as you move; if you can't speak a short sentence, you're working too hard."
• "Keep the rib cage stacked over the pelvis - don't let the ribs lift."
• "Reach long rather than grip."
• "Turn the dial a little, not the switch."
• "Stop at the point where you could still breathe normally."

Avoid "squeeze everything", "brace like you're about to be punched", and "squeeze your glutes hard" - all of which she will over-apply instantly.

How I know it is working: she holds five controlled reps in the same shape with the breath unbroken; there is no rib flare on video; there is no low-back tightness afterwards; and she can still do the movement after a short distraction, which shows it is owned rather than rehearsed. The confirmation is the retest: the trunk stability push-up moves from 1 to 2 with the hands at the chin and no lumbar lag.

How I know it is wrong: the rep looks rigid, she stops breathing, she reports feeling "tight" in the low back or neck afterwards, or the exercise falls apart the moment the load or speed changes. If more effort makes the movement worse, the cue is the problem.
