The Hypermobile Student Who Feels Nothing
A 29-year-old regular student has practiced for two years and can fold forward with palms flat, hyperextend elbows and knees, and drop into full wheel without warm-up. She demonstrates about 120 degrees of knee hyperextension and can touch her palms to the floor with straight legs. She says she feels "nothing" in hamstring stretches and likes to go deeper; after class she reports a dull ache at the sacroiliac joint and "clicky" knees. She asks you how to "feel the stretch" and whether she should push through the end range. She attends four vinyasa classes per week and one power class. She has no known diagnosis, no imaging, and no pain during class. You have a 60-minute class with 16 students, and she wants to keep up with the advanced options.
1. How do you answer her question about "feeling the stretch" and pushing through end range?
Read the worked answer
I would explain that "feeling nothing" in a hamstring stretch may reflect joint end-range rather than muscle lengthening: her ligaments and joint capsules are taking the load while her muscles are not. Pushing past end range trains tolerance for passive range, not strength or control, and can aggravate the SI joint and knees. I would shift the goal from sensation to control: bend the knees in forward folds, activate the hamstrings and quadriceps, press the thighs toward each other, and use a strap to keep the spine long.
The cue is "find the point where you can still contract, not the point where you can go furthest." I would not promise that she will feel a stretch; some people need strength and proprioceptive work first. This respects her autonomy while reframing what progress means.
2. What pose choices and sequencing changes would you make in class?
Read the worked answer
In a mixed class I would keep the sequence but offer a "stability track": micro-bent knees in standing forward folds, blocks under hands, no locked elbows in Downward Dog, and a shorter lever in Plank. For backbends, I would emphasize rib control and gluteal engagement rather than dropping into full wheel; wheel can be optional at the wall with bent elbows and active legs. I would reduce prolonged end-range hip flexion and avoid deep seated forward folds with straight legs.
I would add strength work: chair pose, bridge, bird-dog, and standing balance. For the SI joint ache, I would avoid asymmetrical deep lunges if they reproduce symptoms, and offer a supported constructive rest. The reasoning is to load muscles in mid-range and build proprioception rather than reward maximum depth.
3. When would you refer, and what language would you use?
Read the worked answer
I would refer if she reports joint pain that persists after class, swelling, giving way, numbness, or a family history of connective-tissue disorder, or if she has had recurrent subluxations. I would not diagnose hypermobility spectrum disorder or Ehlers-Danlos syndrome; I would say, "The way your joints move is worth having a clinician or PT assess, especially because you are getting ache and clicking."
I would ask whether she has been evaluated before and document that I suggested it. I would continue teaching her with modifications unless a clinician restricts activity. The judgment is to avoid both normalizing joint pain and alarming her; the referral is about persistent symptoms and the value of an expert assessment, not about a label I cannot give.
