Flexibility as a Liability: What Circus Teaches Us about Hypermobility w/ Dr. Emily Scherb (Ep 210)

What if being “naturally flexible” is actually the thing putting you at risk for injury?

Dr. Linda Bluestein welcomes back Dr. Emily Scherb, known as The Circus Doc, for a fascinating conversation about what circus performers can teach all hypermobile people about flexibility, strength, joint control, and injury prevention.

A physical therapist, researcher, and former circus performer, Dr. Scherb explains why being able to get into an extreme position is not the same as being able to control it—and why impressive range of motion can sometimes mask weakness, instability, or poor load tolerance.

The conversation explores how hypermobile bodies function differently at end range, why building strength in the mid-range can be so important, and how to tell the difference between normal training soreness, overtraining, injury, and signs that may point toward an underlying connective tissue disorder.

Dr. Scherb and Dr. Bluestein also dig into the psychology of pushing through pain, the way flexibility can become intertwined with identity, the spinal changes documented in contortionists, and why performers may hide injuries when they fear that speaking up could threaten their careers.

And while circus provides an extreme example, the lessons apply far beyond the circus world—to dancers, athletes, yogis, gymnasts, and anyone with a body that moves farther than average.

Takeaways:

More range is not always better. Hypermobility describes how far a joint can move; what matters just as much is how well you can control that range.

Getting into a position is not the same as owning it. Extreme flexibility without adequate strength and control can increase stress on joints and surrounding tissues.

Hypermobile people often benefit from building strength and motor control in mid-range before progressively challenging end range.

Persistent pain, recurrent injuries, instability, or symptoms that seem disproportionate to training may be clues that something more than routine soreness is going on.

Contortion offers a striking example of how repeated end-range loading can produce measurable adaptations in the spine.
