Yoga Anatomy

Yoga Anatomy: How the Practice Works in the Body

A cue like "engage your core" or "relax into the stretch" is only useful if you know what is actually happening under the skin. Yoga anatomy is the study of that: which tissues a pose loads, why a hamstring stays tight after years of forward folds, and what the nervous system does when you slow the breath. These guides are written for people who want the mechanism, not the metaphor.

Who these guides are for

Practitioners read them to understand their own bodies: why one hip opens and the other does not, or why a long exhale calms them down. Teachers read them to cue with precision and to stop repeating anatomical claims that do not hold up. Both benefit from the same rule we apply throughout: name the structure, describe what it does, and cite the research where it exists.

I write these as a teacher first. The physiology is there to serve the practice, and where the science is still unsettled, the guide says so.

How the yoga anatomy guides are ordered

The first three deal with tissue. Fascia comes first because it changes how you read everything else: connective tissue is continuous, and a restriction in one place shows up somewhere else. The hamstring and hip flexor guides then take two of the most common complaints in a yoga class and explain what is actually limiting the range, and what to do about it.

The last two move to the nervous system. The parasympathetic guide explains what "rest and digest" means physiologically and how yoga practices act on it. The polyvagal guide goes further into the vagus nerve, the theory around it, and how it is used, and sometimes overused, in yoga and breathwork teaching.

Start here

1. What Should Yoga Teachers Know About the Fascia?: what connective tissue is, how it behaves, and why it changes how you cue.
2. Why Are Your Hamstrings So Tight in Forward Folds?: the real limits on hamstring range and how to practise around them.
3. Hip Flexor Muscles and Yoga: What You Should Know: the psoas and its neighbours, and the poses that load or lengthen them.
4. The Effect of Yoga on the Parasympathetic Nervous System: what the rest-and-digest branch does and how practice acts on it.
5. How Polyvagal Theory Influences Yoga and Breathwork: the vagus nerve, the theory, and how it is applied and misapplied in teaching.
