Pose libraries, books and apps usually organise poses in one of two ways. Some group them into families based on the shape of the pose: standing poses, seated poses, twists, backbends, forward bends, inversions. Others group them by muscle group or body area, such as hamstrings, shoulders or hips.

Both are useful, but they answer different questions. This guide explains the difference and how to use each when planning practice.

Pose families: organised by shape

A pose family groups poses by what the body is doing as a whole. Common families include standing poses, standing balances, seated poses, forward bends, backbends, twists, side bends, hip openers, arm balances, inversions, reclined poses and restorative poses. Exact lists differ between traditions and teachers.

Families describe the movement of the spine and the base of support. Knowing a pose's family tells you a lot about its setup and what it asks of you: standing poses need a stable base on the feet, twists rotate the spine, inversions put the head below the heart.

  • Useful for: building a balanced session, choosing counterposes, understanding sequencing.
  • Useful for: safety screening, because cautions often apply to a whole family, such as inversions.

Muscle groups: organised by body area

Grouping by muscle group or body area lists poses that are commonly felt in, or commonly said to work, a region: the backs of the legs, the shoulders, the hips, the core. This is how many people search, because they notice a particular area feels tight or want to strengthen it.

  • Useful for: finding several poses that involve an area you want to focus on.
  • Useful for: noticing that one body area is missing from your practice.

Why 'targets' labels need care

Muscle-group labels are approximations. Most poses involve many muscles at once, some working to hold you up and others lengthening. Where you feel a pose also varies between people, and a category cannot establish the cause of an individual sensation. A pose labelled as a hamstring stretch may be felt mostly in the calves or the back of the knee by someone else.

Treat a body-area label as a starting point for exploration, not a promise of an effect. Labels such as 'detox', 'tones' or 'fixes' go further than a pose description can support.

Comparison at a glance

The two systems are complementary; this summary shows which question each answers best.

  • Question answered: family tells you what shape the pose is; muscle group tells you where it is commonly felt.
  • Planning a session: family is better for balance across movements.
  • Finding options for one area: muscle group is faster.
  • Safety cautions: check the individual pose and your circumstances, not the family label alone.
  • Precision: family is objective about shape; muscle group varies between people.

Using both together

A simple planning routine uses families for structure and body areas for emphasis.

  1. Pick your session's families first, for example standing, seated forward bend, twist and rest.
  2. Within each family, choose a pose that also involves a body area you want to include.
  3. Check the pose's cautions and your own comfort.
  4. Add a counterpose from a different family where useful.
  5. After practice, note where you actually felt each pose; this records your experience, not a measurement of which muscles were working.

A note on safety

Neither family membership nor a muscle label makes a pose suitable or unsuitable on its own; individual circumstances matter. The US National Center for Complementary and Integrative Health lists conditions such as knee or hip injuries, lumbar spine disease, severe high blood pressure, balance issues and glaucoma as reasons poses may need modifying, and advises discussing individual needs with health care providers and instructors.
