Reaching Distinctions: Flexion or Extension? (Patrons)

Prerequisite: Familiarity with either the short or full-length Long Belly, Strong Back lesson is helpful for this lesson.

The classic "Arms Like a Skeleton" lesson is the framework for a quiet exploration of functional options hidden in everyday actions. When you reach into the world, do you fold or arch (flex or extend)? How do the two sides of your body participate differently? What do you do with your neck? The answers depend on the situation, and a more supple thoracic area expands the possibilities. Eventually your Long Belly, Strong Back learning comes clearly into play.

Before you begin read this for practical tips and your responsibilities, and check out Comfort & Configuration below.

Recorded live in a Feldenkrais Awareness Through Movement (ATM) class, this lesson is copyright Nick Strauss-Klein, for personal use only.

Tip – Got Questions?

Questions? Am I doing it right? How do I study if I don’t have an hour? How often should I study? I can’t get comfortable – what should I do? See our FAQ!

Tip – skip a lesson

Study tip: If you can’t find a comfortable way to do the initial movements or configuration of a lesson, it’s ok to skip it for now and go on to another lesson.

Tip – Comments

Project tip: Leave a lesson comment below! It’s a great way to give feedback or ask a question, and it helps google find us so we can achieve The Feldenkrais Project’s vision!

Tip – Technical Difficulties

Tech tip: If you have any trouble with the audio player, reboot your browser. That solves most issues. If not, try another browser or contact us.

Tip – How to find lessons

How to find lessons and courses: Use the checkboxes and advanced options on our Lesson Search to apply powerful filters. Alternatively, try Searchable User Comments or our Birds Eye View.

Tip – Complete the Movement

Study tip: Complete one movement before beginning the next. You’ll improve faster if there’s enough time between movements that you feel fully at rest.

Tip 3 – Head Support

Study tip: It helps to have a large bath towel nearby when you start a lesson. You can fold it differently for comfortable head support in any configuration.

Tip – what to wear

Study tip: Wear loose, comfortable clothes that are warm enough for quiet movement. Remove or avoid anything restrictive like belts or glasses.

Tip 2 – Social Sharing

Project tip: Try the share button near the lesson title above, and help us on our mission to spread the life-changing benefits of Feldenkrais study as widely as possible!

Tip 5 – Discomfort

Study tip: If a configuration or movement causes any increase in discomfort, or you feel you just don’t want to do it, don’t! Make it smaller and slower, adapt it, or rest and imagine.

Browser/device size and audio player

Tech tip: On mobile or tablet? Once you start playing the audio, your device’s native playback controls should work well.

Tip – What’s New

What’s New? At the bottom of our homepage you can find all our news, newest lessons and courses, and current comments, questions, and discussions with listeners.

Tip – Pause the recording

Study tip: If you’re really enjoying a movement and want to explore longer, or you just need a break for a while, pause the recording!

Tip – LESSS is more

LESSS is more: Light, Easy, Small, Slow, & Smooth movements will ease pains and improve your underlying neuromuscular habits faster than any other kind of movement, no matter who you are or what your training is!

Tip – Lesson names

Lesson access: Thanks to our donors, our lessons are freely offered unless the title ends with (Patrons) – those are how we thank our Patron-level donors. Lesson duration: If you don’t see a duration listed with a title, it’s a regular hour-long class.

Tip 4 – Padding

Study tip: Comfort first! Carpeted floors usually work well, but it’s great to have an extra mat or blanket nearby in case you need a softer surface in some configurations.

Tip – Join!

Join the Project! Members and Patrons see streamlined lesson pages, enjoy My Journey (marking lessons played  saved  and “faved” ), and can access the Related Lessons tab below.

Tip – Directions are Relative

Study tip: Directions are always relative to your body. For example, if you’re lying on your back “up” is toward your head, and “forward” is toward the ceiling.

Tip – Rewinding

Study tip: Many instructions are repeated. If you get a little lost, rest and listen. You’ll often find your way. Or use the rewind button on the page or your mobile device.

Tip 1 – Interrupted?

Study tip: Interrupted or don’t have enough time? You can return to the lesson later today or tomorrow. Read how best to continue your learning on our FAQ page.

It’s helpful to use only the minimum head support you need for comfort, and it should be very smooth so your head is free to roll, nod, or even slide a little.

“Homework” after this lesson could consist of carefully observing the movements of your shoulder blades, ribs, spine, and hips in everyday life, especially in the minutes and hours immediately following study. When are you flexing more/turning more/extending more as you reach into the world? Can you also notice elements of side-bending in some reaches?

Pleasant, efficient, and effective action is immediately available if the spine and thoracic bend and reshape themselves easily as we interact with the world. Reaching is a joy when we’re not limited to compulsive or rigid carriage of our torsos.

In discussion after class one student remarked that in “saying yes to flexion” she found an opportunity to work with and release patterns of fear which had been troubling her recently. She found herself surprised that it eased so much by the end of the lesson. We talked about how going into a pattern, deeply and patiently and in detail, affords us more control of it.

On another note, this lesson and most “arms like a skeleton” lessons typically limit the reaching vector to only plumb in gravity: reaching directly forward toward the ceiling, with the arm vertical. But, by sensing different combinations of flexing, extending, and turning as you reach, you’re actually learning to reach in all kinds of directions.

This lesson is found in Patron Treasures, our collection of lessons exclusively for Feldenkrais Project Patron-level donors.

It also appears in our Action Heroes: Spine, Hips, Sternum, & Scapulas Deep Dive, and has connections to Grounding for Liftoff, too.

It was recorded in The FP Weekly Pay-What-You-Can Class on September 30, 2025.

    This lesson was transformational for me – thank you.
    I have Ehlers Danlos and in an effort to find stability my ribs and thorax have been stuck in a state of braced flexion whenever I am vertical. At times the flexion can be so severe it can be hard to take a full breath. No matter how much ‘breathwork’ I try, it only seems to exacerbate it. But by leaning into the coordinated flexion and exhalation here, it allowed a subsequent passive expansion and softening of the ribs I haven’t felt in about 15 years. It really did unlock something deep in my brain! Thank you.

      Fantastic! You may have seen in the Curiosities tab above that another person reported a related kind of change with “saying yes to flexion.” It’s one of the secrets of Feldenkrais: we’re not afraid of our patterns. We look into them deeply, and through sensitivity, kindness, and patient process we learn more control, and the ability to find other options of organization and ways of being.

    So valuable. I can get back pain ( iliac crest area) from unintentionally “hyperextending” my back when doing some strengthening exercises (the term hyperextending my back is now confusing to me because it is really more of a contraction of my lower back muscles and isn’t that really a kind of flexion?!)… anyway distributing that arch to include my upper back takes the pressure off my lower back. This helped me visualize that better– how to arch back in a healthier way

      Amen to distributing functions (like arching) throughout our whole spines and selves! It is always a helpful strategy. Your question about what is extension and what is flexion is great! I think you mean “contraction” when you’re talking about flexing the muscles of your lower back, which are extensor muscles.

      Here’s one way to think about it. Since muscles can only contract and decontract, I think of flexion in terms of folding and unfolding the body, and extension in terms of muscles that support or lift the body, and can also rest from that. It’s a slightly more sophisticated and functional way to think about the constant balancing our brains are doing between our flexors and extensors, instead of the more simplistic agonist/antagonist model of flexion and extension.

        Perfect. Thanks. For the info and the great lessons.
