Coordination of the Flexor Muscles and of the Extensors (Patrons)

Lying on the back, knees bent, one or both feet standing, variations on tilting crossed legs and "triangle" arms/shoulders in order to twist and untwist the torso, learning more awareness, control, and coordination of the major flexors (folding muscles) and extensors (arching muscles).

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 – 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 – 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 – 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 2 – Social Sharing

Project tip: Try the social buttons below. Please help us to achieve our vision: spreading the life-changing benefits of Feldenkrais study as widely as possible!

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 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 – 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 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.

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 – 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 – Lesson names

What’s in a lesson title? Lessons are about an hour unless a shorter duration is shown in the title. Thanks to our donors they’re freely offered unless marked “Patrons” – those are how we thank our Patron-level donors.

Tip – Join!

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 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.

If you struggle with the legs crossed, knees tilting configuration and movements used frequently in this lesson, you might instead do one of these first: Legs as Free as a Baby’s, or Folding, Foundation, and Feet, or The Hip Joints: Moving Proximal Around Distal. They will help improve the hips and lower back and make this lesson more accessible.

It’s helpful to have a very secure place for the foot stand when the legs are crossed closely together. Consider options to create more friction.

flexext triangle photoThe triangle arms position described around 11 minutes into the lesson has the arms extended toward the ceiling (elbows straight but not locked) and palms “glued” together. The arms and hands are thus in the air “right in front of the breastbone at the height of the shoulders,” like so:

Some might wonder what a lesson primarily using twisting and untwisting movements has to do with the flexor and extensor muscles, which are usually only thought of as folding the body forward and arching it backward in the plane of front-back movements (the sagittal plane). These muscles are also involved in very refined ways with twisting, because twists also change the lengths of the front and back, and both lengths must be carefully regulated to control the twist, especially when gravity is a factor in this lying down configuration. By asking students for the careful control necessary in this lesson they’re prompted to learn a lot more awareness of this fine coordination between the flexor and extensor muscles.

This lesson is one of 12 in Moshe Feldenkrais’s 1972 book Awareness Through Movement. The Feldenkrais Project has a collection of lessons from this source.

It was taught in the context of a Feldenkrais Fundamentals class which was designed to be a practical study of Moshe’s Awareness Through Movement book. Study tips for the book are here, along with info about where to get it.

    This is great! I was taking an Awareness through Movement class in The Villages last fall & loved it, but the instructor became very ill & there’s no one to teach the classes anymore. Finding your website is wonderful!

  2. Flavia on August 30, 2018 at 12:56 pm

    This lesson stops at the 16:32 minute. 🙁

      I wasn’t able to recreate this problem. You may have had a momentary internet outage, or perhaps it was a hiccup on my end. Please do let me know if it happens again. In the meantime, rebooting your browser fixes any technical issues people have had with my site about 99% of the time! Thanks for listening.

    Hi Nick, I want to thank you for your ATMs. I live in Australia and although there are many felde classes and practitioners available, I enjoy your classes more than any I have attended locally. Your clear instructions and reminders are easy to follow, and it is so convenient to login and choose something that feels relevant to what I need at any given time. Once again, thanks.

    I too am in Oz, and love Nick’s lessons. I’ve learned from some very good people, and have done a number of variations of this lesson. Nick’s directions are such that i keep discovering new movements, mobilities and connections. When i get up and walk around, all my joints feel OILED!

  5. Lorraine on April 9, 2021 at 1:08 pm

    I love this lesson. Your presentation is faithful to the original. Nevertheless you bring something more to the presentation. I am grateful to Moshe for developing and sharing his insights but aware that we have learned even more in the intervening years and a classic lesson makes this clearer to me.

    WoW what a great lesson!!

    My head kept getting further up the floor.Jean Kirk.

    The word that came to mind at the end was “integrated.” I felt like I was more connected head to toe. I also felt like I’d had a workout!

    I enjoyed this lesson for many of the same reasons I enjoy a lot of them: I feel like it increases the fluidity and articulation of my torso, ribs, scapulars, etc., which have been somewhat “frozen” as a result of injuries that have accumulated as I have used my body pretty hard (white water canoeing, dancing, running, hiking, working out) and aged (now 62). Also, I love that you remind us to look for the pleasurable feelings in movement because we are already very good at focusing on the painful ones. It’s like letting my body remember how joyful it used to feel, and finding those sensations again. To me this is the greatest “gift” of the ATMs and the way in which your narration guides me through them.

    It’s interesting that in this particular narration you keep reminding us that we may not need to use the lumbar arch and can instead let the weight into the floor relax and strengthen our movements. I didn’t find my lumbar region had any desire or tendency to arch, but I did notice that I had to keep returning some attention to my jaw to keep it relaxed during the head-lifting parts of the sequence.

    • Gertrude Schmidt on August 31, 2024 at 7:39 am

      The lumbar arch and region around my sacrum had been the most vulnerable part of my body till last year, somehow I found the key to solve my problem.

  10. Wendy Hoben on August 18, 2024 at 1:22 pm

    P.S., I am in Berkeley, CA, not Oz, but want to echo others that Nick’s narrations/interpretations of ATMs are an order of magnitude better, clearer, and deeper, than any I’ve encountered in the the four or five other practitioners I’ve tried. I also really like doing them on my own time, in my own space. Often I listen to a new ATM first as I’m in bed getting ready to sleep, going through what it would probably feel like mostly in my mind. Then, if it seemed interesting, as most do, I do it “for real” (i.e., not in bed) a day or two later. This seems to help me avoid the tendency to “strive” too hard when I actually do the ATM because I’m already more attuned to seeking the nuances of the movements. Recently I had a short series of hands-on one-on-one sessions with a very good local practitioner to help me problem-solve some specific issues and after each session I found one or more of Nick’s ATMs that perfectly complemented the one-on-one sessions.

    Lovely lesson, I always enjoy the proprioceptive experience of twist lessons. I usually try not to give words to the sensations, but considering the class was asked to at the end I figured I’d give it a go, the closest I can come is feeling “lighter”.
    The judo remarks made me remember something from my youth I hadn’t thought of in a long time. I did judo from age 7 to 14, and as a teen one time I fell head first from quite high onto concrete, something that should’ve caused severe damage. I had and have no recollection of the actual fall, but bystanders saw me break the fall smoothly (in their words “you did a judo roll”) and I was completely fine. Thinking about that now I feel like it’s a great example of sensorymotor learning at work. No conscious cognitive effort was needed to put into practice the motor skills I’d acquired during my years of judo, the body just automatically knew what to do without any conscious decision making. So it doesnt pertain to the contents of the lesson perse, but jjst that remarks triggered a great reminder to me as I recover from chronic illness, that I can trust in my body’s capacity to organise itself.

    • Catherine WHITE on September 17, 2024 at 11:58 am

      I appreciate your insights on your Judo experience when you fell, and the relationship to practicing Feldenkrais. Sometimes I wonder if I need to put effort into my everyday movements to maintain what my body learned in an ATM lesson . Your comment reassured me that I can trust in my body’s wisdom, while embracing my surprise moments of awareness when they show up!
      Thank you, and thank you Nick!

    The differentiation in this lesson is incredible. I have been unwinding scoliotic patterning for the last 8 or so years, and I notice a LOT of stiffness in my rib basket, shoulder girdle, and lower back. It is interesting what I have learned about my body from these lessons, and I am finally at the point where I can do this kind of mid twisting and it helped me learn so much!
    Feldenkrais helped me notice that I was chronically bracing in my left hip, which I had no idea I had been doing. In this lesson I was very aware of how I would press my feet into the floor and activate the hip to counterbalance or compensate for the twists, and I was able to continually relax the left hip and intentionally press my right foot into the ground instead to play with it and see what happened. Curious if I can change my brain so I’m giving it a try! Thanks!

    Great lesson! I noted in the first part, while tilting the legs, that it is possible with only using the foot (without using the belly muscle) and also vice versa. The aim is probably a mixture of both, right? I am someone with not much sense for what muscle is sensible to use, so I am somewhat lost, if there is no explicit instruction what muscle to use (although I understand, that it is one of the main points of Feldenkrais lessons, to figure out by oneself).

    • Nick Strauss-Klein on September 1, 2024 at 9:28 am

      It’s true we almost never “target” specific muscles, because that’s not how spontaneous movement happens, feels, or is regulated as we live our lives normally. At the very beginning of the leg tilting it may be that your movement was so small that you could tip and return the legs just by manipulating the edges of your foot. But after the knees have moved more than a couple inches, you actually have to use core muscles to return them to balanced. That’s the physics of it, but you may not have found awareness of this engagement yet. It may be helpful to follow skeletal landmarks closely: the relationship of your sacrum to your ribs on either side of your back, for example.

      As you said at the end, it’s not necessary that you “figure it out” consciously in order to improve.

    🙏 My body remembered ,with pleasure, doing this lesson from 40 years ago !
    Nick’s delivery was a beautiful – helping me to return to sensations of joy , balance and strength , that have been buried beneath many years of stress and tension. My spine feels looser and longer now and my left hip joint , which has been bracing forward for years, feels way more relaxed. .
    Thank you 🙏
