    When I play Xbox with my freind he lays down on his stomach and literally massages his head with the toes of his feet, he also takes his dogs toy and play with it in his foot... he literally holds the ball with his foot and just plays Xbox and holds a ball with his toes and stuff, It’s pretty scary...

    Ok let me correct
    No there is nothing different about sofie
    She started contortion when she was little
    Like me I do contortion
    And there is nothing different about me
    You can do contortion you just need to practice 🤗

    Beighton score has been superseded by other wider hypermobility criteria because you can be hypermobile without scoring anything on the test. First check out the Brighton criteria (yes, the confusing similarity in spelling is real, that's not autocorrect) but even that is limiting. Hypermobility is more nuanced than Beighton scale can show. If you think you have it don't be put off by Beighton score, look up hEDS and hypermobility spectrum. It can take a very long time to be diagnosed mostly because of awareness and partly because of rigidly (!) sticking to the Beighton score as only indicator.

    • Dev Lunsford
      Dev Lunsford 14 days ago

      It's a good thing to mention in passing for the purposes of this video, my comment is mostly for people who think they're on the hypermobility spectrum but Beighton tells them they're not.

    Not shure it's good when you get older and heavy. I was a double black belt kung fu and karate. Training since i was 15 , im now 62 .at one time i could do anything Chuck Norris did . Splits, putting my feet behind my head, Now i have spine and disc problems, Knees have be operated on , it's hard to walk . I Loved doing martial arts. Now I spend most of my day it a chair. Take muscle relaxers at night......you know what ?.......I would do it again , I had so much fun doing karate and kumg fu.

  • John Rhodes
    John Rhodes 15 days ago

    I sit in a squat to stretch everything but my thoracic spine/chest. Then I stand up raise palms to ceiling and try to push finger tips as far apart as I can, raise chest and pull face back (double chin). Find a hamstring stretch you like. Sit on the floor and feet up on couch and do deep breaths for 5 minutes. My spine resets and I feel a lot better after the deep breathing.

    I need to look at that study. I've been getting cramps and kinks from moving without stretching. I hope it has some good stretches and effectiveness in there.

    Hyper-mobility is a pathology and makes joints unstable.

    • Keenan Schouten
      Keenan Schouten 13 days ago

      @Kelli Atkins Ligaments and tendons hold joints in a stable position using tension. The looser they are, the less stable the joint is because deformable structures don't transmit force well. People need just enough flexibility for "normal movement."

    Awesome video! :)
    What hasn't been pointed out is the myofascial connections through your whole body which work together and can actually change tension and shape through the myofibroblasts. This extends way further than only one muscle group, but through entire chains of fascia, muscle's and joints throught the whole body. In my experience as a physical therapist breath-release exercises speed up the process, because the myofibroblasts wil instantly change the line of pull if addressed correctly. This makes it possible to increase range of motion drastically in a matter of minutes without negative side effects! :D

    Hi! First time viewer. Nice video! I did however noticed some audio pops on a lot of the transitions between clips. Typically that's where you're mixing in audio clips without fading them in or out. 2-6 milliseconds will do, and it'd make for a even more pleasant video.
    Thanks

    I just stretched a tendon in the groin last night and it's so damn sore, 5 more days to go? I have a very high pain threshold, but i'm shuddering at the thought of this XD
