The test is called the “Beighton Hypermobility Score” or the “Beighton Score”.
It consists of 5 parts and is scored out of 9.
If you score between 4-6 you are considered to have lax joints, and if you score more than 6 you are considered hypermobile.
Watch the video below to see the 5 parts, try it out, and let me know in the comments what you score. I was a 0/9 (almost a 1/9 )
Also, if you know someone that is really flexible. Share it with them to see how they do.
