If your body manifests one or several of the following eight symptoms, then you are suffering from Jin-Suo (contraction of tendons):
Ability to squat – do you find it increasingly difficult? One way to tell is to try using a squat toilet.
Can you lift your legs with ease? Remember climbing stairs in strides? Do you find it increasingly difficult?
Can you bend from the waist effortlessly? Each time, bending becomes increasingly difficult for you and you might easily end up with twists and sprains.
Can you walk or run in long strides? If you can only take small steps, then it’s time to take note.
Is your one leg longer or shorter than the other?
“How come I never realised one of my legs is longer than the other?”
Can you stretch and bend your arms? Try holding the rings when you ride on a bus or train.
Can you stretch your legs in a seated position (assuming a horse stance)?
“Why can’t I stretch out as wide as others?”
Can you turn your body easily?
“Ah, it is not because I am fat, but because I’ve got Jin-Suo?”
