If your body manifests one or several of the following eight symptoms, then you are suffering from Jin-Suo (tendon contraction):

[Test 1] Ability to squat

Do you find it increasingly difficult? One way to tell is to try using a squat toilet.       

[Test 2] Can you lift your legs with ease?

Remember climbing stairs in strides? Do you find it increasingly difficult?

[Test 3] Can you bend from the waist easily?

Each time, bending becomes increasingly difficult and you might easily end up with twists and sprains.

[Test 4] Can you walk or run in long strides?

If you can only take small steps, then it’s time to take note.

[Test 5] Is your one leg longer or shorter than the other?

“How come I never realized it?”      

[Test 6] Can you stretch and bend the arms?

Try holding the rings on a bus or train.

[Test 7] Can you stretch your legs in a seated posture?

“Why can’t I stretch out as wide as others?”

[Test 8] Can you turn your body easily?

“Ah, it is not because I am fat, but because I’ve got Jin-Suo?”
