This is a follow-up report about "hanging by iron bar".

Frankly speaking, keeping hanging on a iron bar is pretty hard.

I know that moving my body front and back or side to side is low load for long time hanging.

However, if you try, you should do it little by little not to hurt your body.

Recently, I go to sauna once a week, and stretch in the sauna room.

I often had my abdominal and back muscles cramp

Though I stretched in the sauna today, I didn't feel such pains.

-----

Researching about it a little, Hanging Health Method make us effect to strengthen abdominal and back muscles and core.

Twisting on air seems to be a good stretch for me.

Anyway, if it prevent strained back, I am happy.

Because I have to keep sitting on my chair for 10-14 hours a day now.
