By Mina Sakita "Relieve Your Fatigue at Work, Home, School, with Awesome Stretches."
This is a very interesting book to find in here. Working with computers all day, I was looking for something like this. You don't need to read Japanese to understand follow the illustrations and just don't over stretch, take it easy.
I'm trying some of these exercises, very easy to do and it feels good.
