My friend and handstand teacher Nicolo Kehrwald has released a book on handstands! Everything you wanted to know in order to do them! It is an incredible little book.
Tara and I wandered into his living room for private handstand practices seven or eight years ago --- our first 2-hour handstand session was mindblowing.
I highly recommend that you pick up a copy --- Nicolo is able to talk about handbalancing as an art form and as a practice.
Get it on Createspace or Amazon.
