I'm self taught, and Have these books in my collection:
Reflexology: A Basic Guide - Crane
The Massage Book - Downing
Massage Basics - Sechi
Whole Body Massage - Lacroix, et al
I started with muscle massage in high school as a sports trainer - got my practice there, and now just do it for friends.
My #1 tip would be :Be Into the Massage. When I'm giving one ... I'm devoting all my attention to that person, and you learn to read body signals as you're working with the muscles. Find a willing participant (like THAT's hard!
) and then just start soft ... go from there. I know tecoyah doesn't mind my massages.
