Thank you most kindly Dave, I appreciate this. Isn’t it interesting how eloquent our bodies are? Yet so many of us either don’t listen or don’t want to listen- at considerable cost. My BF’s a software engineer so he can relate- but he’s also a bodybuilder. In these times when the computer/device/TV form the center of our existence, it’s a real challenge to create a program that undoes the damage of too much sitting. Bravo to you.
