Todd Hargrove is a great fitness and health writer at bettermovement.org. I've been talking with Todd for years and find his information and thought process excellent. He has a new book out which I recommend to everyone. I agree with much of it and the great thing with Todd is that we disagree on a lot too. However, Todd is open to your disagreements and discussions about contentious issue.
You can Todd's book at Amazon.
By the way, I get no kickbacks for this.
