I would love to hear Greg's thoughts. I started this last week. It is significantly harder than I thought it would be. Yesterday I carried 180 lb's for a 100 m's and I was surprised at the difficulty. I also carried 80 lb's for .8 miles. I am doing it on non lift days.
What we think, or what we know, or what we believe, is in the end, of little consequence. The only thing of consequence is what we do. -John Ruskin
