Read it again! Watch his clips. It will change your life for the better. Get out there and just move.
Don't get me wrong, he's a beast, but I'm not running marathons, triathlons, becoming a Navy Seal, passing Army Ranger school etc. Dude ran some races with a broken leg, and shin splints.
It's OK , David. We know you are an alpha dog. Now stop taking years off of your life. He had to have heart surgery too.
He spent the majority of his life pushing it to the limit. Nothing wrong with jogging a mile instead of 20+, and then do a heavy lifting session after.
Many of the other SEALS didn't like him , because he made them look bad.
