For the past year or so I've had AoM readers emailing and tweeting me about a book called Underground Strength. Finally had a chance to check it out and I had to have the author on. Zach Even-Esh is a strength and conditioning coach and author. His philosophy towards fitness really resonates with me: tire flipping, sledgehammers, squats, and deadlifts-- among other things. In today's show, I ask Zach about the Underground Strength Philosophy, why you should strive to be an athlete, and what a guy can start doing today to get stronger.
