Author of his new book "Power and Pinstripes" Jeff Mangold joined The Rob Dibble Show to discuss his book about his years as the strength and conditioning coach for the New York Yankees. Jeff talks about some of his experiences with the team and starting in the 80's working for managers like Yogi Berra and Billy Martin, to working with some of the most recent Yankee legends. Jeff also talks about why strength and conditioning sometimes gets a bad rep and which managers didn't want anything to do with it.
