“I love what Mayne has done in this book. Whenever I read a “how to” boxing manual, I usually roll my eyes and confirm to myself that people don’t understand the DETAIL that goes into executing a punch. Mayne has done an amazing-detailed job of explaining how to execute the punch down to the wrist rotation. The best in the biz can read this book and reconfirm what they may know! This book is a necessity!”
