Ruck Up or Shut Up is THE comprehensive guide to Special Forces Assessment and Selection, the gateway barrier to entry to the US Army Special Forces...the storied Green Berets. This book is more than just a manual to get selected, this book is a prescriptive account of SFAS and a descriptive account of the culture, legend, and lore that surround SFAS.

Not everyone who reads this book will go to SFAS. There is still much to learn within these pages. There are great stories and lessons to be learned for just about anyone. For those who are already in the pipeline for Selection, these pages are a manual for what you can expect at Camp Mackall. For those on the path but not yet committed, you will likely find words of motivation and confirmation that will help you to commit. For those that are searching for something more, know that you have found it.

This is the ultimate program for Special Forces Assessment and Selection prep. Along with Ruck Up Or Shut Up, this guide provides everything needed to face the harshest assessment environment imaginable. SFAS is the ancestral proving grounds of the legendary Green Berets, and it requires aspiring operators to perform at the absolute edges of human performance. Preparation is the key to performance.

Shut Up and Ruck gives candidates inside access to top performance coaches in every assessed domain. Everything from the exercise science behind the big six lifts to the evidence based literature for the best way to build rucking performance. We cover the physiological realities of Zone 2 cardio and speed workouts.
