With the cost of all the private coaches, camps, and specialized training out there, I decided to take matters into my own hands.

No lo encontramos en ningun. Otro sitio. Un libro maravilloso

If you have followed any of Calz or Mike T's work, then this book is highly recommended. A word of warning, this book has complexity around it and it challenges the normal S&C Model (i am going thru it a 2nd time and learning more again), I have taken away a tremendous amount of knowledge from it and there has been over a dozen gold nuggets in this book that are worth the price of the book alone. Highly recommended.

Triphasic Training 2 is an absolute game-changer for anyone serious about athletic performance. Cal Dietz's depth and clarity in presenting these 14 new methods make it incredibly easy to apply, whether you're working with elite athletes or just looking to enhance general strength and stability. One of the biggest takeaways is how adaptable the system is—it’s not just about raw power but also about managing fatigue, refining movement efficiency, and making long-term sustainable gains. The strategic use of eccentric and isometric phases has made a noticeable difference, especially in stability and injury resilience, which is crucial for high-impact sports like judo. For coaches and athletes alike, this book delivers a structured, evidence-based approach that’s easy to integrate into any training plan. The included video links and programming guidance are a huge plus, making it even more practical. Whether you’re preparing for high-level competition or just looking to refine your physical preparation, this book is worth every penny.

I have been waiting for this book from the moment I heard it was being written and it didn’t disappoint! It is written so you don’t have to read vol 1. This is a must read for anyone in the athletic world or the average gym goer . Each chapter is well written out and easy to understand for everyone , Once you buy the book there are links of exercise and program design . Well worth the money ,

Book is awesome. There are methods you won’t find elsewhere. I am amateur athlete, not a coach but it’s still worth it. Triphasic I is also great. Get both.
