Weight Lifting Is a Waste of Time: So Is Cardio, and There's a Better Way to Have the Body You Want

Very good. You must consider investing on X3 after reading this book. It Is worth every penny. There Is a better way yo workout!!!

Excellent condition

Sehr interessant. Wenn dieses hocheffiziente Training mit wenig Verletzungsgefahr funktioniert würde dies phantastisch sein. Ich werde es testen und bin motiviert und gespannt. Allerdings ist die Hardware auch bei Amazon viel günstiger und besser. Sportboard und bar. Othersports cool auf Amazon.

I want to be completely transparent, before starting this review. I am an X3 user, and have been for about 4 months prior to reading this book. Im also well aware of confirmation bias and a whole bunch of other subconscious cognitive biases that humans have, which definitely includes myself. Also, I’m not paid by X3, and have no affiliation with the product, manufacturers or its creators. I bought the product with my own money and have not been paid for any testimonials whatsoever. That is my preface to this review.With that being said I went into this book, thinking it was going to be more of a subjective opinion about the product itself. Having used X3 for going on 4 plus months now, I subjectively can confirm that the product works. However, I thought this book was going to be heavy on trying to up sell the products produced by the manufacturer and shorter on the science behind its claims. Although there is a little bit of that sprinkled here and there, it’s not as blatant as other books that are trying to sell you something.The research that went into this book is pretty astonishing. Every study is cited at the end of every chapter and the theory’s presented make sense. I even double checked multiple cited studies to confirm, and confirm I did. Even some of the most outlandish claims, such as “cardio is pretty much useless,” the book does a good job explaining its claim and citing some pretty fascinating studies. The author even goes a step further to address the criticisms of his own claims about “cherry picking,” certain studies. Which I found really refreshing. Just the fact that an author is aware enough of their own biases, and tries to work through them in a coherent and scientific manner was super fascinating to read.With all that said I will say, that I found one aspect about the science a little perturbing. It’s more of an omission, but still a little annoying. The book does not mention a single time the role that fiber plays (or doesn’t) in the whole general theory on nutrition presented. This is a bit annoying, considering its claims about nutrition and strictly its encouragement of a strictly animal protein diet. It goes over extensively the many fallacy’s of carbohydrate rich diets and the harm that they can do, which is becoming more and more obvious in the current time, yet it doesn’t mention 1 time the role of fiber, which is a carbohydrate. And as of this writing I have yet to find a study touting the harms of fiber. I just wish the authors spent a little more time delving into that issue.All in all though, I thought it was a really intelligent thesis on the science behind variable resistance training. But don’t take my word for it, please do your own research. Read the studies! Even the ones that go against what your intuitive thoughts are. It will only make you a smarter more educated person and as far as I can tell, can only lead to a better understanding of exercise.

El libro está muy bien ya que explica su método, las conclusiones a las que a llegado y su producto inventado. El problema desde mi punto de vista es que se auto-promociona en muchas paginas. También hay que decir que el producto comercializado es extremadamente caro. El trabajo científico y los ejemplos puestos merecen la pena ser probados. Aún así recomiendo este libro saltándote toda la paja.
