"I don't think there is another strength training resource available today that's as thorough or well-explained as the Principles of Strength Training. I have learned a lot of NEW information and it's great to have all these resources in a single ebook. That said, I thought it would share more on how to design programs using the principles outlined, and I was bummed to see it focus so heavily on powerlifting (considering there is another powerlifting-specific ebook already). Still, it's a fantastic resource that I am proud to own."
