The first is Matt Perryman’s Squat Every Day. I titled this post “lifting ebooks”, but SED is of vastly broader interest — it’s a look at the human stress response, acute and chronic, psych- and physiological, through the lens of high volume resistance training (“Bulgarian style”, if you like). It’s really, really good, and it’s seven bucks. If you have any interest whatsoever in my training and nutrition posts, you really ought to pick this up.
The second is Jim Wendler’s Beyond 5/3/1. It’s more or less exactly what it says on the tin — an occasionally-disorganized cornucopia of ideas for taking your training beyond the standard 5/3/1 format. If you’re not familiar with 5/3/1, get one of his other ebooks first. At twenty-five bucks, it’s not the no-brainer Squat Every Day is, but it’s stuffed full of good content, worth reading and re-reading like Wendler’s other books.
