Last Saturday, I finished Dan John's 40-Workout Strength Challenge. Yes, I've written about "challenges" before (noting that they are often inappropriate, to put it nicely). But this one is more like a "program" than a "challenge."
It's based on concepts from the book Easy Strength by Dan John and Pavel Tsatsouline, an excellent book with a wide range of great information but more suited to trainers then people just looking to get fitter or stronger. My experience with it follows.
