The positives about this book are...well essentially that it was greatly needed! I like the explanation and I could immedistely pinpoint problems in my running form.
However I'm not giving it a full 5 stars because the strength training part does show some ignorance in the field. First off this book is set exclusively for runners and as runners I mean people who only run, without doing any other sport. As a bodybuilder meaning to correct my running I see that advising people to not train certain muscles is a nonsense, learn to use the right muscles instead but NOT training something is a bad idea. As for the "bodybuilders don't do cardio", that's a piece of broscience that could be left out, bodybuilders do cardio, plenty of it...just you probably don't see them running on the track because weight is usually considered a problem when bounching in and out of your joints. I guess he needs to take a step back and look into the whole picture, there is not in the body a muscle that does not need being trained. The Rectus femuri is going to impair the hamstring? Then work the hamstring more/better, there is no reason to not work the rectus femus, since it's going to take in plenty of shock and bouncing from running. Nonsense.
