Won't give this 5 stars, as it is let down by the 2nd person narrative, which fills out the book a little. However the advice is excellent. Eric's hypothesis is that foot strength and fore-foot running are key to running free of injury. I buy into this, having bought some minimal drop shoes and noticed how effortless running is in these compared to my heavily cushioned, heel strikers. However even though I ran a marathon recently, I can't run more than a mile in my minimal drop and this is where Eric's advice comes in. The exercises Eric advocates are easy to follow (once you get the slant, wobble board, swiss ball and walking poles!) and are clearly explained. The nutrition advice is fantastic. I have lost 5 pounds, just by completely cutting out sugar in my diet as per Eric's guidance. The advice Eric gives on the mental side of the training is good but he is not as strong on this as he is with the physical exercises. Definitely recommended though
Update on 2nd Jan. I originally gave this 4 stars but I have increased this to 5. After a month of following Eric's exercises, I have increased my pace from running 11:30 minute miles to under 10 minute miles and holding this pace consistently over 8 miles. Running feels effortless and I am only at first base with the exercises having not yet progressed to the wobble board. At this rate I'll comfortably be able to drop my half marathon time from 2 hrs 40 to under 2 hours by my next half in March. Unbelievable!!
