An excellent resource. I've been trying to understand why as a petite woman I've got cartilage damage and how I can prevent any further damage. I've bought running technique DVDs four times the price of this book only to find they explain what it is with very little information about how to get there. I've paid way too much for a gym membership where they supposedly provide specific training for running technique only to find the trainer is LAZY. After bringing on old injury back in full force by prescribing plyometrics with no instruction I was told there is nothing that can be done for running technique without plyometircs. This book with it's strength training and preparation phases has been my saviour and given me new hope. The cheapest and BEST resource I've come across after years of frustration searching elsewhere. Thank You!
