Hi Ron! I would rcomend Pavel Tsatsoulines "Power to the people" book. You can get it from dragondoor.com I have had great sucsess alternating this approach with EF. The book will give you a basic understanding of periodization, and appropriate volumes of work which can be performed without overtraining. My money is on a combination of HEAVY weights, yoga, sprinting and as much random play as I can find. Hope this helps! Robert
