I am a physician and a trainer. I came from a middle distance running background. After medical school I continued to run but of course never got to the point where my fitness was at the level that it was when I was competing in college. I started adding strength training using mainly Olympic Weightlifting. While I was certainly gaining strength, it was not happening as fast as I would have liked. About 5 months ago I purchased Starting Strength. The book is very detailed, but unlike most books on training, it does not put you to sleep. It holds your interest through the plain language, and often funny, explanations of what should be done and also why it should be done.
