Dr Harry: without medical training I could have died

If illness or injury is stopping you from training, have a listen to Dr Harry Weisinger. He is a great doctor for anyone dealing with recovery, partly because he writes scientific papers on nutrition and physiology, but also because he has fought back from terrible health problems of his own and is now in far better shape than he has any right to be. 

Dr Harry also provides expert advice to a supplement company called Truth Origins.
