Have been a long time fan of Richard's "MedFitness minute" quick videos that make salient points about health and exercise. And am impressed at his diligence of never missing a day! (as far as I know)
Richard has a degree in nutrition and is a long time proponent of rational exercise. He is very knowledgeable and does a great job with his clients. For anyone near St. Charles, Illinois, you can get a free introductory session!
