Hard is good, harder is better -- for your health, your libido, your life. Such is the provocative premise behind Dr. Steven Lamm's The Hardness Factor, a groundbreaking book that will change the way men live and love. The Hardness Factor measures male health through the quality of an erection -- perhaps the greatest male motivator for better living. Here for the first time are scientific, evidence-based regimens -- emphasizing nutrition, supplements, and exercise -- to increase erectile quality. After following The Hardness Factor, you will not only achieve optimal health and sexual fitness but also understand why the penis is the best barometer of a man's health.
