The Hardness Factor by Dr. Steven Lamm is a comprehensive men’s health guide built around a bold premise: the quality of an erection is one of the best indicators of overall well-being. Combining medical expertise, nutritional strategies, and targeted exercise, Dr. Lamm offers practical, evidence-based programs to boost sexual performance, enhance vitality, and improve general health. This book features both quick-action plans, such as the “Four-Day Insurance Policy” for fast results, and a longer “Six-Week Hardness Factor Program” for lasting improvements in stamina, strength, and confidence. You’ll find guidance on diet, supplements, and fitness, plus recipes from chef Waldy Malouf designed to support sexual health. Whether you’re seeking to reignite desire, maintain lifelong performance, or simply adopt a healthier lifestyle, The Hardness Factor provides a clear, science-backed path forward.
