Description
Why does sports science so often ignore the athlete’s most revealing health marker? This book breaks the taboo by exploring the inseparable link between physical performance and sexual vitality. Through a holistic approach, you will discover how key hormones such as testosterone and cortisol regulate not only your muscles, but also your desire and your deep energy.
This guide offers a precise dive into the vascular and nervous mechanisms that govern performance. You will find practical protocols on critical micronutrients (zinc, magnesium, vitamin D), nutritional timing before and after training, and the often-overlooked dangers of restrictive diets such as cutting phases or fasting. Don’t settle for being only a strong athlete—become a physiologically complete athlete
