Based on cutting-edge research and extensive practice, this book reveals the important role that muscles play in human health and the key role that strength training plays in enhancing muscle mass. The positive fitness methods recommended in the book help readers to fully listen to their body's signals during strength training and reach a state of muscle exhaustion, thus gaining a range of physical and mental benefits in a fraction of the time. We hope that more people will be able to keep their bodies energized and live healthy, happy lives through "anti-aging strength" and positive thinking fitness methods!
