Cardiovascular diseases are the leading cause of death in Germany. Doctors preach prevention, healthy living, and exercise. But who really enjoys hearing cautionary words? An unhealthy lifestyle and excessive stress can lead to the worst outcome: a heart attack! Now is the time to make a change. To enhance everyday performance, self-confidence, and quality of life, the heart needs to be trained and challenged again. The good news is that with the right guidance and motivation, life can quickly become enjoyable again—and even more valuable than before. The authors know exactly what they are talking about: Michael Andressen himself suffered a heart attack and describes his recovery, which he successfully managed with the help of Florian Münch, who developed the corresponding training plan. This work is not a dry scientific treatise.
