As a sports scientist and nutrition expert, Kerstin Hardt combines over 25 years of practical experience with a unique, holistic approach, making her one of the most sought-after experts in health, mental training, and performance in the German-speaking world.

Her approach is based on the „Five-Pillar Principle" she developed, which synergistically combines nutrition, exercise, mental training, stress management, and intuition. Her core focus: How people and companies can permanently break free from the stress cycle through the interplay of physiology, biochemistry, and mental training, thereby achieving peak performance without exhaustion. Kerstin Hardt is convinced: „We are not weak; we are simply dependent on old patterns." Breaking free from these dependencies and unleashing the full potential of human physiology and psychology is at the heart of her work.

Known for her appearances on media outlets such as ZDF and SAT.1, as well as for her regular contributions as an expert to FOCUS Online and the Handelsblatt, she explains complex concepts in neuroplasticity and biochemistry in a tangible, motivating way. As a keynote speaker, she inspires audiences on major stages and at DAX-listed companies, while her podcast „Gesundheit kannst du lernen – Mehr Lebenskraft mit Kerstin Hardt" reaches thousands of listeners every week.

Her expertise is not only grounded in theory but has also been proven in practice through her work in elite sports (including with Eintracht Frankfurt) and her coaching of numerous CEOs and executives. Through events like „ENERGIZE YOUR LIFE," she creates spaces for transformation where modern tools such as HRV (heart rate variability) measurement and in-depth mental training are used to transform stress into sustainable vitality.
