Can exercise be one of the most powerful anti-cancer therapies available today? with Robert Newton

In this compelling episode of the Dr. Geo Prostate Podcast, Dr. Geo sits down with internationally renowned exercise oncology pioneer Professor Robert Newton to explore the groundbreaking science behind exercise as medicine for cancer.

Inspired by his father's battle with prostate cancer, Professor Newton has spent decades researching how targeted exercise can improve treatment outcomes, preserve muscle mass, strengthen immune function, reduce treatment side effects, and potentially slow cancer progression. Together, Dr. Geo and Professor Newton discuss why muscle is far more than a movement organ—it functions as a powerful endocrine organ that releases cancer-fighting compounds known as myokines.

The conversation dives deep into exercise intensity, resistance training, chemotherapy and radiation timing, wearable technology, exercise "dosing," and the landmark Phase III clinical trial that demonstrated exercise can significantly improve survival outcomes in cancer patients. They also discuss practical strategies for overcoming fear of the gym, maintaining muscle during androgen deprivation therapy (ADT), and why sitting all day may undermine your health even if you exercise regularly.

Whether you're living with prostate cancer, supporting a loved one, or simply interested in maximizing your healthspan, this episode provides actionable, science-backed strategies to help you move from surviving to thriving
