In this episode, I’m joined by Dr. Nicky Keay — medical doctor and specialist in exercise endocrinology — to explore how hormones shape health, training adaptation and athletic performance. We dive into key topics including RED-S, energy availability, menstrual health, female athlete physiology, and the unique challenges faced by master athletes.

Dr. Keay explains how hormonal imbalance develops, why it’s often overlooked in sport, and what athletes, coaches and practitioners can do to protect long-term health and optimise performance. We also discuss her book “Hormones, Health & Human Potential” and the practical frameworks she uses to help athletes thrive.

If you want to understand how hormones influence training, recovery, resilience and performance, this episode is a must-listen.
