The BiG Scuba Duo, Gemma and Ian chat to Rob Colley. Rob Colley is a former Royal Marine and Specialist Military Unit (SMU) operator with over 23 years of elite experience leading and performing in some of the world’s most extreme environments on land and under the sea. Awarded the Distinguished Service Cross for Gallantry, Rob spent much of his military career operating in high-pressure, high-stakes scenarios that demanded total focus, resilience, and leadership under stress. Following his transition from military service, Rob turned his attention to human performance and recovery, serving as Director of Elite Performance & Training at DEEP Research Labs developing protocols to prepare scientists and explorers for extended subsea missions. Today, Rob is the founder of Thrival Instinct and the creator of the Thrival Instinct Method for Inner Mastery a powerful system that blends breathwork, mindset training, and performance psychology. His approach helps military personnel, veterans, corporate leaders, and high performers break free from survival mode and reconnect with clarity, resilience, and purpose. Through retreats, coaching, and digital programs, Rob now helps others build inner strength and live with intention—especially those who’ve faced extreme environments of their own, whether physical, mental, or emotional.
