Tony Robbins explains how he sustains a massive amount of energy with no stimulants and little sleep

Tony Robbins is 55 years old, but if you see him on stage or even have a casual conversation with him, you'll see he has more energy than most 20-somethings.

Robbins is not only the personal performance coach of business leaders like Salesforce CEO Marc Benioff and hedge fund manager Paul Tudor Jones, he's the head of a conglomerate of companies and the main attraction for long, incredibly lively seminars that he has relentlessly given around the world for the past 30 years.

He told Business Insider that he wasn't born a naturally energetic person, that he gets very little sleep when he's on tour, and that he doesn't take stimulants for a boost.

Instead, he's developed strict habits around diet, exercise, stress management, and the approach to his work. We'll explain below how one of the world's greatest distance runners, an 85-year-old Catholic nun triathlete, cryotherapy, and a strange anxiety-reducing headset have contributed to Robbin's seemingly limitless energy.
