Episode 215 – Greg Potter, PhD: How To Improve Your Sleep

On this episode of RNT Fitness Radio, we’re joined by Greg Potter, who comes on to dissect everything you need to know about optimising, improving and understanding sleep. Greg helps a range of individuals improve their health and performance, from elite athletes to CEOs. Since he did his PhD on sleep, circadian rhythms, nutrition, and metabolism, Greg spends much of his time helping individuals sleep and eat better. Greg is also co-founder and Chief Science Officer of Resilient Nutrition, a nutrition and supplement company that makes performing better simple and delicious. Highlights of Greg’s career include coaching a sprinter to four gold medals at the European Championships; having his research featured in dozens of international news outlets, including the BBC, Reuters, and The Washington Post; working with the US Naval Special Warfare Command; helping to prepare two men to break the Atlantic rowing World Record; and being the sleep expert in a Channel 4 documentary on sleep and weight loss. If you’re interested in maximising all facets of your sleep, or just want to geek out on the science behind it all, this is one you won’t want to miss.

“It’s important to go to bed only when you are sleepy.”

Greg Potter
