Ryan Parsons is a peak performance expert, veteran MMA coach, manager, and consultant. He received his doctorate in chiropractic medicine from the Southern California University of Health Sciences, Los Angeles College of Chiropractic, after an underwhelming wrestling career. Parsons has worked with world champions in every major fight promotion and is the inventor of Radius Wraps, the first combat sport product to undergo a peer-reviewed university clinical trial. He has cut weight with elite athletes on five continents in all kinds of places—in saunas, steam rooms, hot tubs, hotel rooms, city parks, the beach, and even at an arena under a camera crew’s lights. He is the coauthor of The Four-Pack Revolution with Chael Sonnen. He lives in Los Angeles, CA.
