Danny Arnold

Danny Arnold is a consultant in the HHPI where he collaborates and lends his expertise in the development and implementation of sport science and testing protocols. For over 18 years he has been recognized as an industry leader in human performance offering the highest level of integrated and innovative sports training and sports medicine for anyone regardless of age, sport or skill level.  With a proven track record, he is the Founder and Director at Plex and has designed programs that have helped thousands of individuals, from Super Bowl Champions, Olympic Gold Medalists, to developmental athletes learning to play their first sport improve their performance and overall wellbeing. 

Arnold's pursuit of excellence and innovative approach to training has received much acclaim from local and national media. He doesn't settle for tradition - he challenges it. Arnold believes that you don't just do things because we've always done it that way.  One of his biggest contributions to athletic development is the belief that you do not always need to lift heavy weights to improve strength and power at your position. To Arnold, range of motion, reaction, balance, and exercise velocity play a larger role in functional power development. John McClain, Associated Press and Head of Sports Division at the Houston Chronicle said of Arnold, "I've never seen someone improve athletes in their craft, as much as I’ve seen Danny Arnold do.  He's the best in the business."
