Chris Finn is the Founder and CEO of Par4Success. He is a Licensed Physical Therapist, Certified Strength and Conditioning Specialist, TPI Certified Medical Professional, Certified Precision Nutrition Coach and a Golf Digest Top 50 Golf Fitness Professional. He and his team work with golfers of all abilities and ages to swing faster, play better and hurt less. Chris joins #OntheMark to tell his story and help you understand, from a physical point of view, why your golf-swing and your shots are doing what they are. He dives into 4 areas of the body, the Rotary Centers - the Neck, Shoulders, Thoracic Spine, and Knees - and illustrates how deficiencies in those areas can result in malfunctioning golf-swings. He shares research, he and his team have done, on GRF (Ground Reaction Forces) as they relate to Clubhead Speed and advises on which gym exercises promote speed and which exercises do not.  Regarding further speed improvement work, he talks about Overspeed Training, as well as contrasting Triphasic Training vs Traditional Training and he shows best practices for gaining speed and more power off the tee. This podcast is a must-download if you wish to improve physical well-being, golf fitness and strength.  Note, Par4Success have also provided a free physical assessment for you at par4success.com/mark.
