One of the most fundamental components of athletic movement is learning how to connect with the ground! As a golfer ground force is crucial for rotary power and generating club head speed. Thought: The fastest athlete or the athlete that can jump the highest isn't the athlete that moves the fastest. It is the athlete that can exert the most force into the ground and control that force. In this video Brandon Harris CO Founder of Premier Fitness Systems a Scottsdale, Arizona based fitness studio specializing in golf performance and teaching athletes to increase their ground force production shows a few foundational exercises to learn how to create better ground forces for increased club head speed in golf. The key to understanding ground force and how it works is to first understand Newtons third law of motion. Third law: When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body. To create power in the golf swing a golfer must drive the legs forcefully into the ground. This results in the ground pushing back up into the golfers body with a equal magnitude of force. This force is know as the ground reaction force or ground force. The ground force is transferred up the kenetic chain from the ground to the legs into the pelvis up through the core and shoulder complex to the arms and finally the golf club and to the ball. If a golfer doesn’t have stability and strength in the legs, pelvis, core and shoulder complex there will be major loss of energy transfer and lack of club head speed.
