The Happy Gilmore is one of the first starting points to understand how the right leg absorbs pressure on the downswing. Watch this video of Sergio Garcia as he recently went full "Happy".
There is a difference between static pressure and dynamic pressure. This understanding will help the golfer gain control of their weight shift and know that being left or forward doesn’t always suggest trying to head in that direction.
When pressure hits you during a round then it's obvious that certain areas of the body begin to tighten up and the swing doesn't flow as easily. Learn what I did with Brendon Todd to eliminate this unwelcome tension.
How do good golfers produce stability in their lower half yet at the same time create lateral movement in their legs that support and drive through impact towards the target? - it's all about the ground pressure
Knowing how to use pressure in the legs and into the ground for longer can help eliminate the need to straighten the right arm into impact- and give you much greater control and ultimately more power.
