Sci
It is lower body and setup that need to change. You dont use the ground at all and the hands are too early into impact with a massive flip.
As i said in the video, go and get copies of your favourite golfers and copy their leg action... your upper body turns well, just in the wrong direction as your lower half is just way too active. Your legs have to store and release the power from your upper body and the angles you create with the clubs and arms. You would hit the ball flatter and further with a better leg action... at present you are pretty much jst hitting a lob shot with everything
