quote: Coil is necessary to store the angular difference between the upper body turning 90 degrees and the lower body turning 45 degrees(or less). Having a stable lower body while turning the upper body creates power, ie. Newton's law: for every action there is an equal and opposite reaction. Or in golf terms, energy transfers from stored(top of backswing when upper body is coiled)energy to kinetic energy(turning back into the ball) by the final whip through the end of the club into the ball.
Nope....
Coil is nothing to do with creating power and is just a myth. Physics and the understanding you have towards the golf swing is all completely incorrect... and dropping newtons name doesn't make the attempt anymore complete.
Your body is not coiling as though it was a spring despite what those idiot moron instructors believe (that haven't thought about the swing in their lives, can't play themselves, its just something to preach that sounds good to people that don't know any better.... very often in golf teaching... the better the bull...the better they get paid... with very few exceptions).
The solution is simple for all to understand - get a piece of card or a book and tilt it forward 45 degrees to approximate your back - now to give you understanding im going to show you two things to do
First with the bottom edge level - you will see that if you rotate the bottom edge 45 degrees that the top isn't quite fully turned...
Now second time put a tilt in the trail side and then rotate it again - evola we have 45 degree turn bottom edge and 90 turn bottom edge - optical illusion....
Congrats the book just did the golf turn without coiling like a spring - must be magic !
