Mine is C5-C6 so the downforce of swinging can be tough if I don't stretch, lift and exercise. I wouldn't know about lower back, but with hitting, I had less lower body rotation.
I think it also depends on your swinging pattern. I had back problems at 15 years old due to the craze of fixing the right knee, having very minimal hip turn and a large shoulder turn and then spinning the hips very fast on the downswing. Very hard on the back.
Now i let the right leg straighten, the right hip turn out the way and allow the left knee and foot to be naturally pulled across. I combine this with a free armswing and i still have power but i'm not putting nearly as much strain on my body.
K,
thats what I was thinking too. Been using VJ Trolio's rendition of Hogan's pivot and its very rotational.(after the slide) Cant do it right now becasue of the back.
The True Golf Motion 3-D swing pattern I developed uses both hitting and swinging components. The pivot is rotational motion with little axis tilt. Weight is centered on the back swing and moves slightly left on the down swing. The back swing hand position is the top. The True Golf Motion 3-D Swing Pattern takes advantage of both pivot rotational and right arm thrust power and does not put stress on the back or shoulder joints. It is a breath of fresh air for golfers with back and shoulder problems.
is this the 'hammer" motion on your site? No rt arm extensor action from what I recall. Heard some people getting it out there w/ the pattern. What PA's are you using, 4 barrel?
