[O.B.Left]

That was a very good clarification of the role of the right shoulder OB Left.

However, the pivot is the Black Jack of power generation. Work done by the most significant joints in the body during a golf stroke:

1) Lumbar
2) Right hip
3) Thoracic
4) Left hip and right elbow.
6) ........

I've added the numbers:

74% Zone 1
20% Zone 2 (11% elbows, 9% shoulders)
6% Zone 3 (Wrists)

This are the average figures across 4 golfers on different skills level. Their power profiles varies very little.


As a curiosity, the table also shows that the left ancle and left knee does negative work. You have the cause of Tigers previous knee injury right there in black and white. So if you flare your front foot more open at address, the Zone 1 percentage is likely to increase.

Interesting stuff, Ill give it a read tonight, thanks.

I played with a 75 year old guy last week. He could barely walk, I had to help him in and out of bunkers for instance. As close to zero pivot as you could probably get.......but what a set of hands on the guy. He'd been playing for 60 years and you could tell. He could still hit it 200 off the tee.

Standing on one leg I can hit it pretty good. Some guys can hit it 250 off their knees.

If you took the arms totally out of the swing by lashing a club to your body in some manner.........how far could you hit it? I dont think very far. In essence, its a comparison of the speed of the Right Shoulder vs the Hands isnt it? You can get a little right shoulder into the ball even off your knees it should be noted.

Dont get me wrong, I think the Pivot is very important and adds tremendously to Power for sure but the Arms are the primary source of Power. Ill give it a read though ......I'm here to learn and improve thats all....which means making mistakes. Lots of em.
