I just sat down at the computer, Googled a few LINKS, and here’s what I found out, condensed into my own words:
We hear a lot about hip rotation in the golf swing. Unfortunately, hip rotation is a result, not a cause, if we look at the swings of expert golfers.
Many golf instructors teach hip-turn. Hip-turn can be a valid “Feel” thought…as long as the player realizes that Feel Is Not Real. If a golfer feels or sees hip movement, and attempts to teach others this “Feel” thought, there is the danger that someone might take it LITERALLY and actually try to turn their hips with their hips. And, if hip movement is exaggerated, it can result in lower back pain. Uh-oh.
In the past, we could excuse golf instructors for parroting the same old nonsense, but now, with computers and Google, it is easy to learn the function of the hips. In golf, they don’t turn—they GET TURNED. (That is, if you want a pro-style swing, and are physically capable of it.).
The function of the hips is to provide range of motion, flexibility, locomotion, and to maintain balance. If we try to turn our hips…with our hips…then what is going to provide our balance? The results would be weak out-of-sync rotation, loss of balance, and possible injury. Not good.
What kind of movement can we expect from our hip muscles? Forward and backward movement of the legs, moving the legs to the side and returning them, and inward or outward rotation of the legs.
We do find that smaller muscles going from the pelvis to the hip help to rotate the hip. This is the only hip rotation caused by hips–but we’re not looking for this because we want to use more powerful muscles to provide rotation.
If we want to find out what turns the hips, we’ll have to look somewhere besides the hips.
“Hips,” as a result, might work. As a cause…I doubt it.
