For starters, check out the hip slide thread: http://thesandtrap.com/t/29616/the-biggest-secret-slide-your-hips
Over-rotation is a major cause of lumbar injury. When you combine bad posture, weak core, over-rotation, and overswinging, it's no wonder such a large percentage of amateurs struggle with back pain. Your lumbar region isn't designed to rotate a whole lot. A max of 6% of your body rotation comes from that area in the golf swing. The majority is internal/external rotation of the hips and thoracic rotation. Your body is designed to keep some parts stable while other parts move. This shouldn't come as a surprise to you. Unless, of course, you ever tried to push a car while standing on ice and expected anything but falling on your ass. Because this is the function of the lumbar/core in sports (isometric stability, not explosive power), your workout should be tailored to that. I highly recommend against explosive, plyometric style lower back work like aggressively paced good-mornings, etc. Instead, the best research shows a correlation between high levels of isometric endurance and low frequency of injury. Ever wonder why so few tour pros complain of lower back pain even though they swing the club 112mph? A huge part is mechanics, but an often overlooked part is that they spend so much time bent over putting. Putting is pretty much nothing but isometric lower back endurance. This is the ideal exercise for developing lumbar stability, and it just so happens it's a great way to lower your scores. If you are going to put this knowledge to use, do some research on golf posture, specifically S-posture and C-posture faults. You want to learn how to keep your core "relaxed yet engaged". Far too few people know how to do that. Every good golfer knows exactly what I mean when I say that. If you can train that as you go about your daily routine, it doesn't take much time. The core recovers really quickly.
