I'm a big fan of lifting heavy things. But I also have to admit that much of my lower back pain has been caused by injuries from lifting heavy things. All sports are going to eventually cause some form of injury, and lower back injuries are common among people who lift heavy things.

For the foreseeable future, I've decided to avoid low-bar squats because they use my lower back too much. I've switched to high-bar, which allows me to keep my hip and spine stacked in much the way talked about in the article. I've also made a point to lower the lifting intensity when I increase the intensity of my other activities (grappling). Pushing hard with heavy weights and then making hard demands in other activities can cause problems as well.
