I used to lift a few years ago, before I was a passenger in a serious car accident. Now, half my spine is fused together with titantium. My lower lumbar L4 and L5 shattered, and are now fused with the two above it and two below. I broke one of the rods a year later while I was shoveling snow, and had to get it replaced. It's pretty sturdy now with more metal fusing it together, but I don't know if I should start lifting again, at all. Anyone have experience with something like this, or know someone who has?
