I mentioned this in another post here recently, but I also had a back injury from some fucked up form for a single rep. Got the MRI, looks like it's spinal stenosis. I ended up going to PT and, surprisingly, we found a way to keep the pain away pretty much all the time. I have to basically work my back out once every two days, but I basically do a back excercise every day now. That being said, idk how long this will work for but I'm just enjoying the pain free moments right now. Let me tell you, chronic back pain is fucking hell. It is important to warm up, and if anything gets sketchy to just put it down and walk away. It's just not worth it.

Alternatively, you could just keep weight relatively low. Although I did my injury at a low weight
