I screwed my back around a month or so ago doing deadlifts with 430 lbs.
I usually try to get 8-10 reps, but felt tired and rounded my back on the second rep.
BIG MISTAKE
No popping sounds or tearing feeling, but something just felt wrong and I terminated my deadlift session.
For the next couple of weeks I had very minor aches in my lower back; nothing major.
I left out deadlifts on my back day but still did squats on leg day, just a bit lighter.
Last week, the day after squats my back started getting major pain and I still have it today, one week later.
I'm doing legs again in 20 min, but I'm only going to do very light squats for very high reps.
