Back is inching toward recovery but no meaningful progress yet. Usually this kind of thing takes 4 or 5 days. Today, I started out by testing the waters and squatting the bar, then thought it best to move on to the car deadlift simulating lift. Worked up to 5 plates on each bar and did 15 reps for two sets of that, after doing 8 with 4, 3, 2, and 1 plate(s). I was able to get some heavy load on my legs at least without back problems, though I had to cinch my belt pretty damn low on my hips to protect my back, which made it tighter than usual.
Tomorrow I'll probably bench again, and then hopefully can resume a normal week on Sunday.
