Damn Back

About a month ago my left QL got a bit fucked and got sore/tight when I did heavy squats or deadlift variatons. It’s been slowly getting better. Today I decided to do somewhat heavy narrow-stance back squats, 4 reps of 295. Last week I did 5 sets of 2 reps of that weight just fine. Today the first set was good. I hardly felt anything in my QL. Then on my 2nd set as I was going down my back as a whole was not having it and I came up and did one measly rep and now even an hour later my whole back feels kind of fucked. Incidentally the QL feels roughly the same as always, but it’s more my lower back now. Bending over sucks and even breathing in a bunch of air makes me feel it.

WTF is going on?

How do I treat this in the short run?

And I’m guessing to stop doing back squats in this program. I already do front squats on another day. Would heavy, 3-5 rep per leg lunges work? (I can’t do too many reps of anything cause I’m cutting so not enough muscle glycogen)

Thanks

Nothing wrong with lunges. Stay out of pain though. Holding heavy DBs can be rough on the QL, and weight on the back can piss off the low back. Perhaps try a BB front reverse lunge.

BB front squat reverse lunge sounds like a good idea. I’ll go with that for a while

How long should it take for this bout to be over?

I can definitely be lazy about my mobility work sometimes, admittedly. I’ll give that a go. thanks
