Ouch...hate when that happens and it takes about a week or so for the pain to go away. Not trying to sound like an ass but seems you been punishing yourself and the hurts keep coming so maybe a time to back off heavy stuff for a bit?205lbs
SSB squat 335x3, 350x3, 350x3, 350x9
SSB good morning 155lbs for 3x8
Dumbbell step ups 70's for 3x5 each leg
Did half my accessories and called it a day. Tweaked my left knee on step ups. Gonna drop these. Single leg stuff sounded good in theory. Still feeling discomfort in my lower back too. Might just do like two weeks of strictly belt squats for lower body and give my lower back a break. I don't know yet.
