Well, I consider myself fairly tough. I've never broken anything. I've never hurt my lower back before even though it's a common injury. I'm pretty flexible, like possibly too flexible. I might have hyperextended my back during the squat when I lost balance and tried to recover by thrusting my hips back (I was falling forward and then I started falling sideways but I recovered) or it might have been on the deadlift when I actually felt the pain sharply.
It seems to me that a person ought to build strength in the lower back so these things won't happen.
I'll look for that sodium ascorbate stuff. My skin is probably too far gone from age, fair skin and So Cal sun (with my refusal to use sunscreen.) My parrot pulled off one of those pre-cancerous lesions on my face last night, bless her little heart. She knew it didn't belong there.
Female, 5'3", 50, Starting weight: 163lbs. Current weight: 135 (more or less).
