That's reassuring and interesting, about the "couple of hours". I know that after aerobic exercise bp should return to normal within a few minutes. And mine does. Except anaerobic exercise causes it to hang around at a higher number for an hour or two.
Powerlifters can go up to something like 370/300 during lifting, according to Dr. Elefteriades of Yale University School of Medicine.
I've always found it interesting that powerlifters typically don't have a higher incidence of strokes. I once read that the intense exercise causes a certain hormone to be released, which protects the cardiovascular system. Can't remember what that was but I know I saved the article on my hard drive somewhere.
After stopping TRT cold turkey a few years ago I developed high bp and I was walking around with 210/110 (not during lifting) and didn't know it. That got taken care of (back to 110/65) but now I'm on a beta blocker, which really sucks.
