Standing in spin class, stair mill or stair master, squats, leg
press, etc. seem to be where I have to watch myself. Also, I am careful not to hold my breath during exercise, and I avoid isometric exercises (Valsalva maneuver). Lots of people have strokes on the toilet because they are doing the Valsalva maneuver. Another thing I have noticed is how much harder it is to raise my bp now that I am lifting again.
