Sorry but this is in the wrong place
I am confused by the use of the phrase of "Don't have your arms ABOVE your head with high blood pressure". I understand this when you are sitting or standing. It obviously refers to your arms being raised to the ceiling. But if you are laying on your back, does having your arms ABOVE your head mean that they are now pointed at the wall, or are they still pointed to the ceiling? I am a personal trainer and have been told this rule. But it would seem to me that laying on your back with your arms pointed to the ceiling and carrying a heavy load (barbell with weights) is at least as bad as sitting and raising a weight to the ceiling. I have been told that laying down is perfectly fine, but the inverted bench press, where your head is lower than your feet is not. It would seem to me that it is merely about gravity and the level of your heart. ANY body part that is higher in elevation than the heart causes problems for blood pressure is my understanding.
The basic reworded question is: Does laying on your back with your arms raised to the ceiling elevate blood pressure?
