I know that teeter definitely suggests to not invert with high blood pressure. You could try zero gravity or a really gentle setting and have someone check your pressure while you are on the table. It naturally raises blood pressure and everything rushes to your head. So if you already are high talk to your doctor. I decided to just throw mine away – I am sitting on the couch literally right now day 2 post op of bilateral hernia surgery from the thing. Not saying inversion is bad but unfortunately some of us just can’t invert.
