Yup, Hypertensive at least since college (if not high school), too! Hooray us 
, lol
As part of prep for my first bodybuilding competition, I’m tracking my changes in blood pressure (2x/day) and blood work (every ~45 days) as I go. I really want to see if everything involved with shredding is going to improve anything (posting and tracking all that here).
I am very interested to hear what you try and the results (or lack thereof). Please keep us posted!
I highly recommend getting periodic blood work. You can pay out of pocket without a doctor if you use a site like WalkInLab to create the referral. A lipid and CMP panel is only $45. Ideally I would also track CBC (which gets all your enzymes), but that is a bit more expensive.
