The original post could be written by me. All my numbers are astoundingly good, doctors say I'm as fit as someone half my age... except BP. It started climbing when I was in my early 50's. Without medication, my numbers are maybe 160/90. I commute by bike year-round, ride 5,000+ miles/year, hike, backpack, don't own a car and walk everywhere. My current doctor is pretty anti-med, and has worked with me on diet, sleep quality, and stress to get me off them. I've tried yoga, meditation, cutting beer, dropping weight, even going vegetarian for 30 days. Nothing has worked so far.
If I go out and to a hard 40k, BP is down for a day.
My mom had hypertension all her life. I'm not done trying things, but maybe it just is what it is.
