actually, 120/80 is considered High normal for a normal person. 130 is borderline hpertension, or "pre hypertension". What was your diastolic? that is really the more important of the two numbers. Your systolic pressure is the pressure created in your arteries during contraction, whereas diastolic (bottom number) is the pressure created during the relaxation phase of your heart beat. A 130 would tell me you either have a lot of stims in your diet, or have some sort of cardiovascular problem, but i'm going to assume the first, as we are on a bodybuilding website.
Also, just taking your bp once doesn't really give you an accurate representation of your BP. Were you walking fast? was it hot out? were you dehydrated? All this plays a role in blood pressure.
Ways to alleviate this?
1. cardio, low intensity at first, because cardio obviously elevates systolic BP
2. visit your doc and get checked out, because you can catch things early that can be an issue later
3. drop all stims from your diet for a while, i'd say at least a month. You'll see it come down.
My bachelor degree is in exercise science, so I do actually know what i'm talking about 8)
any questions on this or anything else physiology related, just let me know man.
