So I have a quick exam/blood draw scheduled for Thursday, and the nurse just told me to day to not do any hard exercising that morning as it would make my blood pressure go up. I was planning about a 30 mile ride in the morning. Is her concern valid, should I skip my ride? Normally my BP is on the low side anyway, and I'm not really wanting to cancel on my ride partner. Curious to see if any of you are aware of how much exercise would affect it... I'd be doing the exam about 2 hours after finishing the ride, if that makes a difference.
