My cycling exercise (not quite ready to call it training, but I'm getting close) has brought my resting heart rate down to the 58-62 range. From what I can read, that is likely responsible for the fact that I often get light headed if I stand up quickly. Seems to be mostly in the evenings. Anyone else experiencing this after embarking on a serious exercise regimen?
I recently had a nuclear stress test, and got a green light to go for it as hard as I'd like.
