Blood Presure?

[nazztyz06]

I have a BP moniter at home, I moniter it daily.
First think in the morning it has been bettween 140 over 85 to 90.
Now after I do a cardio session I take a reading. About 5 minutes after a 30 min of hard cardio,
it is about 110 to 120 over 70 to 75.

My question is why the difference after getting my hart rate up?

Not sure. i've got a machine too, so now you've got me thinking i need to check too.

and on a related note, why is wood so much more intense after a vigorous workout and cardio?
