I'd think modest exercise would be ok before the blood draw as long as your hydration status isn't significantly affected. My understanding is that PSA and prolactin are the tests that may be affected by sex in the day or so before.
I am not a medical doctor; any suggestions are meant to be discussed with your doctor.
