Today I was a little sick but I still went to the gym to do my workout. I had a really annoying consistent headache.
A friend of mine warned me not to do all the sets because i could damage my brain from high blood pressure. Well he had no convincing argument so I didn't stop. However I am wondering if it is true and if there are other things I should consider.
What are the dangers of working out with a headache apart from passing out?
