I don’t exercise a lot but when I play tennis and I am happen to be pushing to my limits (2 hrs, no breaks almost), there is a point when I get a sudden rush of pleasure for about a minute when I get a lot of goosebumps. Afterwards, I am in such a good mood and feel like I can push for a little bit more before being totally done. I am not sure if something like this is what people refer to as exercise highs?
