I got a taste of those yesterday after my workout. "runner's high" indeed! LOL I was in very high spirits, almost manic once I was done, and it took a while to wear off... I haven't felt that good in a long time. I want feel like that again. So I think I'll try to do this workout again tomorrow after work.
I felt energetic, and giggly and happy. It may have been the endorphins, but it also was a sense of accomplishment, I think. The feeling of finally getting up off my butt and MOVING!
