Examples:
..... My first workout was at home. I did 30 minutes on the inclined treadmill, then I did The Firm Calorie Killer with Nancy Tucker. My heart rate was through the roof the whole time. I burned 651 calories. And I sweated like a pig , which pretty much goes without saying.
..... I was sweating like a pig after the workout today, so I decided against doing a Firm DVD when I got home. I couldn't wait to shower!
..... What a disgusting dump this was. I sat down and there were a bunch of flies everywhere, and it was so hot I was sweating like a pig.

.....By the end, I was sweating buckets, my breathing was more ragged then on a threadmill, and I had what a friend calls "Starters runner's cough". Took a Halls like he said and it was fine after a bit.


Example from NCIS, s02e01:


Tony: Anyone? I mean, anyone know when the air conditioning's getting fixed? What about the name of the genius who invented windows that don't open? What are we, on a space ship? Windows should open!
Kate: Oh, have you been working out?
Tony: All summer long...thanks for finally noticing.
Kate: No, I mean right now, 'cause you're sweating like a pig and it's not very attractive.
