A bunch of the Crossfit benchmark workouts have girls' names. So in this particular case, Cindy isn't a real person, she's a workout, and those "rounds" I did with her consisted of pull-ups, push-ups and squats. The workout is as many rounds as possible in 20 minutes of 5 pull-ups, 10 push-ups, and 15 air squats. I got 20 rounds. One round per minute. That's 100 pull-ups, 200 push-ups, and 300 squats in less time than it takes to listen to one song at a Phish concert. I was gassed. I also got on the record board again. This time, the guy I knocked off is the stud of my gym.* He has almost all of the records. I really can't say enough about this stuff. Doing 100 pull-ups in 20 minutes seemed unfathomable to me a few months ago.
*Full disclosure: he had been lifting heavy for about an hour before he did the workout. He got 19 rounds + the pull-ups and push-ups. If he tried "Cindy" again he'd take his record right back.
