21:02 (8 rounds, unanchored sit-ups; Avg.HR=169, Calories=319)
Planned to pack it at 6 rounds (which I got in 14:15), but decided to knock out a couple more. Got 90 pull-ups and 90 dips in 17:36 previously, so I'm pretty happy with this time, especially since the PU and dip bars are not next to each other at the new gym.
