Did one yesterday that I've never done before: Set the stopwatch running and in the first minute did 1 lat pulldown (105 lbs on Fanfare's machine) and one bench dip. In the second minute did two each. Continued until I could not complete the required reps in a minute, which came at 8 reps each. (That it, completed 8, could not complete 9.) Stopped clock at 9:12.
Finished the entire workout AND shower in less than 30 min.
