50-35-20 reps for time of:  
Sit-ups

*100 Ft Sled Push after each set of sit-ups. Men use 4X45lb plates.

21:37 

Notes: I mixed up the workout in my head and did a set of 5, a set of 3 and a single prowler push after each set of sit-ups. Loaded the prowler with 202lbs (2X45, 1X25). This was a heavy load. I was walking the sled at a medium pace -- definitely could not have run with this load. Sit-ups were touch ground above head at bottom of rep and touch sandbag in front of feet at top of rep.
