For Time 
3000m row 
100 sit-ups

Try for a hard push on the row and a steady pace on the sit-ups. I followed along with ATFS #34 strategy for the row. In the first minute take 2 power strokes and every minute thereafter, add 2 additional power strokes, finishing with 24 during minutes 12&13. Sit-ups were done in sets of 12-15.
