AMRAP 2 minutes x 3 rounds 
30 abmat butterfly sit-ups
max calories on assault bike in remaining time
Rest 5:00 between rounds

Put in a good warmup on the rower and hammer the bike. I reduced the volume on the sit-ups to 25 reps for the last two rounds as I wanted to have at least 30 seconds on the bike. Came out too conservative the first round and only posted 7 calories. The second and third rounds I was able to get 13 calories each. Get that bike north of 90+ RPMs.
