Five rounds, each for time 
300m SkiErg
12 DB Thrusters @ 35lbs
Rest 1:1

1:57, 2:07, 2:17, 2:34, 2:51

This is a simple, but devastating combo. My times fell off hard after the first couple of rounds and I switched to rest as needed to get my heart rate down. Need to spend some time beforehand getting primed for high-intensity by elevating the heart rate rapidly so I am more prepared when it happens in the actual workout. See here for some examples.
