So you want a cardio finisher, why not try something with sleds, tires and a big hammer.
Its not much, but can really get your heart rate up and going, and a good fully body workout for the last 10 minute finish.
Here it is:
Sled run with 2 45 plates
10 squat jumps
10 hammer slams per side
Sled run back to beginning
