Every 75 seconds do:
3 power cleans (65#)
3 box jumps
3 power cleans (65#)
3 box jumps

I made it through 20 rounds, on the last one I did 3 power cleans, 3 box jumps, 3 power cleans, 1 box jump.

It was a pretty cool workout. Pretty fun too. Especially since instead of jumping on the box, I jumped on one of the tires.
