This workout is meant to feel light. You should move constantly through the workout (big sets) with very little rest. If you find that you need to take big rest breaks, drop the volume (do the "Dirty Thirty") or the load. Before you start, pick the movements from the WOD that are in your wheelhouse. When you get to a movement that you can crush, go hard. A steady pace through all the movements in "Filthy Fifty" could result in a slower overall time.
