Use this pace to get a sense of how you should pace yourself.
If you did this exactly, you'd end with 10 rounds. That would be a baseline for this. If this was too easy, see if you can do without the rest (or plug the rest in every other round) or maybe every movement in 0:20. For most people, this workout will be won by those who strategize smartest in their pacing. Be smart, don't go in blindly.

For use of the dumbbells and depending on class size, we may have to run two heats for this workout. Be prepared to judge/count reps for someone as they will do the same for you.
