2013 Crossfit Open 13.3 Workout

12 min AMRAP

150 Wallballs 20/14

90 Double unders

30 Muscle ups

If you complete the 30 MU’s, you return to wallballs.

I started off well by making it to 22 before a quick break. I just didn't have the endurance to keep going. I did no-rep 4 or 5 times due to not hitting the height.
This one is absolutely a "one and done" WOD.
