First off, the connotation of this workout needs to be defined:
nasty [ˈnɑːstɪ]adj -tier, -tiest
1. unpleasant, offensive, or repugnant
2. (of an experience, condition, etc.) unpleasant, dangerous, or painful (ie: a nasty wound)
Now that we have that settled, this is probably one of the most balanced CrossFit benchmark WODs. Gymnastics, strength, and metabolic conditioning all wrapped up into one nasty workout.
The other advantage is that it can be done inside. Hopefully we'll be back outside next week... but with temps near 106 through the weekend, we just don't want anyone to die. :)
3 Rounds, for time:
50 Air Squats
10 Hang Power Clean (135lb)
If you cannot perform the Muscle-Up, you may use a 3:1 substitute of pull-ups and dips. That is 3 pull-ups and 3 dips per muscle-up.
