"Whip" is the word I always use to describe how to move the jump rope on double unders. :)
20 double unders
My DUs were back today -- there were only a couple rounds where I didn't get 20 at a time. Makes me even more pissed about how the week 1 workout went down!! Argh!
Note to self -- don't attempt to do DUs in your lifting shoes again. I think that factor highly contributed to my craptastic DUs in that WOD.
