Crossfit Open 17.2 - Good Workout

This work out really could be a fun workout except it is a Crossfit Open workout that will kill alot of people.  The RX workout is just a beast.  50lb lunges and MU are hard just doing them once.  Most people have never done a MU but pushed them self to get one in the open games.  They should be super proud and continue to work on it for next year.  O, and TTB are a killer.
The scaled version is not aweful, except for the two rounds of 16 chest to bar.  That is hard for the average joe.  I got through 2 full rounds and a couple more lunges.  I could have done a few more reps but that would have been about it.

This is a work out I want to repeat in a few months to see how far I have come in my fitness.  17.1, I do not want to ever do again.
