Definitely a day to WATCH the demo video (Mac / Windows). The mods will be doable. This is the first running of this WOD so don't try to make your body a pretzel without trying these moves slowly and in increments during your warm up.
Complete as many rounds as possible in 20 minutes of:
3 Wall climbs
5 Parallette pass-throughs (forward + back = 1)
10 Grasshoppers (right + left = 1)
For the wall climbs, toes and chest touch the ground to toes and chest touch the wall. For the up-downs, thighs touch the ground then stand up fully. For the pass-throughs, the hips open at the front and back. For the grasshoppers, the shin contacts the opposite forearm.
For those of us feeling the approach of the holiday food season, here is some timely advice from R. Wolf's crew on staying between the lines.
And under the "a reminder is a good thing" file, this is the season when that weight gets packed on. Here's a study on how it does. Don't try some trendy quickie diet this year. Get more paleo and less processed through the holidays!
