A. From crossfit.com on Dec 21 2017:
20 minute AMRAP of:
10 high(er) box jumps (Rx is 36″ on the website, but just aim for something higher than you normally use)
15 DB overhead squats (partition reps as needed – note that this 15 total reps, not 15 per arm) (50/35 lbs)
20 GHD situps (for most of you, abmat sit-ups will be a better choice).
For those with very restricted overhead squat mobility, consider modifying to squatting with an empty bar, or doing goblet squats instead.
