As I mentioned, we don't have a CrossFit box in my town, just a gym with some random equipment. I tried to create my own Workout of the Day for December 26 on the theme of Boxing Day. I wasn't sure whether to concentrate on boxes or boxing, so I tried to do both:
box jumps 1/2 height
box jumps full height
Only I discovered that I can't do windshield wipers or speed bag due to lack of coordination (I kept falling off the bench, and there was no bar appropriate for doing hanging wipers). So it was sort of a bust, but not a bad concept.
