Her premises is flawed. Workout of the day is a prescribed set of movements with a particular goal in mind. You scale and change the weight movement and reps with your coach each day based on skill, and ability. The author seems to think there is no wiggle room. Also most gyms week have several workout of the days to pick from based on experience level.

The mark of a good crossfit gym is individualization. This author seems to think those kinds of gyms don't exist.
