WOD (Workout of the Day)

WOD: what is it?

The WOD is the organising unit of CrossFit and of most functional fitness gyms that followed it. Everyone in the class does the same workout on the same day, the result goes on a whiteboard, and the workout is programmed to be finished rather than merely attempted. Two design features do the heavy lifting: the workout is scored, which turns intensity into something visible, and it is shared, which turns training into a social event. Those two things together explain most of why the format retains people so well.

The common WOD structures

Almost every WOD is one of a handful of shapes. The shape determines what is fixed and what is variable, and therefore what the score means.

Reading and writing a WOD

A WOD is written in a compact shorthand: the format, the clock, the movements, the loads and the rep scheme. "21-15-9 thrusters 43/30 kg, pull-ups, for time" tells an experienced athlete everything they need. The numbers separated by a slash are the prescribed loads for men and women respectively.

When you write one yourself, decide the intended stimulus first and the movements second. A seven-minute sprint, a twenty-minute grind and a heavy strength piece are three different sessions, and the loads and rep schemes have to serve whichever one you picked. The most common programming failure is a workout that was meant to be fast but is loaded heavily enough that everyone shuffles through it.

• Write the intended time domain at the top before choosing a single movement.
• Set a time cap. Uncapped workouts turn into a grind for exactly the people who most need the stimulus.
• Give a scaling option for every movement, in advance, not improvised at the whiteboard.
• Avoid stacking two heavily fatiguing movements for the same muscle group late in a workout.

Scoring, and what the score is worth

The score makes intensity measurable and gives a retest a meaning. Repeat the same WOD three months later, under the same conditions and standards, and the change in score is real information about fitness in that time domain.

The score also has a cost. It creates a pull toward rushing reps, cutting range of motion and lifting a weight that is beyond an athlete on that day - all of which make the score better and the training worse. The counterweight is enforcing movement standards out loud and treating a scaled score as a legitimate score, not an apology.

Programming WODs across a week

The daily variety needs a weekly structure behind it or it becomes random. A reasonable frame is to vary the time domain across the week - one short and brutal, one in the ten-to-twenty-minute range, one longer aerobic piece - and to vary the dominant modality so that the week covers pushing, pulling, squatting, hinging and cyclical work.

Watch the accumulated load on the same tissues. Three days in a row containing high-rep pull-ups and kipping is not variety, whatever the workouts look like on paper. Programming across the week, not the day, is what separates a coached gym from a whiteboard of ideas.
