How to read a WOD: Rx, scaled and foundations explained
The shorthand on the whiteboard looks like code at first. It is simpler than it appears.
Walk into a CrossFit box on your first day and the whiteboard can read like a foreign language. WOD, AMRAP, EMOM, Rx, scaled, a list of movements and numbers. None of it is complicated once you know the vocabulary. Here is what the whiteboard is telling you.
The basics
WOD stands for Workout of the Day, the session everyone in the class will do. It is usually built from a few common formats:
- AMRAP: As Many Rounds (or Reps) As Possible in a set time. You repeat a circuit and count how far you get.
- For time: complete a set amount of work as fast as you can. The clock is your score.
- EMOM: Every Minute On the Minute. At the start of each minute you do a set piece of work, then rest until the next minute begins.
- Rounds for time, often written like 5 rounds for time, meaning you repeat the listed work five times against the clock.
Rx, scaled and foundations
These three words describe how heavy or hard your version of the workout is, and they matter more than any of the formats above.
Rx, short for as prescribed, means doing the workout exactly as written: the listed weights, the listed movements, the full standards. It is the benchmark version. Completing a workout Rx is a milestone, not a starting expectation.
Scaled means you adjust the workout to suit your current ability while keeping its intent. You might use a lighter weight, fewer reps, or an easier version of a movement, for example ring rows instead of pull-ups, or a box-assisted push-up. Scaling is not cheating. It is how the same workout serves a complete beginner and a seasoned athlete in the same class, each getting an appropriate stimulus.
Foundations, sometimes called on-ramp or fundamentals, refers to the introductory programme most boxes run for newcomers. It teaches the core movements at a gentle pace before you join the regular classes. If your box offers it, do it. The time spent learning to squat, hinge and press well pays back for years.
How to choose your version
The honest answer for almost every beginner is: scale. The aim of a workout is the training effect, the right amount of effort and stimulus, not the letters next to your name on the board. A well-scaled workout that you complete with good technique and real effort beats an Rx attempt that leaves you grinding out broken reps with bad form. A good coach will help you pick weights and movements that keep the intended challenge while keeping you safe.
Rx is a destination you earn over time, not a starting line. Scale honestly, train consistently, and the heavier versions come on their own.
Read the whiteboard, ask the coach what the workout is meant to feel like, choose a version that matches where you are today, and get to work. Within a few weeks the shorthand will feel like second nature.
