What are all those CrossFit Abbreviations?
WOD: Workout of the Day
Although CrossFit combines many other elements, one of the key characteristics is a daily workout, hence the "workout of the day". These are either done "AMRAP" (see below for definition) in a certain amount of time; or complete a circuit as fast as possible.
Hero WOD:
CrossFit Hero WODs are some of the most intense workouts that you can experience. They are intended to be performed with intense effort, in honor of our fallen Heroes. Don't think of yourself. Instead think about the Hero that has given his all for our freedom.
Benchmark WOD
Workout that is used as a baseline to measure progress, usually named after girls, such as Fran, Diane, and Grace.
EMOM: Every minute, on the minute
Another type of workout with a fixed time limit is EMOM, or every minute on the minute. These workouts are also scored as how many reps you can do overall, but note that as time goes on your rest periods will likely get shorter!
RX: As prescribed
The goal for any crossfitter is to be able to do the workouts RX'ed, or as prescribed. Since CrossFit workouts can be scaled based on abilities the goal is to work your way up to what the workout is supposed to be like. Examples of scaling could be using a lighter weight, completing less repetitions, or doing assisted pull-ups.
PR: Personal Record
With any workout or lift, the goal is to strive for a PR, or personal record. This is a great way to measure progress and track results!
