WOD: workout of the day; the intensity segment lasting an average of 10-20 minutes
AMRAP: As many roundsreps as possible; Perform the series of exercises without stopping for the set amount of time. Keep track of your rounds/reps.
RFT: rounds for time; Perform a set number of rounds of the exercises - stop time when you have finished.
RX: as prescribed; This means you did the workout as it was written, weight load, reps, etc… Please know that CrossFit workouts are programmed for the elite athlete and then scaled down. Only a fraction of athletes consistently perform workouts as prescribed. What you see on the board is not necessarily what YOU will be doing that day — the purpose of the workout will not change, just be adapted to your current fitness level.
