RX Is a Prescription, Not a Prize

The little RX next to your score was meant to describe the workout. Somewhere along the way, it became a status symbol.

There are very few letters in fitness with as much emotional weight as RX.

You look at the workout. Pull-ups, a barbell, maybe some handstand walking. Before you've even thought about what the session is trying to achieve, the question arrives: can I RX it?

And if you can't, there's often a tiny sense that you've somehow failed.

You haven't. RX doesn't mean good. It means as prescribed. That's it.

RX is a prescription. Not a prize.

The badge changed the behaviour

The problem with RX is that it turns something continuous into something binary. Fitness has thousands of variables: strength, skill, speed, work capacity, sleep, how you're feeling that day. RX reduces all of that to yes or no.

So someone chooses the prescribed 60kg barbell because they can lift it. The workout was meant to take eight minutes. It takes them seventeen, in singles, technique falling apart. But they got RX.

Someone else uses 45kg, moves well, keeps the intensity high and finishes in eight. Who did the workout better? You can RX the movements and completely miss the workout.

CrossFit's own coaching guidance says the same thing: the prescribed version is built around higher-level athletes, and the adjusted version should preserve the intended load, movement pattern and duration. Keep a short, intense workout short and intense. Turn it into a long grind and it isn't the same session anymore.

Your body doesn't know you got RX

We've written before about why the finish line doesn't matter as much as you think. Same idea here.

Your body doesn't know whether you finished the final round, and it definitely doesn't know there was a little RX symbol next to your score. It knows load, speed, range of motion, muscular tension, fatigue. It knows the stimulus. That's what training is.

Change the load, the pace or the range of motion enough and you've changed the stimulus, RX or not. Your ego might prefer the RX version. Your physiology couldn't care less.

Adjusting isn't making it easier

This is the biggest misunderstanding. Adjusting doesn't mean easier. It means appropriate.

Sometimes that's less weight, fewer reps, or swapping a technical movement for one you can do properly. Sometimes it's shortening the distance so you can hold the intended pace. For a very capable athlete, the appropriate version can actually be harder than the prescription.

The goal was never to make everyone's workout identical. It's to make the training effect appropriate, which is the whole idea behind class-based training scaled to the individual. Twenty people, twenty slightly different versions of the same workout, all training exactly as intended. That's good coaching.

It's also why we're not precious about people asking. The 2026 Global Fitness Report found that half of people considering strength training would feel out of place in the weights area, and over a third don't feel confident working out at all. Add a visible hierarchy — RX at the top, everything else underneath — and it's easy to see how "adjusted" starts to read as "less good." It isn't. That's why every class runs a coached Gymnasium Start track for anyone who's new: the right version isn't something you have to ask permission for.

“I've been coming to gymnasium for 3 years now and they've taken their ethos, coaching style and all-abilities class-led training along to Brixton.”

There's still a time to RX

Standards matter. Competitions, the CrossFit Open, benchmark workouts and testing days are useful precisely because the standard doesn't move. You meet it or you don't, then you train, improve and come back.

But that's testing. Most of your week is training, and confusing the two is where people get into trouble. You don't need to prove your fitness every Tuesday evening. You need to build it.

The best athletes adjust

Watch experienced athletes closely and something interesting happens: they're far less emotionally attached to RX. They know when a weight is wrong, when a skill will derail the session, when yesterday's or tomorrow's training changes what they should do today.

They'll take 10kg off the bar without a second thought, because they're not trying to win the whiteboard. They're trying to improve. The beginner often thinks adjusting is evidence they're not good enough. The experienced athlete knows that choosing the right version is part of being good.

"RX describes the workout. It never described you."

“Whether you're a beginner or want to step things up and take it to the next level with CrossFit, the gym has a great team of coaches, friendly and sociable members.”

Change the question

Next time you see a workout, don't start with can I RX this. Start with: what's this workout supposed to do? Fast, heavy, continuous, technical, a long grind, short bursts with recovery?

Then ask what version lets you train that today. Maybe it's RX. Maybe it isn't. That little label is useful information. It isn't an identity, and it certainly isn't the goal.

The best athletes aren't the people who RX everything. They're the people who know exactly when not to.
