RX Is a Prescription, Not a Prize

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

You look at the workout. There are 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.

Because 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. Movement quality. Experience. Sleep. Injury history. Even how you're feeling that day.

RX reduces all of that to yes or no. And humans love a clear threshold.

So someone chooses the prescribed 60kg barbell because they can lift it. The workout was supposed to take eight minutes. It takes them seventeen. Every set becomes singles. Their technique deteriorates. They spend half the workout looking at the bar.

But they got RX.

Meanwhile, someone else uses 45kg, moves beautifully, keeps the intensity high and finishes in eight minutes.

Who did the workout better? Almost certainly the second person.

You can RX the movements and completely miss the workout.

CrossFit's own coaching guidance is remarkably clear on this. The prescribed version is generally based around higher-level athletes, while scaling should preserve things like the intended loading, movement pattern and duration of the workout.

Its guidance on stimulus makes the same point: a short, intense workout should remain short and intense. If the prescribed load turns it into a long grind, you're no longer doing the same training session.

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.

Your body doesn't know whether you finished the final round. And it definitely doesn't know whether there was a little RX symbol next to your score.

It knows load. It knows speed. It knows range of motion. It knows muscular tension, cardiovascular demand, fatigue and recovery.

It knows the stimulus. That's what training is.

If today's workout is meant to be a sprint and choosing RX makes it a 25-minute endurance event, you've changed the stimulus. If the pull-ups are supposed to be performed in quick sets but you're doing one every 30 seconds, you've changed the stimulus. If you're lifting a weight that means your movement quality falls apart, you've changed the stimulus.

Your ego might prefer the RX version. Your physiology couldn't care less.

We already put enough pressure on ourselves

This matters because people are already far less confident in gyms than we sometimes assume.

The 2026 Global Fitness Report found that 37% of people don't feel confident working out. Among people considering strength training, 50% say they'd feel out of place in the weights area and 54% don't know where to start. Even experienced lifters report uncertainty around progression, load and exercise selection.

Then we add another visible hierarchy.

RX at the top. Scaled underneath.

It's not difficult to see how people start interpreting those words as good athlete, less good athlete. That's not what they mean.

Scaling isn't an admission that you aren't fit enough. It's how good programming becomes your training programme.

Even CrossFit has explicitly pushed back against the "RX'd or nothing" mentality, arguing that refusing to scale can mean missing the intended stimulus altogether.

It's also why every class runs a coached Gymnasium Start track for anyone who's new. Scaling isn't something you have to ask permission for. It's built in from session one.

Scaling isn't making the workout easier

This is probably the biggest misunderstanding.

Scaling doesn't mean make it easier. It means make it appropriate.

Sometimes that's less weight. Sometimes fewer reps. Sometimes it's changing a highly technical movement for one you can perform properly. Sometimes it's reducing the distance so you can maintain the intended pace.

And sometimes, for a very capable athlete, the appropriate version might actually be harder than the prescription.

The objective isn't to make everybody's workout identical. It's to make the training effect appropriate.

Twenty people can therefore be doing slightly different versions of the same workout and all be training exactly as intended. That's good coaching, and it's the whole idea behind class-based training scaled to the individual.

“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 is a time to RX

None of this means standards don't matter. They absolutely do.

There are times when you should find out what you've got. Competitions. The CrossFit Open. Benchmark workouts. Testing days.

Those are useful precisely because the standard doesn't move. You meet it or you don't. Then you train, improve and come back again.

But that's testing.

Most of your week is training. 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.

On test day, test. On training day, train.

The best athletes scale

Watch experienced athletes closely and something interesting happens. They're often much less emotionally attached to RX.

They know when a weight is wrong. They know when a skill will derail the session. They know when yesterday's training, tomorrow's training or an upcoming competition changes what they should do today.

They'll take 10kg off the bar without having an existential crisis about it. Because they're not trying to win the whiteboard. They're trying to improve.

That's a very different mindset.

The beginner often thinks scaling is evidence that they're not good enough. The experienced athlete understands that choosing the right scale is part of being good.

“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

So next time you see a workout, don't start with: can I RX this?

Start with: what is this workout supposed to do?

Is it meant to be fast? Heavy? Continuous? Technical? A long aerobic grind? Short bursts with recovery?

Then ask: what version allows me to train that today?

Maybe it's RX. Maybe it isn't.

That little label beside your score is useful information. It just 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.
