Neuro Training Dosage: When More Reps Become Too Much

  Why another five reps can turn a useful neurological input into the wrong dose

What This Article Answers

Can you do too much of a neuro drill even when the drill is helping? 

Why can a positive reassessment start getting worse when you keep adding repetitions? 

How do you know when you have given the nervous system enough input? 

 

The Direct Answer

Yes, you can absolutely do too much of a neurological exercise. One of the easiest mistakes to make in neuro training is assuming that if five repetitions helped, ten must help more.

Sometimes they will. And sometimes the sixth repetition is where the result begins to disappear. The goal of neurological training is not to give the client as much stimulation as they can tolerate. It is to find an appropriate dose of input that produces a useful response and then use the reassessment to decide what happens next.

 

That means there comes a point when the practitioner has to ask a surprisingly difficult question…

 If the reassessment already improved, why am I still doing the drill? 

More is not automatically better.

Sometimes more is simply more.

And sometimes more is exactly what turns the right input into the wrong dose.

Most Practitioners Have Been Taught to Think in Sets and Reps

This makes sense when everyone has been trained from a biomechanical educational perspective. 

Most people entering applied neurology come from physical therapy, strength and conditioning, personal training, rehabilitation, Pilates, chiropractic, movement coaching, or another field where repetition is part of the process.

We are accustomed to prescriptions that look like:

• 3 sets of 10
• 2 sets of 15
• Hold for 30 seconds
• Repeat five times
• Complete three rounds

Those numbers give the practitioner and the client something concrete to follow.
Our biomechancial educational frameworks have taught us prescriptions to follow. 

The problem is that neurological input does not always behave neatly inside predetermined numbers.

Over-inputting might look something like this:

• The client performs the drill.

• You reassess shoulder rotation. It improves noticeably.

• You add five more repetitions.

• You reassess again. The improvement is smaller this time.

• You add another five repetitions.

• You reassess one more time. Now they are right back where they started.

The drill worked.

The problem was not the exercise. It was continuing after you had already gotten the result.

What happened?

It is tempting to conclude that the original improvement was random or that the drill stopped working.

There is another possibility.

You may have continued past the useful dose. 

This is why we go into detail around the minimal effective dose during our mentorship.
 

Neuro Training Has a Dose-Response Relationship

Every neurological exercise provides some form of input to the nervous system.

The dose of that input can be changed through variables such as:

1.  Intensity 
2.  Duration 
3.  Repetitions 
4.  Speed 
5.  Range of motion 
6.  Complexity 
7.  Frequency 

Changing any of those variables changes the amount of stimulus the nervous system has to process.

The important part is that the dose is not determined only by what the practitioner sees on paper.

It is also determined by how that individual nervous system perceives the input.

Five head movements may be almost meaningless to one client and overwhelming to another.

Ten seconds of a visual drill may create a significant change for someone who has never trained that system before, while another person may require substantially more stimulus before the reassessment changes at all.

The number is not the dose by itself.

The dose exists in relationship to the nervous system receiving it. 

That is why fixed prescriptions can become problematic.

There Is a Sweet Spot

Think about neurological training as having a useful window.

At one end, there may not be enough stimulation to create a noticeable response.

The practitioner applies the input, reassesses, and essentially nothing changes.

That does not necessarily mean the idea was wrong.

The dose may simply have been insufficient.

Increase the appropriate variable and eventually the nervous system may reach a range where the stimulus creates a useful response.

Pain decreases.

Rotation improves.

Balance becomes easier.

Movement feels smoother.

Strength changes.

Breathing becomes less effortful.

That is the response you were looking for.

But here is where things get interesting.

The curve does not necessarily keep climbing because you keep doing more.

Eventually you may reach a point of diminishing returns.

The client is doing more work but getting less benefit from it.

Continue pushing beyond that point, and the nervous system may begin responding negatively to an input that was useful only a few repetitions earlier.

That creates a very different way of thinking about exercise selection.

Our mentorship students no longer ask...

How many reps should this person do? 

They think minimal effective dose...

How much of this input does this person need right now? 

The Nervous System Does Not Give Bonus Points for Extra Reps

This is where our training background can work against us.

There is often an instinct to finish the set.

Seven reps were prescribed, so we do seven.

Thirty seconds are on the timer, so we finish thirty seconds.

Three rounds are on the sheet, so we complete all three rounds.

But what if the result you wanted happened after eight seconds?

What if the client's rotation improved after three repetitions?

What if their balance became significantly better after the first round?

The nervous system does not care that there are seven reps written on your program.

The reassessment is telling you something.

A positive change gives you evidence that the nervous system responded favorably to the input you just provided.

Continuing automatically because there are more repetitions left assumes something you have not actually tested...

That additional input will create an additional benefit. 

It might.

But now you need evidence.

Diminishing Returns Can Be Easy to Miss

Imagine a client begins with limited cervical rotation.

You establish the baseline.

They complete a neurological exercise.

You reassess.

Their rotation improves significantly.

Great.

You repeat the exercise.

The improvement is still there, but slightly smaller.

You repeat it.

Very little additional change.

Again.

Now rotation has actually decreased.

The drill did not suddenly become a bad drill.

 The nervous system may simply have crossed from a useful amount of stimulation into an excessive amount.

This is a thought process we single out continually in our live teaching formats,  because without repeated reassessment, the practitioner may never notice where that transition occurred.

They only assess at the beginning and the end.

The client started with limited rotation.

Twenty repetitions later, they still have limited rotation.

The conclusion automatically becomes...

"That exercise didn't work." 

But perhaps it worked extremely well after the first five repetitions.

You just kept going.

A Negative Response Does Not Always Mean You Chose the Wrong Drill

This is another reason assess and reassess matters so much.

A negative response can mean several things.

The input might have been inappropriate.

The exercise may have been too complex.

The timing might have been poor.

The client's nervous system might already have been overloaded.

Or the drill may have been appropriate and delivered at the wrong dose.

Those are two very different conclusions for a practitioner to come to.

If a client responds positively after three repetitions and negatively after twelve, the information is not necessarily..

Never use this drill again. 

It may be..

Three repetitions were useful. Twelve were not. 

That helps the practitioner become much more precise.

Instead of labeling exercises as good or bad, we begin paying attention to the relationship between the input, the dose, the client's current state, and the response.

Two Clients Can Need Completely Different Doses

There is another complication.

You cannot always predict someone's neurological dose simply by looking at them.

One person may respond strongly to a tiny amount of visual stimulation.

Another may need much more.

A highly trained athlete may require considerably more proprioceptive or movement input before producing a meaningful change because that system has years of experience and adaptation behind it.

Take the same athlete into an unfamiliar visual or vestibular challenge, and the response might be completely different.

The useful window may suddenly become very narrow.

This is why someone's tolerance for physical training does not automatically tell you their tolerance for every neurological input.

A client may tolerate an hour of hard strength training and become symptomatic after a relatively small amount of vestibular work.

Their fitness level did not suddenly disappear.

You changed the sensory system being challenged. 

The Same Client May Need a Different Dose Tomorrow

Once you find a useful dose, it is not permanently fixed.

The nervous system showing up on Tuesday is not necessarily in the same state as the nervous system you worked with last Friday.

Sleep may be different.

Stress may be higher.

Training load may have changed.

Pain may have increased.

Recovery may be lower.

The client may be getting sick.

They may be more emotionally overwhelmed than usual.

Their available capacity has changed.

That means five repetitions that created a great response last week may be too much today.

Or they may not be enough.

This is one of the reasons neurological training is difficult to reduce to a rigid protocol.

The protocol cannot see the client standing in front of you.

The reassessment can.

Stop Asking, "How Much Can They Handle?"

A shift happens when we start thinking about the minimum effective dose.

Instead of trying to determine the maximum amount of work a client can tolerate, we become interested in the smallest useful amount.

• If more stimulus improves the reassessment, there may be a reason to continue.

• If additional repetitions stop improving the response, you have learned something about the dose.

• If the reassessment starts getting worse, you have learned even more.

• If the smallest dose creates the desired change, there may be no reason to keep adding more.

That does not mean clients should never be challenged or that training should always feel easy.

It simply means every additional dose should have a reason behind it.

The goal is not to exhaust the nervous system into adaptation.

The goal is to give it enough information to produce the change you are looking for.

Reassessment Tells You When to Stop

This is one reason reassessment should not simply happen at the end of the session.

It helps guide the session.

A basic process can look like this…

1. Establish a baseline

Choose something meaningful and repeatable.

It could be pain, range of motion, balance, strength, movement quality, coordination, breathing, or another relevant measure.

2. Apply an input

Choose a drill based on what you believe may be influencing the client's current output.

3. Reassess

Did the baseline improve, stay the same, or become worse?

4. Adjust the dose

If nothing happened, perhaps the input needs to change.

Sometimes that means increasing the dose.

Sometimes it means changing the exercise.

If the reassessment improved, determine whether additional input is actually necessary.

5. Reassess again

Do not assume the next repetition is helping just because the previous one did.

Let the response guide the dose.

This turns the session into an ongoing conversation with the nervous system rather than a predetermined collection of sets and repetitions.

Sometimes You Should Stop While You're Ahead

This can feel strange at first.

A client performs three repetitions.

Their shoulder suddenly moves better.

They feel less discomfort.

The movement feels easier.

And you say…

"Great. We're done with that one." 

Only three reps?

Yes.

Because the objective was NOT to complete ten repetitions.

The objective was to provide an input that created a useful response.

You accomplished it.

There may be circumstances where you intentionally continue training that system to build capacity, resilience, endurance, or skill.

But that should be a decision.

Not a habit.

There is a big difference between progressively training an input and automatically doing more because more feels productive.

The Drill Is Only Part of the Prescription

Applied neurology becomes far more useful when practitioners stop thinking only about exercise selection.

Choosing an appropriate drill matters.

So does:

•  How much you use 
•  How quickly you perform it 
•  How complex you make it 
•  When you introduce it 
•  How frequently you repeat it 
•  How the client responds 
•  When you decide to stop 

A brilliant exercise delivered at the wrong dose can produce a poor result.

A simple exercise delivered at the appropriate dose can sometimes produce an impressive one.

That is why neurological training is less about memorizing the perfect exercise and more about learning to make decisions from the information the client gives you.

Before You Add Another Five Reps, Reassess

The tendency to do more is understandable.

More training feels productive.

More repetitions feel thorough.

Completing the entire prescribed set feels like we finished the job.

But the nervous system is not obligated to follow the program we wrote.

It responds to the information it receives.

The useful dose might be two repetitions.

It might be twenty.

It might change tomorrow.

The practitioner does not need to guess.

Assess.

Apply the input.

Reassess.

Then make the next decision.

Because once the result you were looking for has already occurred, there is one question worth asking before doing anything else…

Why am I giving them more?
