If I Hear “Movement Doesn’t Happen in Isolation” One More Time...
I’m going to say something that might ruffle a few feathers.
I’m so over hearing people say:
"Movement doesn’t happen in isolation."
DUH.
Of course it doesn’t.
Nobody is arguing that a squat happens at one joint or that your golf swing is powered by a single muscle. We all understand that human movement is integrated.
That’s not the debate.
The problem is what sometimes gets implied by that statement:
Because movement is integrated, we should never isolate or specifically address one part of the system.
And I don’t agree with that at all.
Movement is integrated. That doesn't mean every intervention has to be.
Sometimes one specific limitation is holding the entire movement back. And when that happens, addressing it directly can be exactly what the person needs.
Sometimes Coaching the Pattern Isn't Enough
I was working with a client who was struggling with their squat.
Their knees were collapsing inward and their low back was getting uncomfortable during the movement.
There are a lot of ways a coach could respond.
Cue the knees harder. Add a band. Change the tempo. Give them a goblet squat. Modify the stance. Keep rehearsing the pattern and hope repetition cleans it up.
And sometimes one of those things works.
But in this case, the squat itself wasn't where I wanted to spend most of our attention.
When we looked closer, there were mobility limitations at the hips and a lack of usable range at the ankles.
So we stripped things back.
We worked specifically on the hips. We addressed the ankle mobility. We gave the client access to positions they didn't have before.
Then we went back to the squat.
Things started cleaning up.
Not perfect.
But noticeably better. And fast.
That's the point.
Sometimes improving the integrated movement means addressing one piece of it directly.
Sometimes You Need to Isolate the Limitation
Think about a bike wheel.
The entire wheel works as a system. Every spoke contributes to how that wheel functions.
But if one spoke is creating the problem, you don't go around adjusting every other spoke simply because:
"The wheel doesn't work in isolation."
You address the spoke that needs attention.
The whole system matters.
But sometimes one piece of that system is what's holding everything else back.
Human movement can work the same way.
If someone can't rotate well, maybe the limitation is at the hips. Maybe it's the thoracic spine. Maybe it really is the shoulder or neck you're looking at.
If someone struggles with a squat, maybe the ankle is limiting them. Maybe it's the hip. Maybe mobility isn't the issue at all and they need better control, strength, coordination, or simply a different exercise strategy.
That's coaching.
Look at the whole person.
Look at the movement.
Figure out what's limiting it.
Then don't be afraid to address that piece directly.
Don't Just Keep Loading the Workaround
This is where I think coaches can get into trouble.
If someone repeatedly struggles to access the position required by an exercise, simply adding more load or more complicated cues may not solve the underlying limitation.
You're asking the body to perform a movement it may not currently have enough access to.
And the body is incredibly resourceful.
It will figure something out.
It might change the range. Change the position. Borrow movement somewhere else.
Find a workaround.
That doesn't automatically make the movement "bad" or mean someone is destined for an injury.
But as coaches, we should still be curious.
Why is this person moving that way?
Is there a mobility limitation influencing what we're seeing?
Is it stability or strength?
Is it coordination?
Is the exercise simply not a great fit for this person right now?
Or is there something outside our scope that needs to be evaluated by an appropriate healthcare professional?
The goal isn't to assume mobility is always the answer.
The goal is to identify what's limiting the movement and choose the right tool.
Sometimes that's an integrated exercise.
Sometimes it's very specific mobility work.
Integrated Movement and Isolated Training Can Coexist
This is where our industry loves creating false choices.
Compound exercise or isolation exercise.
Strength or mobility.
Movement patterns or individual joints.
Integrated training or corrective work.
Why do we have to pick one?
Sometimes I want the whole system working together.
Sometimes I want one joint moving by itself.
Sometimes I want a highly integrated loaded movement.
Sometimes I want five minutes of very specific work at an ankle because that ankle is limiting everything I'm trying to accomplish above it.
Those ideas don't contradict each other.
They complement each other.
A coach's job isn't to pledge allegiance to one methodology.
It's to choose the right tool for the person standing in front of them.
Mobility Is Not the Opposite of Strength
This is another idea worth clearing up.
Mobility and strength are not competing philosophies.
I don't want somebody mobile instead of strong.
I want them mobile and strong.
Mobility gives us access to movement.
Stability and control help us own that movement.
Strength allows us to produce and resist force through it.
Then we can build power, speed and eventually higher-level skill on top.
Mobility → Stability → Strength → Power → Speed → Skill
But these qualities don't live in perfectly separate boxes.
Strength training can improve mobility.
Mobility work requires control.
Loaded exercises can develop stability.
Skill training can reveal limitations we didn't see in an isolated assessment.
That's why the sequence is a framework, not a rulebook.
The point isn't that we must complete one stage before touching the next.
The point is that if something underneath the movement is limiting what happens above it, we should be willing to address it.
Don't Get Trapped by Training Dogma
This is probably the bigger lesson.
Don't become the coach who believes everything needs to be isolated.
But don't become the coach who refuses to isolate anything because "the body is a system."
Don't assume every limitation is mobility.
Don't assume every problem needs more stability.
Don't assume the compound lift will magically fix everything if you just keep coaching it.
Use everything.
Just use it intelligently.
Sometimes the answer is to zoom out and look at the whole person.
Sometimes the answer is to zoom in on one joint.
Sometimes five minutes spent addressing one specific limitation changes the entire movement.
That isn't ignoring the fact that the body works as a system.
It's understanding the system well enough to know when one piece needs attention.
So the next time you hear someone say...
"Movement doesn't happen in isolation."
Just nod your head.
Smile.
Of course it doesn't.
But that doesn't mean we can't isolate something when it needs to be addressed.
