Why You Can’t Feel Certain Muscles (And Why That Matters)

The Frustration Most Women Don’t Talk About
One of the most common things I hear as a Personal Trainer is:
“I’m doing the exercise… but I don’t feel anything where I’m supposed to.”
Or:
“I feel everything except what I’m trying to work.”
This is especially common with:

• Glutes
• Core
• Upper back

And it can be incredibly frustrating.
Because you’re showing up.
You’re doing the work.
But your body doesn’t seem to be responding the way it should.

It’s Not a Strength Problem
Most people assume this is a strength issue.
They think:
👉 “I just need to get stronger”
But that’s not actually the problem.
In many cases, the muscle isn’t weak.
It’s just not being recruited effectively.
Your body is very good at completing movement.
But it doesn’t always use the right muscles to do it. And there is a reason for it.

What I See With My Training Clients
With many of my more mature clients, this shows up very clearly—especially in the upper back.
They often struggle to isolate those muscles.
Instead, they compensate with their arms.
And the challenge is—over time, arm strength begins to decline.
So now the body is relying on something that is no longer as dependable, while the muscles that should be supporting posture and movement haven’t been developed.
This is where things start to feel harder than they should.

Your Body Will Always Find a Way
If a muscle isn’t engaging properly, your body will compensate.
It will shift the workload to:

• Stronger muscles
• More dominant patterns
• Areas that are already overused

For example:

• Hamstrings taking over for glutes
• Lower back compensating for core
• Arms doing the work instead of the upper back

The movement still happens.
But the result is different.

Why This Matters Beyond Appearance
This isn’t just about how your body looks.
It’s about how your body functions over time.
Your legs are your support system.
There is strong evidence showing a direct relationship between leg strength and longevity.
When mobility begins to decline, so does your ability to:

• Move freely
• Engage with your environment
• Stay physically independent

And that affects more than the body.
It changes how you interact with the world.
This isn’t just about advanced age.
It’s about being 55 and not being able to comfortably hike a trail, travel fully, or enjoy the experiences you’ve worked for.
That’s a loss that has nothing to do with aesthetics—and everything to do with quality of life.

What Happens When Activation Clicks
The good news is—this can change.
I’ve had clients joke with me that I’ve helped them discover muscles they didn’t even know they had.
And it’s true.
Sometimes it shows up as:

• Mild soreness in a place they’ve never felt before
• A completely different sensation in a familiar movement
• A realization that they weren’t working what they thought they were

The movement might look the same from the outside.
But internally, everything is different.
That’s where change begins.

Familiar Movement vs. Effective Movement
There’s value in familiar exercises.
But familiar doesn’t always mean effective.
To truly change your body—and how it functions—you have to introduce new patterns.
Unfamiliar ones.
Movements that challenge coordination, balance, and muscle recruitment in new ways.
And as those become familiar… you evolve again.
This is one of the reasons athletic individuals often “look different.”
Not because of any one exercise--
But because they’ve developed a wide range of movement patterns and neuromuscular control.

You Can’t Skip the Foundation
That said, you can’t jump straight into advanced or unfamiliar training without preparation.
There are layers to the body:

• Muscle
• Connective tissue
• Joint stability

These all need to be conditioned progressively.
This is why I often discourage deconditioned individuals from jumping into:

• High-intensity group programs
• Competitive-style workouts
• Challenge-based training

Not because those are bad--
But because without a foundation, the body will compensate.
And in those environments, it’s human nature to:

• Push too hard
• Match others
• Ignore limitations

Which often leads to:

• Injury
• Setbacks
• Or repetitive movement patterns that create long-term issues

Slow Is the Way to Fast
Real progress is built strategically.
Not rushed.
When you train with intention:

• The right muscles engage
• The body adapts properly
• Progress becomes sustainable

This doesn’t mean you need a personal trainer forever.
Or that you need to become an expert in anatomy.
Even small shifts can make a difference.

Expanding How You Move
One of the simplest ways to begin is to step outside of your usual patterns. Have fun with it. Don't judge yourself. Show other women how you are not afraid to change to become a better you. You have a very supportive community!
If you’ve been doing the same type of exercise for years:

• Try something different
• Move in new ways

For example:

• Zumba instead of yoga
• Tennis instead of jogging
• Hiking instead of walking the dog
• Basketball hoops instead of pickleball

Or better yet—rotate through different styles in phases.
This develops:

• Balance
• Coordination
• Strength
• Flexibility
• Reaction time

And reduces the likelihood of building compensations that lead to injury.

Connection Is What Changes Everything
The more you move—and the more intentionally you move—the more awareness you build.
This is how the body learns.
This is how muscles begin to engage properly.
This is how real change happens.
Not just through repetition--
But through connection.

A Different Way to Approach Training
Instead of asking:
“How many reps did I do?”
A better question becomes:
👉 “Did I feel what I was supposed to feel?”
That shift changes everything.
Because it moves you from:

• Completing workouts

To:

• Training your body with purpose
