How to Build Muscle: Why Your Muscle Activation May Be Holding Back Your Gains
If you’re training hard but one muscle never seems to do its share of the work, adding more weight isn’t always the answer.
You might be squatting regularly, eating enough protein and getting plenty of training volume, yet your glutes still feel like passengers while your quads do everything. Or your back work turns into an arm workout. Or one side consistently feels stronger than the other.
That’s where how to build muscle becomes more than a question of sets, reps and calories.
Your nervous system has a big say in which muscles contribute to a movement. If a muscle isn’t contributing well, other muscles can pick up the slack.
At Pursuit Physiotherapy, this is one area where Neubie therapy Springwood can be useful, particularly for active people who are trying to improve muscle recruitment, manage recurring joint pain or get more from their training.
Building muscle isn't just about lifting heavier
Hypertrophy (increasing muscle size) requires enough training stimulus over time.
That part isn't complicated.
But there's a difference between putting a muscle under load and actually getting that muscle to contribute effectively to the movement.
Take a squat.
You might intend to train your glutes, but your quads could be doing most of the work. Your body doesn't particularly care which muscle gets the credit. It just wants to complete the movement.
If your glutes aren't contributing properly, another muscle will often step in.
This can become more obvious when you increase the load.
The weight goes up. Your technique changes. The stronger muscles take over.
That's not necessarily a lack of effort.
It can be a muscle activation problem.
Your brain and muscles are constantly talking
Every muscle contraction starts with a signal from your nervous system.
Your brain sends an outgoing motor signal through the nervous system to tell a muscle to contract. At the same time, sensory information is coming back from your muscles and joints, giving your brain information about position, tension and movement.
This two-way communication is part of how you control a lift.
You can think of it like a conversation.
The brain says, "Contract now."
The muscle and surrounding tissues respond with information about what's happening.
Then the brain adjusts the movement.
When that communication isn't working efficiently, you may find yourself relying on other muscles without even realising it.
Why can one muscle keep getting left behind?
There are plenty of reasons.
Previous injuries, pain, fatigue, changes in technique and simply doing the same movement pattern for years can all affect how you recruit muscles.
Your body also has a habit of finding the easiest way to complete a task.
That can create compensation.
For example, during a squat, the quads may dominate while the glutes contribute less than expected. During a pressing movement, one side may take over because it's stronger or more comfortable.
You can still move the weight.
That's the tricky part.
Nothing necessarily looks obviously wrong.
Common signs include:
One muscle rarely feels like it's working
One side consistently feels stronger
You struggle to "find" a target muscle
Other muscles fatigue first
Your technique changes as the set gets harder
You repeatedly develop joint pain lifting Springwood despite changing your programming
These aren't proof that you have an activation problem. They're reasons to have the movement assessed rather than simply adding more volume.
Where does the Neubie fit?
The Neubie is an electrical stimulation device used alongside active movement and hands-on treatment.
At Pursuit Physiotherapy, a clinician can use the device while assessing how different areas respond to stimulation and movement.
The interesting part isn't simply making a muscle contract.
It's seeing how your body responds.
Some areas may respond strongly. Others may barely react. Certain muscles may feel like they're switching on easily, while another area appears much harder to engage.
That information can help guide the treatment and exercise selection.
This is where Neufit sports physio can be particularly relevant for people who aren't just looking for temporary muscle relief, but want to improve how they move during training.
What about the "scan"?
The Neubie system can be used with a scanning approach to identify areas that respond differently during assessment.
Think of it as looking for differences rather than assuming the problem is where you feel it.
You might have a sore knee, for example, but the knee isn't necessarily the only thing worth examining.
Your hip strength, ankle mobility, muscle recruitment and lifting technique may all be contributing.
The same applies to bodybuilding.
If one muscle isn't growing as expected, repeatedly hammering that muscle with more exercises may not solve the underlying problem.
Sometimes the better question is:
Why isn't this muscle contributing properly in the first place?
Getting the target muscle working before you lift
This is where an active Neubie session can fit into a training plan.
Rather than using stimulation passively while you lie on a table, the treatment can be combined with controlled movements.
The goal is to prepare the nervous system and target muscles before loading them heavily.
For someone working on glute recruitment, for example, that might involve specific activation work before squatting or hip-dominant exercises.
For a bodybuilder, it could be used before a session where getting a particular muscle to contribute properly is the main priority.
The aim isn't to create an artificial pump and call the job done.
The real test is what happens when you lift.
More muscle activation doesn't automatically mean more muscle
This distinction matters.
You don't build muscle simply because you can feel a muscle contracting.
Hypertrophy still comes down to progressive resistance training, sufficient volume, recovery, nutrition and consistency.
Neubie therapy isn't a replacement for those things.
It may be useful when movement quality or muscle recruitment is getting in the way of your training.
That's particularly relevant if you've been training around an injury or constantly changing exercises because something doesn't feel right.
How this can fit into bodybuilding rehab
A good bodybuilding rehab Springwood program shouldn't force you to choose between rehabilitation and training.
There may be a period where certain exercises need to be modified.
Maybe your usual squat isn't appropriate right now. Maybe pressing causes joint irritation. Maybe a particular range of motion keeps aggravating an old problem.
That doesn't automatically mean stopping the gym.
Instead, your physiotherapist can look at:
Which movements currently aggravate symptoms
Which muscles are contributing
Where compensation is occurring
How your technique changes under fatigue
What exercises you can still train safely
How to progressively return to heavier loading
That's a much more useful approach than simply being told to rest until everything feels perfect.
When should you see a physiotherapist?
If you're asking how to build muscle because your training has stalled, the problem may be your program.
But if you're consistently dealing with pain, obvious strength differences or a muscle that refuses to contribute, it's worth looking beyond your exercise selection.
A physiotherapy assessment can help determine whether you're dealing with a programming issue, movement restriction, pain-related inhibition or a genuine strength deficit.
At Pursuit Physiotherapy in Springwood, Neubie therapy Springwood can be incorporated into an assessment and rehabilitation program where appropriate. The focus remains on getting you moving and training better, rather than relying on the device as a standalone treatment.
If joint pain lifting Springwood is repeatedly interrupting your training, or you're struggling to get a target muscle working properly despite months of consistent training, book an assessment with Pursuit Physiotherapy.
Sometimes the answer isn't another exercise.
You may need to figure out why your body keeps choosing the wrong one.
