Are Your Glutes Weak or Just Inhibited?

Are Your Glutes Actually Weak? Or Just Inhibited by Your Low Back? | Your Wellness Nerd

Key insights: 60-second read

  • Your glutes may not be weak - they may be inhibited - poor low back function can create a neural block that prevents your glutes from firing properly.
  • Immediate improvement is possible - by addressing specific joint restrictions in the lower back, some people experience an instant increase in gluteal strength.
  • Strengthening is still important - but removing inhibition means you're strengthening from a more honest baseline.
  • Local + telehealth support available - personalised physio assessment in Port Macquarie or via video consult.

Weak glutes are a common diagnosis associated with poor sports performance, pain, and injury. Once identified, the logical next step is to work hard on strengthening those gluteal muscles. Through conventional progressive resistance programs, we usually see improvement over a number of weeks.

But what if your glutes aren't actually weak in the first place? What if, instead, they're inhibited by less-than-optimal low back function?

Clinically, this is something I see regularly with my patients. By focusing on a specific area of the low back, we can often re-ignite the area and observe immediate strength improvements. This isn't about replacing glute strengthening. It's about asking whether we're addressing the first step in a dysfunctional process, or simply the last and most obvious one.

Video: The Low Back & Glute Inhibition Connection

Rehab facilities and gyms across the globe rightfully place huge value on gluteal strength. Those glutes are foundational for good hip, knee, pelvis, and low back function. But if the weakness is a consequence of something else, all the bridging and clamshells in the world will only take you so far.

The Low Back-Glute Connection

The nerves that supply the gluteal muscles originate from the lower lumbar and upper sacral spine - specifically nerve roots L4, L5, S1, and S2. These nerve roots exit between the vertebrae and must pass through the surrounding joints and soft tissues before they reach the glutes.

When the joints of the lower back become stiff, particularly in the thoracolumbar junction or upper lumbar segments, it can affect tissue supplied by these nerves. The glutes may still fire, but they don't fire as forcefully or as efficiently as they could. And when you test strength in this inhibited state, it's easy to conclude the muscle is weak. But what if it's simply not receiving the full message?

Foam Roller Back Joint Mobility

The exercise demonstrated in the video targets the specific segments of the lower back that appear most influential in glute inhibition. Using a foam roller, we're not trying to 'massage' muscle tissue. Instead, we're introducing gentle, localised movement into stiff spinal joints - particularly the posterior-anterior glide of the vertebrae.

This is a mobilisation technique, not a massage technique. The goal is to restore normal play to joints that have become stiff, thereby improving the environment for the nerve roots that pass through or near them. When done appropriately, many people report an immediate change in how their glutes feel during subsequent strength testing.

Gluteal Strength Re-Test

The most compelling part of this approach is the immediate feedback. After performing the mobilisation technique, re-testing glute strength - whether through manual muscle testing, bridging, or clamshells - often reveals an measurable improvement. Not a cure, and not permanent without ongoing work. But enough to demonstrate that something real has shifted.

This instant change is what suggests inhibition, not true weakness, was the primary issue. And it opens up a different conversation about how we approach gluteal dysfunction in both rehabilitation and performance settings.

Helpful equipment

  • Foam Roller - to mobilise those stiff lower back joints
  • Lacrosse Ball - for more targeted joint mobilisation
  • Booty Bands - to strengthen that booty once inhibition is addressed

It is with genuine excitement that I share these findings. This approach has the potential to change how we think about gluteal weakness - not as a replacement for strengthening, but as a precursor to it.

Frequently Asked Questions

1. How do I know if my glutes are weak or inhibited?

A thorough assessment by a physiotherapist is the most reliable method. However, if you have a history of low back stiffness, if your glutes feel 'asleep' or difficult to activate, or if you see an immediate improvement after spinal mobilisation, inhibition may be a factor.

2. Can I still do glute strengthening exercises if my back is stiff?

Yes, but you may not be getting the full benefit. If neural inhibition is present, you're effectively trying to strengthen a muscle that isn't receiving a full signal. Addressing any back dysfunction may allow you to strengthen from a more honest baseline.

3. How often should I do the foam roller exercise?

This depends on your individual response. For some, once a day is helpful. For others, a few times per week is sufficient. The key is consistency over intensity - small, frequent doses of movement tend to work better than aggressive, infrequent sessions.

One profound insight

"Weak glutes are often a symptom, not a diagnosis. Before committing to weeks of strengthening, consider whether low back stiffness is muting the signal to your glutes. Remove the handbrake."

Living With Persistent Gluteal Weakness or Low Back Stiffness?

If your glutes feel unresponsive, or you've been strengthening with limited results, a broader approach may help. Learn more about our physiotherapy services in Port Macquarie.
