Does "Gluteal Amnesia" Actually Exist?
If you've ever been told your gluteal muscles are "switched off" or that you have "gluteal amnesia", you're not alone. It's a term that's become incredibly popular on social media and in the fitness world—but what does it actually mean?
What is gluteal amnesia?
Gluteal amnesia (AKA "dead butt syndrome") is the idea that your gluteal muscles have become "inactive" or "forgotten" how to work, often because of prolonged sitting or poor movement habits. The theory suggests that if your gluteal muscles aren't firing properly, other muscles such as your lower back, hamstrings, or hip flexors have to pick up the slack, increasing your risk of pain or injury.
While this sounds plausible, the reality is a little more nuanced.
Can your gluteal muscles really "switch off"?
Not exactly.
Your brain doesn't simply forget how to activate your gluteal muscles. Unless there is a neurological injury affecting the nerves supplying the muscles, your gluteal muscles remain capable of contracting.
While pain, injury or surgery can temporarily alter how muscles are recruited, this isn't unique to the gluteal muscles. Like many other muscles in the body, their activity can change in response to pain, fatigue or altered movement demands. These changes are generally considered protective and are usually temporary rather than evidence that the muscles have "switched off."
Does sitting all day cause gluteal amnesia?
Despite how often this is claimed online, there is very little evidence that sitting permanently "deactivates" your gluteal muscles.
A common explanation is that prolonged sitting causes the hip flexors to become "tight," which then inhibits the gluteal muscles through a process called reciprocal inhibition. While this theory is widely taught, current evidence doesn't strongly support it. Muscles that feel stiff or tight are not necessarily overactive, and reduced hip flexibility doesn't mean the gluteal muscles have been switched off.
After sitting for long periods, your hips may feel stiff and your muscles may feel less responsive initially. This usually improves once you start moving. It doesn't mean your gluteal muscles have forgotten how to work.
The bigger issue with prolonged sitting is that it reduces overall physical activity rather than specifically causing your gluteal muscles to stop functioning.
The best way to build stronger gluteal muscles
Rather than worrying about whether your gluteal muscles are "awake," focus on making them stronger.
It's also worth remembering that there isn't one "correct" way to move. Two people can squat or deadlift with slightly different movement strategies while both performing safely and effectively. Rather than chasing perfect glute activation, the focus should be on progressively loading the muscles, building strength, and improving function.
Progressive strength training remains the most effective strategy, including performing exercises such as:
- Squats
- Deadlifts
- Hip thrusts
- Romanian deadlifts
- Step-ups
- Split squats
The takeaway
"Gluteal amnesia" is a catchy term, but it oversimplifies how the body works. Your gluteal muscles don't simply stop working because you've been sitting at a desk. While pain or injury can temporarily influence how muscles contribute to movement, this doesn't mean your body is broken or that your glutes need to be "woken up."
For most people, the priority isn't chasing perfect muscle activation—it's staying active, getting stronger, and finding movement that helps you reach your goals. If you're dealing with ongoing pain or difficulty exercising, a physiotherapist can help identify contributing factors and develop a program that's tailored to you, rather than relying on simplified explanations or internet myths.
