Back or Knee Pain? Uh-Oh, You May Have ‘Dead Butt Syndrome’

Nov. 13, 2025 – You won’t find any support groups for dead butt syndrome, aka gluteal amnesia, sleepy glutes, flabby butt, longback, or, for King of the Hill fans, diminished gluteal syndrome.

“They all mean sort of the same thing: weak gluteal muscles,” said Dean Somerset, a clinical exercise physiologist based in Edmonton, Alberta, Canada, and co-author of Rock Solid Resilience.

If you guessed that small, weak, and poorly functioning glutes are often the result of too much sitting and too little exercise, you wouldn’t be wrong, according to Somerset.

Meanwhile, Los Angeles-based physical therapist Chad Waterbury, DPT, has seen it in healthy, fit, active clients, including a few professional athletes. “When we do exercises like squats, deadlifts, lunges, it’s very easy for other muscles to do the work you want the glutes to do,” Waterbury said

In both populations, the glutes stop doing what they should, and that can lead to serious problems up and down the movement chain.

If misfiring glutes force the lower-back muscles to take on loads they’re not meant to handle, the result can be years of back pain. And if the glutes fail to perform their stabilizing role in exercise and sports, you could be looking at chronically sore knees, or perhaps even an ACL injury.

That means the Venn diagram of dead butt sufferers includes people who sit a lot, active people, those with back pain, and those with knee pain. All those people, all that overlap, all those butts.

Is your butt among them?

Putting a Name to the Pain

Stuart McGill, PhD, coined the term “gluteal amnesia” to describe what happens when pain causes people to change how they move.

“In people with longer-term pain, the pattern of nerve pulses distributed to the muscles can become corrupted,” he explained. “The pain kicks off an inhibition pathway, so the brain finds a different way to do the same basic thing.”

That, in turn, changes the way muscles like the hamstrings contribute to the movement.

“But even when the pain has gone away, the brain often remembers the painful pattern,” McGill said. Which means it also forgets how to use the muscles appropriately and efficiently.

McGill, a distinguished professor emeritus at the University of Waterloo and author of Back Mechanic, showed how the process works in a 2013 study. In that paper, he and his co-authors used “gluteal amnesia” and “gluteal inhibition” interchangeably.

The latter term is probably more appropriate, given that some people hear the former and think it implies gluteal dementia, as if the misplaced movement patterns can never be restored.

Fortunately for the gluteally deficient among us, they can. Just not in the way most of us would assume.

Hips, Femur, Knees, and Woes

While McGill was teasing out the connection between gluteal amnesia and back pain, Christopher Powers, PT, PhD, was looking at how abnormal glute activation patterns could lead to knee problems.

“The gluteal muscles control the femur,” he explained. “The femur’s half the knee joint. So by definition, the gluteal muscles control half the knee.”

Powers is associate chair of the Division of Biokinesiology and Physical Therapy at the University of Southern California, where he studies the root causes of the lower-body injuries. And he addresses a lot of them with the athletes and patients he sees at the Movement Performance Institute in Los Angeles, which he founded and owns.

His research has shown that a key function of the gluteal muscles is to prevent the femur from rolling inward during sports, exercise, or everyday physical activities.

“Once you stop using the muscle, the brain kind of forgets about it,” Powers said. “You lose the neural connectivity.”

And if the brain forgets how to stabilize the femur, just about anything you do, from walking to landing after a jump, will put stress on your knee joints.

How to Know if Your Butt is Dead or Dying

Remember, given that sedentary and active people have this issue, aside from chronic knee or back pain, you may not be able to tell if your glutes are firing properly or improperly.

Waterbury recommends this self-test: the single-leg glute bridge.

Lie on your back with one leg lifted out straight and the other leg bent at a 45-degree angle with the foot flat on the floor. Your thighs should be parallel. Raise your butt so your thighs and torso form a straight line.

Hold that position for 20 seconds (or as long as you can up to 20), while paying close attention to which muscles you feel are working the hardest. Lower your hips and repeat with the other leg.

If you felt the strongest contraction in your hamstrings or lower back, instead of your glutes, you need to improve your gluteal activation. Also, muscle imbalances are common, so it’s also not unusual for you to feel weaker in one glute or the other.

Two of Powers’s studies offer encouraging news for those whose glutes have lost their way.

The first, published in 2016, found that a week of glute-activation exercises increased neural drive to the muscles.

A follow-up, published in 2022, found that the same exercise protocol made the muscles more able to stabilize the femur.

So let’s take a look at the program.

Wake Up, Dead Butt

Powers’s program includes just three exercises, all of which may look familiar: clamshell, side-lying hip abduction, and fire hydrant.

Even if you haven’t used the exercises in your own routines, you’ve probably seen other people doing variations of them.

Here’s the catch: To do the program correctly, you have to forget what you’ve done or seen.

Instead of doing sets and reps, you’ll hold each position for up to a minute at a time. And you’ll need to do the program almost every day.

“When you do reps – up and down, up and down – the focus tends to be on the movement,” Powers said. Isometric holds like these require something else: intense concentration on squeezing the muscle in one continuous position.

That extended muscle activation allows the brain to reopen its channels of communication. If you follow the isometric holds with exercises that use the glutes, like squats or step-ups, you reinforce those neural signals.

To get the most out of the exercises, you’ll want to use a miniband positioned around your thighs, just above your knees. When you can hold a position for a full minute, use a more challenging band the next time.

Here’s a closer look at each exercise.

Clamshell

Lie on your side with your legs together and your hips and knees bent 45 degrees.

Lift your top knee straight up while keeping your feet in contact with each other.

Feel the squeeze in your glutes and hold for up to a minute. Switch sides and repeat.

Side-Lying Hip Abduction

Lie on your side with your top leg straight and bottom leg bent at the knee about 45 degrees.

Lift your top leg up and slightly back.

Feel the squeeze in your glutes and hold for up to a minute. Switch sides and repeat.

Fire Hydrant

To Powers, the fire hydrant is the best of the activation exercises. “If I were to pick one, I’d take it over the other two,” he said.

But it’s also the trickiest one to get right, since you’re asking your glutes to perform three functions, as you’ll see:

Kneel on all fours with your hips parallel to the floor and your hands shoulder-width apart.

Without shifting your hips, lift one leg up (hip abduction) and back (hip extension). Position your thigh so it’s neither perpendicular to your torso (straight out to the side) nor aligned with it (straight back), but instead about halfway between those two points. (It’s called “fire hydrant” because you’re mimicking a dog doing what a dog does to a fire hydrant.)

Now turn your thigh outward (external rotation) until you feel tension in the band.

The goal isn’t to achieve any particular range of motion. It’s to reach a position you can hold while keeping your hips level with the floor.

Hold for up to a minute, switch sides, and repeat.

Restoring Your Seat of Power

People in Powers’s studies did three isometric holds of each exercise, with each leg, twice a day for seven consecutive days.

But Waterbury, who studied under Powers at USC, uses a streamlined version of the program with clients, athletes, and patients.

Start with these exercises:

Clamshell, 30 seconds per side
Side-lying hip abduction, 30 seconds per side
Fire hydrant, 30 seconds per side

Do the exercises six days a week for four weeks, either on their own or as part of a warmup before a workout. “That’s plenty to get the glutes activated,” Waterbury said.

After four weeks, do the exercises three times a week, preferably before a strength workout that includes squats, deadlifts, lunges, or other movements that use your glutes in coordinated action with other lower-body muscles.

You can also do more advanced versions of the exercises, as Waterbury demonstrated in this video.

What matters most, he emphasized, is that you make these isometric holds a permanent part of your fitness routine.

“Too many things we do throughout the day make your glutes want to shut down again,” he said.

Ultimately – and this is pretty good life wisdom – it’s a lot easier to keep your butt alive and well than it is to bring it back from the dead.

How much exercise is enough? A local doctor says you only need 15 minutes a day – WTOP News

How much exercise is enough? A local doctor says you only need 15 minutes a day – WTOP News

Exercise is part of a healthy lifestyle and its benefits are well known and have been for a long time. What is only recently proven by doctors is just how much exercise makes a difference for one’s longevity.

By now, most people understand that exercise is part of a healthy lifestyle; its benefits are well known and have been for a long time. What is only recently proven by doctors is just how much exercise makes a difference for one’s longevity.

For most people who sit at desks or behind the wheel all day, the problem is often finding time to work out. The good news, according to Dr. Julie Chen, an internal medicine and lifestyle medicine doctor at Kaiser Permanente in Gaithersburg, is that a daily exercise routine can be broken down into brief segments.

“The general recommendation is for 150 minutes of moderate activity per week,” Dr. Chen said. “So that is roughly about 30 minutes a day, five days a week. But the important point is it does not have to all be done at once. You can break it up into shorter segments of exercise and still get the same great benefits.”

And those benefits can be tremendous. Chen said that studies have shown going from no exercise a day to only 15 minutes of total exercise a day can “can actually decrease their risk of death, death from all causes, by about 14%.”

“Any movement is actually better than being sedentary,” she said.

Movement can be divided up into short segments throughout the day instead of in one long, strenuous workout and it can still offer the same reductions in the risk of certain diseases.

Now, you might understand there are benefits of exercising for short periods of time, several times per day; but you might be wondering how you can get in the gym several times a day.

Chen advocates for what she calls “exercise snacks” — “small bursts of physical activity that you can get in, two to three minutes at a time throughout the day.”

For example, taking the stairs or doing squats while putting groceries away, walking around the office on a phone call or planking while your dinner is in the microwave. Chen said try to do whatever it takes to get a few minutes of movement in a few times a day.

Chen is also a big fan of fitness apps, including the ones that come built into our smartphones and watches: “Studies have shown that that is really motivating that you can actually track your progress in your app. You can see your trends.”

“Consistency is a really big goal of this effort, and so if you look at your trends over time, that’s going to be a really rewarding aspect of trying to improve your health,” she added.

Beginning an exercise regimen doesn’t need to be complicated or time-consuming. You don’t need to splurge on workout clothes or a gym membership; you just need a few minutes, several times a day, to start reaping the benefits.

Adults hop on viral ‘rebounding’ trend to make exercise fun again — ‘I feel like a kid’

Forget boring home workouts, on-demand HITT classes and cold winter runs.

The latest wellness trend bouncing around TikTok involves a workout you might not even realize you’re doing, and that’s the point. It’s called rebounding. This low-impact exercise involves jumping on a mini fitness trampoline — called a rebounder — to get your heart pumping and support lymphatic drainage.

On Amazon, this best-selling model is currently on sale for just $129. It measures in at just 40 inches, making it ideal for small spaces while still offering room for an adult to jump, squat and jog in place. Users swear it gives them a seriously effective full-body workout, and many remark that it’s “so much fun” to use.

Clinical trials also back the benefits: a 12-week rebounding program for overweight women showed significant improvements in body composition as well as a decrease in diastolic blood pressure.

Ready to jump on the rebounding trend, too? You’d better hop on this Amazon deal fast.

Fitness trainer with 18 years of experience shares why exercise is crucial for kids: ‘Not just about health and fitness’

Exercise is often spoken about in the context of physical fitness – stronger muscles, better stamina and improved overall health. But its value, especially for children, extends far beyond the body. Regular physical activity can quietly shape character, teaching lessons about effort, patience, discipline and resilience that mirror how the real world works. From learning to cope with discomfort to understanding that progress takes time, exercise can become a powerful training ground for life itself.

Chennai-based fitness trainer with 18 years of experience, Raj Ganpath – founder of the Slow Burn Method, co-founder and head coach at Quad Fitness, and author of Simple, Not Easy – is shedding light on why exercise is important for kids, with the benefits going beyond health and fitness. In an Instagram video shared on February 27, he explains how the impact of exercise extends far beyond physical wellness, shaping resilience, discipline and long-term character development.

Embracing discomfort

According to Raj, exercise is one of the healthiest ways to help children learn how to sit with discomfort in a safe, structured and sustainable way. Life inevitably brings challenges and unease – something adults understand well – but many children today are shielded from situations that test their resilience.

He explains, “Exercise is a great way to experience this discomfort in a safe and sustainable manner. Lifting weights, holding a plank, doing cardio, repping till it burns, all of these things are opportunities to embrace discomfort, opportunities to put themselves in a place where they’re not comfortable and learn from it, opportunities to practice physical and mental resilience.”

Learning hardship

The fitness trainer emphasises that hardship is an inevitable part of life, and meaningful success often requires pushing through moments of difficulty. While most adults recognise this truth through lived experience, children may not always have the same exposure to challenge. Raj believes exercise can bridge that gap.

He elaborates, “It will teach them that they need to do hard things if they want to accomplish something. Getting through a very hard workout, setting a goal and achieving it, completing a task. All of these things are not just random chores. These are incredible opportunities – opportunities to experience hardship and build fortitude.”

Delayed gratification

In today’s fast-paced world, the desire for instant gratification is stronger than ever – and children are growing up at the centre of it. With technology, streaming platforms and 10-minute delivery services, almost everything is available at the tap of a screen. As a result, the ability to wait, persist and work steadily towards a long-term goal can easily take a back seat. Exercise, notes Raj, offers a powerful counterbalance.

He explains, “Everyone wants everything right away today. This is true for us adults too, but it is even more true for our kids because this is the only world they know. A world where everything happens right then and right there, whenever they want it, wherever they want it. Exercise will teach them to wait, to be patient, to trust the process, to fail and still keep going, to work towards something larger that they will get much later. This is a very important character building quality and will serve them well for many, many years to come.”

The fitness trainer concludes, “Exercise is not just about health and fitness. It is a simulation of life itself. A ready-made character building tool available to you to help prepare your kids for life, the raw and real life that they’re going to have to deal with no matter what. So make sure they build the habit and make sure they embrace it.”
