The Morning Struggle: Moving Past the Stiffness
We need to talk about that moment right when you wake up. You know the one—where your alarm goes off, and for a split second, you feel fine. Then, you try to roll over, and it hits you. It feels like your spine has been replaced by a rusted iron rod overnight. As an autoimmune specialist, I hear this story every single day from patients across the globe, from bustling streets in New York to quiet neighborhoods in Kyoto. The main answer to this struggle lies in specific ankylosing spondylitis exercises for back pain that target inflammation specifically.
If you are reading this, you are likely looking for relief, not a medical textbook lecture. Ankylosing Spondylitis (AS) is tricky because it defies the logic of "normal" back pain. With a regular gym injury, you rest to heal. With AS, rest is often the enemy. The inactivity allows inflammatory cells to settle in your joints, fusing things together like drying cement. It sounds scary, I know. But here is the good news: you have a tool that is more powerful than many pills. That tool is movement.
In my experience treating hundreds of patients, the ones who thrive are the ones who refuse to stay still. They don't run marathons every day; they just move smartly. They understand that "motion is lotion." When you perform the right movements, you are literally pumping distinct fluids into your spinal joints, breaking up that "rust," and telling your immune system to calm down. In this guide, we aren't just going to list exercises; we are going to build a lifestyle that keeps you flexible, upright, and smiling.

1. Why "Motion is Lotion" for AS
Let's break down the "why" before we get to the "how." Many of my patients ask me, "Doctor, if my back is inflamed, won't moving make it worse?" It is a valid fear. Pain usually signals us to stop. But with Ankylosing Spondylitis, the pain is coming from enthesitis—inflammation where tendons and ligaments attach to the bone. When you stay still, this inflammation pools, leading to stiffness and, eventually, new bone formation (fusion).
Think of your spine like a bicycle chain. If you leave a bike out in the rain and never ride it, the chain rusts and seizes up. But if you oil it and ride it daily, it stays loose. Exercise acts as that oil. It increases blood flow, which flushes out inflammatory chemicals. It also signals your body to maintain the range of motion in your joints. If you don't use that range of motion, your body assumes you don't need it and starts to calcify the joint to "stabilize" it.
However, this doesn't mean you should go lift heavy weights immediately. The goal here is mobility, not just muscle mass. We want to keep the space between your vertebrae open and flexible. Consistent, gentle movement beats intense, sporadic workouts every time. You are playing the long game here.
2. Safety First: Listening to Your Body
Before you jump onto a yoga mat, we need to set some ground rules. I have seen too many enthusiastic patients hurt themselves because they ignored their body's warning signals. There is a difference between "good pain" (the feeling of a muscle working or stretching) and "bad pain" (sharp, shooting sensations). With AS, you might have days where your fatigue is overwhelming. That is okay.
The golden rule in my clinic is "Respect the Flare." If you are in an active flare-up—where your joints are hot, swollen, or you have a fever—you need to dial it back. High-impact activities like running on concrete or heavy deadlifts can aggravate inflammation during a flare. Instead, switch to water-based activities or very gentle range-of-motion exercises. Never force a joint past a point where it feels stuck.
Also, always consult your rheumatologist or a physical therapist before starting a new routine. They know your specific X-rays. If you have any fusion already present in your neck or lower back, certain twisting motions might be risky. We want to mobilize the spine, not stress a fused area. Safety isn't about fear; it's about longevity.
3. The Morning Rescue: Bed Stretches
The battle against AS is often won or lost in the first 20 minutes of the morning. Morning stiffness is the hallmark of this disease. Why? Because you've been inactive for 8 hours. I always tell my patients: do not jump out of bed immediately. Use your mattress as your first gym mat.
Start with a simple knee-to-chest stretch. Lying on your back, gently pull one knee toward your chest while keeping the other leg flat. Hold it for 20 seconds. This gently opens up the lower back and the sacroiliac (SI) joints, which are often the primary source of pain. Alternate legs. It’s a safe, low-risk move that tells your lower back, "Okay, we are waking up now."
Next, try a pelvic tilt. Lie on your back with knees bent and feet flat on the bed. Tighten your stomach muscles and push the small of your back into the mattress. You aren't lifting your hips high; you are just rocking your pelvis. This engages your core and stretches the lumbar spine. Doing 10 of these before your feet even touch the floor can reduce that "robotic" feeling when you finally stand up.
4. The Cat-Cow: Your Spine's Best Friend
If you only do one exercise for the rest of your life, make it the Cat-Cow. This comes from yoga, but it is a staple in rheumatology clinics worldwide. It moves the spine through flexion (bending forward) and extension (bending backward), covering the full range of motion that AS tries to steal from you.
Get on your hands and knees on a soft mat (protect those knees!). Make sure your hands are under your shoulders and knees under your hips. Inhale deeply, drop your belly towards the floor, and look up at the ceiling. This is the "Cow." You should feel a stretch in your abs and a gentle arch in your back. Then, exhale slowly, tuck your chin to your chest, and arch your back up like a scared Halloween cat. This is the "Cat."
The magic here is in the rhythm. Don't hold the poses for too long; flow between them with your breath. Inhale up, exhale down. I recommend doing this for 2 minutes straight. It lubricates the facet joints of the spine. Many of my patients report that this single exercise helps them turn their heads easier while driving and reduces that nagging mid-back pain.
5. Posture Power: The Chin Tuck
AS loves to pull you forward. Over time, the disease can cause a kyphosis, or a "hunchback" posture, where the head juts forward and the shoulders round. This is often called the "skier’s posture." To fight this, we need to strengthen the deep neck flexors and remind your head where it belongs—right on top of your shoulders, not in front of them.
The Chin Tuck is deceptively simple but hard to do right. Sit up straight. Look directly ahead. Now, without tilting your head up or down, pull your chin straight back as if you are trying to make a "double chin." It’s not a flattering look, I know! But it is incredibly effective. You should feel a stretch at the base of your skull and the top of your neck.
Hold this "double chin" position for 5 seconds, then release. Repeat it 10 times. You can do this anywhere—at your desk, in the car at a red light, or watching TV. It counters the weight of gravity pulling your head forward. Keeping your neck aligned is crucial because once the neck fuses in a forward position, it becomes very difficult to see straight ahead, impacting your balance and quality of life.
6. Wall Sits: Strength Without Strain
Leg strength is your secret weapon. When your back is painful, you start relying more on your legs to get up from chairs, to climb stairs, and to lift things. If your legs are weak, you strain your back more. It’s a vicious cycle. But, doing heavy squats with a barbell on your back? That might be too much compression for an inflamed spine.
Enter the Wall Sit. This is an isometric exercise, meaning you build strength without moving the joints constantly. Find a sturdy wall. Lean your back flat against it and slide down until your knees are bent at roughly a 45 to 90-degree angle (go only as low as is comfortable). Your feet should be shoulder-width apart.
Hold this position. You will feel your quads (thigh muscles) firing up. Keep your head and spine pressed gently against the wall. This teaches you to maintain a straight spine while your legs do the heavy lifting. Start with holding it for 20 seconds and work your way up to a minute. It’s safe, effective, and requires zero equipment.
7. Opening Up: The Corner Chest Stretch
As I mentioned earlier, AS tends to curl the body inward. Our modern lifestyle of hunching over smartphones and laptops only makes this worse. We need to open the chest cavity. If your chest muscles (pectorals) are tight, they pull your shoulders forward, increasing the curve in your upper back.
Find an empty corner of a room. Stand facing the corner. Raise your arms to shoulder height and place your forearms on the walls, one on each side, with elbows bent at 90 degrees. Gently lean your body weight forward into the corner until you feel a nice, deep stretch across the front of your chest. Do not let your lower back sway or arch excessively; keep your core tight.
Hold this for 30 seconds. Breathe deeply. Deep breathing is actually part of the exercise here. AS can sometimes stiffen the ribs (costochondritis), making it hard to take full breaths. By stretching the chest and breathing deeply, you are working on your rib cage mobility, ensuring your lungs have plenty of room to expand.
8. Why Swimming is the Gold Standard
If there is an Olympics for AS exercises, swimming takes the gold medal every time. I cannot recommend this enough. When you are in the water, gravity is essentially "turned off." The buoyancy of the water supports your weight, taking the pressure off your inflamed spinal joints, knees, and hips.
Swimming allows you to move your limbs through a full range of motion without impact. The breaststroke is particularly good for opening the hips and extending the upper back, though you must be careful not to arch your neck too much. The backstroke is arguably the best because it forces you to lie flat, countering the forward hunch, and opens up the chest and shoulders as you rotate your arms.
Even if you aren't a strong swimmer, just walking in the pool or doing water aerobics is fantastic. The water provides natural resistance, which builds muscle strength without the jarring impact of land exercises. Plus, the hydrostatic pressure of water can actually help reduce swelling in the joints. It’s soothing, it’s effective, and it’s safe.
9. Walking: Simple but Effective
Sometimes the best solutions are the simplest. Walking is highly underrated. It is a weight-bearing exercise, which is crucial for maintaining bone density (osteoporosis is a risk with AS). But more importantly, the act of walking engages the pelvic muscles and gently rotates the spine in a natural rhythm.
However, you need to walk with intention. No shuffling! When you walk, imagine a string pulling the top of your head toward the sky. Swing your arms gently. This arm swing is important—it creates a gentle rotation in the upper spine, keeping it mobile. Wear shoes with excellent shock absorption. Walking on concrete with bad shoes will send shockwaves up to your SI joints.
If you find long walks painful, try "interval walking." Walk for 10 minutes, then sit and rest for 5. Then walk another 10. Cumulative movement is just as good as continuous movement when it comes to reducing inflammation. Listen to a podcast or an audiobook, and let your body find its natural rhythm.
10. Yoga vs. Pilates: Which Wins?
I get asked this constantly: "Doc, should I do Yoga or Pilates?" The answer is: both, but for different reasons. In my experience, a combination is magic, but if you have to choose, you need to know what you are getting.
Yoga is fantastic for flexibility, breathwork, and stress reduction. Stress triggers flares, so the mental aspect of yoga is medicinal. Styles like Hatha or Yin yoga are great. Avoid "Power Yoga" or "Hot Yoga" initially until you know your limits, as they can be too intense. The focus in yoga on extension (backward bending) is perfect for AS.
Pilates, on the other hand, is all about the "powerhouse"—your core. AS patients often have weak cores because pain changes how they move. Pilates strengthens the deep abdominal muscles and the muscles along the spine that support your posture. It is often done lying down, which supports the spine. If I had to pick one for stability, it’s Pilates. If I pick one for mobility, it’s Yoga.
11. Trusted Resources & Real Videos
The internet is full of bad advice. As a specialist, I want to point you toward the resources that we doctors actually trust. These organizations and creators understand the specific mechanics of Ankylosing Spondylitis.
- Spondylitis Association of America (SAA): They are the authority. Their website has a treasure trove of exercise guides.
Search for: "SAA Exercise Corner" - NASS (National Axial Spondyloarthritis Society): A UK-based charity that has an incredible "Back to Action" exercise program. They offer downloadable PDFs and apps.
Search for: "NASS Back to Action app" - Yoga for AS (YouTube): There are specific instructors who have AS themselves. Look for channels like "Yoga for AS" where the instructor modifies poses specifically for fused or stiff spines.
When looking for a video, always check the credentials. A generic fitness influencer might tell you to do deep backbends that are dangerous for someone with AS. Stick to content created by physiotherapists or specialized organizations.
12. Lifestyle Habits That Boost Exercise
You can do all the exercises in the world, but if the rest of your lifestyle promotes inflammation, you are swimming upstream. Exercise doesn't happen in a vacuum. To get the most out of your movement, you need to support your body with what I call the "AS Toolkit."
First, look at your sleep setup. A mattress that is too soft will let your spine sag, causing morning pain. A medium-firm mattress is usually best. Second, look at your diet. Many of my patients find relief by reducing processed sugars and starches, which can feed inflammation. It’s not about a strict diet, but about eating whole foods that fuel your recovery.
Finally, stop smoking. If you smoke, please stop. Smoking is significantly linked to faster spinal fusion in AS patients. It constricts blood vessels and reduces the effectiveness of the very exercises we just discussed. Combining a smoke-free life with these exercises is the ultimate way to tell your AS that it is not in charge—you are.
Conclusion & Next Steps
Living with Ankylosing Spondylitis is a journey that no one chooses, but it is one you can navigate with strength. We have covered a lot today, from the simple bed stretches that greet your morning to the core-strengthening power of wall sits and Pilates. Remember, the goal isn't to be perfect. The goal is to be persistent.
In my years of practice, the patients who maintain the best quality of life aren't necessarily the ones with the mildest cases on X-ray. They are the ones who show up for themselves every day. They treat their exercise routine like brushing their teeth—non-negotiable, essential hygiene for their spine. You have the power to change the trajectory of this disease. By keeping your spine mobile, correcting your posture, and strengthening the muscles that support you, you are actively fighting back against fusion.
Start small. Pick just three exercises from this list—maybe the Cat-Cow, the Chin Tuck, and a daily walk. Do them for two weeks. I promise you will feel a difference. You will feel less like a "tin man" and more like yourself.

Frequently Asked Questions (FAQ)
1. Can exercise stop my spine from fusing?
While exercise cannot guarantee that fusion will never happen (as genetics play a role), it is the best proven method to slow down the process and ensure that if fusion occurs, it happens in an upright, functional posture rather than a hunched one.
2. How often should I exercise with Ankylosing Spondylitis?
Ideally, you should do range-of-motion exercises (like stretching) every single day. Cardiovascular and strengthening exercises can be done 3 to 4 times a week. Consistency beats intensity.
3. Is running bad for Ankylosing Spondylitis?
Not necessarily, but it depends on your disease severity. If you have significant fusion or hip involvement, the impact of running might be painful. Walking or swimming are generally safer alternatives.
4. What should I do if exercise hurts?
Stop immediately if the pain is sharp. If it is a dull ache from muscle work, that is usually okay. If you are in a flare-up, switch to very gentle stretching or aquatic therapy.
5. Can I lift weights with AS?
Yes, strengthening muscles supports the joints. However, focus on lighter weights and higher repetitions. Avoid heavy overhead lifting that compresses the spine unless cleared by a pro.
6. Why is my back pain worse in the morning?
Inflammatory back pain worsens with rest because inflammatory chemicals accumulate in the joint fluid while you are inactive. Movement helps flush these out, which is why you feel better after moving.
7. Does posture really matter that much?
Yes. If your spine fuses, it will fuse in the position you spend the most time in. Maintaining good posture ensures that you retain the ability to look forward and maintain balance.
8. Are there specific shoes for AS?
Look for shoes with maximum shock absorption and good arch support. Brands that cater to running or walking (like Brooks or Asics) are often recommended to reduce impact on the spine.
9. Can hot yoga help my AS?
Heat helps loosen stiff muscles, so many AS patients love it. However, be careful not to overstretch just because the heat makes you feel flexible, as you could injure the connective tissue.
