Can you remember the last time you moved without thinking about your back first? For many of my patients with Ankylosing Spondylitis (AS), that memory is fuzzy. I recall one patient, Mark, who told me he missed the simple act of turning his head to check a blind spot while driving. He’d developed a kind of "robot posture"—everything was a deliberate, sometimes painful, calculation. If you're searching for ankylosing spondylitis exercises for back pain, you're not just looking for a list of stretches. You're seeking a way back to fluid, spontaneous movement. You want complete practical real informational guidance you can trust, not theoretical advice. This post is exactly that: a safe, actionable plan from my years in the clinic, designed to help you manage stiffness, preserve mobility, and reclaim a sense of control over your body.
The problem with AS is its sneaky nature. Inflammation targets the spine and joints, leading to pain, profound stiffness (especially in the morning), and over time, it can encourage the spine to fuse. This isn't just "bad back pain." It's a systemic condition where your immune system gets confused. The absolute worst thing you can do? Become still. Fear of pain leads to guarding, which leads to less movement, which leads to more stiffness and weakness—a vicious cycle. But the right movement is medicinal. The intent of this guide is to break that cycle with clarity and compassion, offering exercises that are both gentle and profoundly effective. We'll move beyond generic advice to strategies specifically tailored for the unique challenges of AS.

What is Ankylosing Spondylitis, Really?
Let's ditch the textbook definition for a moment. Imagine the ligaments and joints in your spine are like the seams of a well-loved shirt. With AS, your immune system mistakenly thinks those seams need constant "reinforcement." It sends inflammatory cells to these areas, causing swelling and pain. Over years, if this inflammation isn't managed, the body can lay down calcium, turning flexible ligament into solid bone—a process called "bamboo spine" in advanced cases. The primary target is the sacroiliac joints (where your spine meets your pelvis), but it can affect ribs, shoulders, hips, and even eyes.
The pain is often deep, gnawing, and worst after periods of rest. That's why mornings can be brutal. I've had patients describe it as feeling "cast in concrete." It's different from mechanical back pain (like a herniated disc), which often feels better with rest. AS pain typically improves with gentle movement and heat. Understanding this "inflammatory" pattern is your first clue to managing it. You're not dealing with a worn-out spine; you're dealing with an overactive immune response in a very specific area. This knowledge changes everything, especially how you approach exercise.
Practical Takeaway: Listen to your pain's "personality." Does it ease up as you move around during the day? That's a classic AS signature. Use this as a guide—gentle motion is your ally, not your enemy.
Why Exercise is Non-Negotiable for AS
I tell every new patient: "Medication controls the fire of inflammation, but exercise preserves the house—your spine." It's a partnership. Exercise maintains the range of motion in your joints, slowing or preventing fusion. It strengthens the muscles around your spine and pelvis, creating a natural "corset" of support that reduces strain on inflamed joints. It pumps blood to stiff areas, literally washing away inflammatory by-products. Perhaps most importantly, it releases endorphins, your body's natural pain relievers, and fights the fatigue and low mood that often accompany chronic conditions.
In my experience, the patients who thrive are the ones who make movement a daily habit, like brushing their teeth. They don't necessarily do high-intensity workouts; they do consistent, mindful movements. A study in the Annals of the Rheumatic Diseases consistently shows that regular exercise improves function, pain, and overall well-being in AS more than medication alone. Think of it not as an optional "workout," but as a critical part of your treatment prescription—one where you are in complete control.
Practical Takeaway: Reframe "exercise" as "movement medicine." Your goal today isn't to burn calories, but to oil your joints and send a signal to your body that these spaces need to remain open and flexible.
The Golden Rules: Exercising Safely with AS
Before we dive into the exercises, let's set ground rules. Safety is paramount, because pushing through the wrong kind of pain can cause setbacks. Rule 1: Distinguish between "good" and "bad" pain. A mild stretch or muscular burn is "good." Sharp, shooting, or joint-pinching pain is "bad." Always stay in the "good" zone. Rule 2: Consistency over intensity. Five minutes daily is worth more than an hour once a week. Rule 3: Warm up with heat. A warm shower or heating pad on your lower back for 10-15 minutes before you start can make a world of difference, especially in the morning. Rule 4: Move slowly and with control. No bouncing or jerking. Your movements should be like slow, mindful tai chi.
It's also wise to consult with a physiotherapist or rheumatologist who understands AS to personalize this plan. What works for one spine may need tweaking for another. And please, if you have any neck instability or severe osteoporosis (which can happen with long-term steroid use), get direct medical clearance first. This advice is for general education, not a replacement for your personal care plan.
Practical Takeaway: Before you try any exercise, apply a heating pad to your stiffest area. Move only to the point of gentle tension, never into sharp pain. If it hurts, stop, reassess, and reduce the range of motion.
Exercise #1 & #2: The Morning Stiffness Tamers
These are done in bed, before you stand up. Lie on your back with knees bent.
#1: Knee-to-Chest Rock
Gently hug one knee toward your chest. Hold for 20-30 seconds, feeling a gentle stretch in your low back and buttock. Slowly rock the knee side-to-side an inch or two, like a pendulum. This mobilizes the sacroiliac joint. Lower it and repeat with the other leg. Do 3-5 per side.
#2: Cat-Cow on Your Back
Keep both feet flat on the bed. Slowly arch your lower back slightly, letting your tailbone tilt down (creating a small space between your back and the bed). Then, reverse: gently press your lower back into the bed, engaging your abs. Move back and forth slowly for 1 minute. This pumps fluid into your spinal discs and warms up the entire spinal column.
I’ve had patients say this 3-minute routine changes their entire day. It tells your stiff spine, "It's time to wake up gently," rather than shocking it with sudden upright movement.
Practical Takeaway: Keep a heat pack by your bedside. Upon waking, apply it for 5 minutes, then perform these two exercises. Only then, roll to your side and use your arms to push up to sitting.
Exercise #3 & #4: Building Your Inner Support System
If your spine is the main character in this story, your core muscles are its loyal support crew. With AS, we’re not talking about six-pack abs. We’re talking about the deep, often-forgotten muscles that act like a natural brace around your lower back and pelvis. Strengthening these is like giving your inflamed joints a protective hug from the inside. One of my patients, a musician named Elena, found that working on her core reduced her reliance on pain medication during long rehearsals. She said it felt like “someone had finally given my spine a reliable chair to sit in.”
#3: The Modified Bridge (The Pelvic Tilt & Hold)
Lie on your back with knees bent, feet flat on the floor hip-width apart. Keep your arms relaxed by your sides. First, master the pelvic tilt: gently flatten your lower back against the floor by tightening your lower abdominal muscles (imagine drawing your belly button toward your spine). Hold for 5 seconds, then release. Once that’s comfortable, progress to the bridge: from the tilted position, slowly lift your hips toward the ceiling, forming a straight line from knees to shoulders. Squeeze your glutes at the top. Hold for 3-5 seconds, then lower vertebra by vertebra. Do 8-10 repetitions. This directly targets the glutes and hamstrings, which are crucial for pelvic stability.
#4: Seated Marching (Core & Hip Stability)
Sit tall on a firm chair, feet flat. Maintain a gentle pelvic tilt (a neutral, not arched, spine). Without rocking your torso or losing the tilt, slowly lift one foot an inch off the floor. Hold for 3 seconds, then lower with control. Alternate legs. Aim for 10-12 per side. This seems deceptively simple, but it challenges your deep core to stabilize your pelvis while your hip flexors move. It’s a safe way to build coordination without loading the spine. If you feel your back arching, stop and reset your posture—quality trumps quantity every time.
Practical Takeaway: Do your bridges on a yoga mat or carpet. Focus on the slow, controlled lowering phase—that’s where the real muscle-building happens. For seated marches, place your hands on your hips to feel for any unwanted rocking.
Exercise #5 & #6: Posture and Mobility Guardians
AS has a sneaky way of pulling you into a forward, stooped posture. The muscles in your chest tighten, and the muscles in your upper back weaken. Fighting this tendency is a daily practice. These two exercises are your counter-attack, designed to open the front of your body and remind your shoulder blades how to move. I often demonstrate these in my clinic by showing before-and-after photos of patients who’ve made them a habit—the difference in their standing posture, even without changes on an X-ray, is genuinely remarkable.
#5: The Doorway Chest Stretch
Stand in a doorway. Place your forearms on the doorframe with elbows bent at 90 degrees, forming a “goalpost” shape. Step one foot forward. Gently lean your body forward until you feel a comfortable stretch across your chest and the front of your shoulders. Keep your chin tucked and your spine tall—don’t arch your lower back. Hold for 30 seconds. Repeat 3 times. This directly combats the hunched-forward posture that comes from sitting and from AS-related stiffness in the rib joints. Breathe deeply into the stretch.
#6: Chin Tucks & Scapular Squeezes (The Desk Savior)
This is a two-part powerhouse. Sit or stand against a wall if possible. First, the chin tuck: look straight ahead, then gently draw your head straight back, as if making a double chin. You should feel a stretch at the base of your skull and a lengthening in the back of your neck. Hold for 5 seconds, release. Next, scapular squeezes: with arms at your sides, gently squeeze your shoulder blades together and down, as if trying to hold a pencil between them. Avoid shrugging your shoulders up to your ears. Hold for 5 seconds. Do 10 repetitions of each, alternating. This strengthens the muscles that pull your shoulders back.
Practical Takeaway: Set a phone alarm to do the chin tucks and scapular squeezes every hour if you work at a desk. Use the doorway stretch as a transition activity—after a work session or before you leave the house.
Exercise #7: The Most Overlooked Tool (Your Breath)
This might surprise you, but breathing is a core exercise for AS. Inflammation can affect the joints where your ribs attach to your spine and breastbone, making your chest feel tight and restricting lung capacity. Furthermore, pain leads to shallow, panicked breathing, which tenses every muscle. Diaphragmatic breathing is a game-changer. It massages your internal organs, activates your deep core (the transversus abdominis), and tells your nervous system to switch from “fight-or-flight” to “rest-and-digest.” It’s a direct line to calming systemic inflammation.
Here’s how: Lie on your back with knees bent, or sit comfortably. Place one hand on your chest and the other on your belly. Inhale slowly through your nose for a count of 4, focusing on letting the air fill your belly so the hand on it rises. The hand on your chest should move very little. Feel your ribcage expand sideways. Exhale slowly through pursed lips for a count of 6, gently drawing your belly button inward. Aim for 5-10 minutes daily. In my practice, I’ve seen this simple practice lower pain scores and anxiety levels more effectively than many people expect. It’s a tool you always have with you, especially useful during stressful moments or while waiting for medication to kick in.
Practical Takeaway: Pair your breathing practice with a regular activity, like during your morning heat application or right before bed. Use the exhale to consciously release tension in any area you feel gripping, like your jaw or lower back.
What to Do When You're in a Flare
Flares are the stormy weather of AS—unpredictable and draining. During these times, your exercise goals must shift completely. The objective is no longer “improvement” but “maintenance and comfort.” Pushing through a flare can prolong it. I tell my patients to think of it as their body saying, “Please, just be gentle.” Your routine should become minimalist. Stick to the gentlest range-of-motion exercises, perhaps only the knee-to-chest rocks and the cat-cow on your back from the morning routine. Even then, reduce the range and repetitions by half.
This is when heat becomes your best friend. Warm baths, showers, or heating pads can provide more relief than any exercise during acute inflammation. Focus on diaphragmatic breathing to manage pain and anxiety. Short, slow walks indoors may be all you can manage—and that’s enough. The most important thing is to listen without judgment. A flare is not a setback in your overall journey; it’s a temporary detour. Keep a symptom journal to track what might trigger flares (stress, poor sleep, certain foods) and adjust your plan with your rheumatologist. Remember, rest is not laziness; it’s a strategic part of healing during a flare.
Practical Takeaway: Create a “flare kit”: a heating pad, a comfortable yoga mat or blanket, a water bottle, and a playlist of calming music or guided meditations. When a flare hits, your decision-making energy is low—having a pre-planned, ultra-gentle routine removes the guesswork.
Moves to Approach with Caution
Not all popular exercises are friendly to an AS spine. The general rule is to avoid movements that force your spine into end-range flexion (forward bending) or heavy compression. Why? Because inflammation weakens structures, and these positions place excessive stress on the very joints and ligaments that AS targets. I’ve had to gently guide many enthusiastic patients away from certain yoga poses or gym exercises that were doing more harm than good.
High-Risk Moves: Toe-touches or sit-ups (they put huge pressure on the lower spine), deep twisting poses (especially if done quickly), heavy barbell squats and deadlifts, high-impact activities like running on concrete (can jar the spine), and exercises that involve hanging from the neck (like some inversion tables). Also, be wary of any practitioner who promises to “crack” or aggressively manipulate your spine. The ligaments in AS can be fragile, and such manipulation carries risk. Always choose a physiotherapist or trainer who has experience with inflammatory arthritis and emphasizes control and alignment over intensity.
Key Caution: If an exercise causes a sharp, pinching, or radiating pain, or leaves you significantly stiffer the next day, it’s not for you. Cross it off your list and don’t look back. Your exercise menu should be filled with options that leave you feeling mobilized, not battered.
Your Holistic Toolkit: Heat, Cold, and Mindset
Exercise is the cornerstone, but it’s not the whole building. Managing AS back pain effectively requires a multi-pronged approach. Heat is your go-to for chronic stiffness and pre-exercise warm-up. It increases blood flow and relaxes muscles. Use a heating pad, warm bath, or shower for 15-20 minutes. Cold therapy (ice packs) can be more effective for acute, hot, swollen joints or after an activity that might have irritated a specific spot. Apply for 10-15 minutes over a thin towel to protect your skin.
Then there’s mindset. Chronic pain is as much a neurological experience as a physical one. Practices like mindfulness meditation, gentle tai chi, or even simply spending time in nature can lower stress hormones like cortisol, which is a known inflammatory agent. I encourage patients to cultivate self-compassion. Speaking to yourself with kindness (“This is hard, but I’m doing my best”) is not fluffy advice—it changes your physiological stress response. Pair this with sleep hygiene (a firm mattress and a thin pillow to avoid neck flexion) and nutrition (an anti-inflammatory diet rich in omega-3s, fruits, and vegetables), and you build a formidable defense against AS symptoms.
Practical Takeaway: Experiment to see if you are a “heat” or “cold” person for general stiffness. For mindset, start with a free app like Insight Timer for a 5-minute daily guided meditation focused on body scan or breath awareness.
Building Your Sustainable Weekly Routine
Now, let’s weave these threads into a practical weekly plan you can start with. Consistency is built on realism, not idealism. A sample week might look like this: Daily (5-10 mins): Morning bed exercises (#1 & #2) + 5 minutes of diaphragmatic breathing (#7). Monday, Wednesday, Friday (20-25 mins): After a heat pack, perform the full sequence: Bridges (#3), Seated Marches (#4), Doorway Stretch (#5), Chin Tucks/Scapular Squeezes (#6). Finish with breathing. Tuesday, Thursday, Saturday: Focus on enjoyable movement—a 20-30 minute walk, gentle swimming, or a tailored yoga class. Sunday: Active rest—maybe just the daily breathing and a walk.
The key is to schedule it like an important appointment. Use phone reminders or a habit-tracking app. Start at 50% of what you think you can do. It’s better to finish feeling, “I could have done more,” than “I overdid it.” Progress is measured in months, not days. Celebrate non-scale victories: putting on socks with less hassle, turning to reverse the car more easily, sleeping through the night. This routine isn’t set in stone; it’s a framework. Adjust it based on your energy, pain levels, and flare status. The goal is to create a sustainable rhythm that supports your life for the long term.
Practical Takeaway: Block out time in your calendar for your three main weekly sessions. Treat them as unbreakable commitments to yourself. On low-energy days, honor the commitment by just doing the breathing and one stretch—showing up matters most.
Frequently Asked Questions (FAQ)
1. Can exercise cure my Ankylosing Spondylitis?
No, exercise cannot cure AS, as it is a chronic autoimmune condition. However, it is one of the most powerful tools you have to manage symptoms, prevent disability, maintain mobility, and dramatically improve your quality of life. It's a core part of treatment, alongside medication and other therapies.
2. How often should I do these exercises?
For best results, aim for a short daily routine (10-15 minutes) to combat morning stiffness, and a slightly longer session (20-30 minutes) 3-4 times a week for strength and posture. Consistency is far more important than duration.
3. Is walking good for AS?
Absolutely. Walking is excellent, low-impact cardiovascular exercise for AS. It promotes spinal extension and hip mobility. Aim for a brisk, upright walk on flat ground for 20-30 minutes most days. Use good shoes and start slowly if you're in a flare.
4. Should I do yoga or Pilates?
Both can be fantastic, but you must choose the right class. Look for instructors experienced with back issues or arthritis. Avoid styles that force deep flexion (forward folding) or twisting. Hatha, Iyengar, or restorative yoga and equipment-based Pilates (with a trained instructor) are often safe bets. Always inform the instructor about your AS.
5. What pain level is "normal" during exercise?
A mild stretching sensation or mild muscle fatigue is normal. Sharp, stabbing, or joint-specific pain is NOT. Pain should not increase during or after exercise. If you have increased pain lasting more than 2 hours after finishing, you likely overdid it. Scale back next time.
6. Can I lift weights with AS?
Yes, but with caution. Focus on light to moderate weights with higher repetitions to build endurance. Prioritize form over heavy loads. Avoid exercises that put excessive load on the spine (like heavy squats or deadlifts) unless under expert guidance. Strengthening your legs, arms, and back muscles is very beneficial.
7. I'm in a bad flare. What should I do?
Scale back to the gentlest range-of-motion exercises only (like the bed exercises). Focus on deep breathing and very gentle movement. Heat is your friend. The goal during a flare is not to improve, but to maintain minimal mobility and comfort. Listen to your body and rest more.
8. Will these exercises prevent spinal fusion?
While no guarantee, regular, full-range-of-motion exercises are the single best thing you can do physically to delay or minimize fusion. They keep the joints mobile and signal the body that the space is needed. Combined with proper medical treatment, they are your primary defense.
9. Where can I find a qualified therapist?
Look for a physiotherapist (physical therapist) who specializes in rheumatology, arthritis, or chronic pain. National organizations like the Spondylitis Association of America (SAA) or Arthritis Foundation often have directories. A good therapist will work with you, not just give a generic sheet.

Taking the Next Step
Living with AS means being the CEO of your own health. It requires partnership with your doctor, smart medication management, and a daily commitment to mindful movement. This isn't about achieving a perfect workout; it's about showing up for your spine every single day, even when it's hard. The exercises outlined here—from the gentle morning knee rocks to the empowering core bridges and the calming breath work—are your toolkit. Start with just one. Maybe today, it's the 3-minute bed routine. Tomorrow, add in the diaphragmatic breathing. Build slowly, listen intently to your body's feedback, and celebrate small victories. The goal is not a rigid, fused spine, but a body that remains as fluid and capable as possible. You have the power to influence that outcome significantly, starting with your very next move.
