Stretching your lower back, hips, and hamstrings can meaningfully reduce stiffness and pain, and clinical guidelines from the American College of Physicians recommend exercise-based approaches as the first line of treatment for chronic low back pain, before medication. The stretches below target the muscles most commonly involved in lumbar pain, and most take less than 15 minutes to complete.
Why Stretching Helps Lower Back Pain
When a muscle stays tight or shortened for long periods, it pulls on the structures around it. Your hip flexors are a perfect example: they originate along the lower lumbar vertebrae and run down to the pelvis and thigh bone. When they’re chronically tight from sitting, they tug on the lumbar spine with every step, creating pain that can radiate into the buttocks and sacrum. Stretching these muscles lowers their stiffness and resting tension, temporarily relieving that pull.
The relief is real but short-lived if you only stretch once. Research shows that two to eight minutes of stretching acutely reduces muscle stiffness, but baseline stiffness returns within about 20 minutes. That’s because a spring-like protein inside muscle fibers works to restore the muscle’s original resting length after it’s been lengthened. Consistent stretching over weeks, however, appears to create more lasting changes, potentially adding length to the muscle-tendon unit itself. This is why daily practice matters more than any single session.
Six Stretches Worth Doing Daily
Knee-to-Chest Stretch
Lie on your back with both knees bent and feet flat on the floor. Pull one knee toward your chest with both hands while tightening your abdominal muscles and pressing your spine into the floor. Hold for 15 to 30 seconds, then switch legs. Finish by pulling both knees to your chest at the same time. This stretch releases tension across the lower back and glutes, and it’s gentle enough to do first thing in the morning when your joints are stiffest.
Lower Back Rotational Stretch
From the same starting position (on your back, knees bent, feet flat), keep your shoulders pressed firmly into the floor and slowly roll both bent knees to one side. Hold for 5 to 10 seconds, return to center, then roll to the other side. Repeat two to three times per side. This targets the small rotational muscles along the spine and improves lumbar mobility, which tends to decline the longer pain persists.
Hip Flexor Stretch
Sit on the edge of a bed or sturdy table and lie back, pulling both knees toward your chest. Then let one leg dangle down off the edge while holding the other knee. You’ll feel a stretch in the front of the dangling leg’s hip and into the lower back. Hold for 20 to 30 seconds per side. This directly targets the hip flexor group, which is the most common contributor to posture-related lumbar pain in people who sit for long hours.
Hamstring Stretch
Lie on your back and raise one leg, keeping the other foot flat on the floor. Grasp the back of your raised thigh and slowly straighten that knee until you feel a pull along the back of your thigh. Hold for 20 to 30 seconds, then switch. Tight hamstrings tilt the pelvis backward and flatten the natural lumbar curve, which loads the lower spine unevenly. Loosening them takes pressure off the discs and joints.
Lumbar Extension
Stand tall with your hands on your hips. Gently lean backward, allowing your lower back to arch. Use your hands to guide the motion. Hold for a few seconds and return upright. This is a good countermovement if you spend most of the day bent forward over a desk, and physical therapists frequently use it as a quick reset between longer stretching sessions.
Child’s Pose
Kneel on the floor, sit your hips back toward your heels, and walk your hands forward along the ground until your forehead rests on the floor (or close to it). Let your belly drop between your thighs and breathe deeply. This gently opens the lower back, stretches the muscles along the spine, and provides a mild decompression effect. If your knees or hips are stiff, place a rolled blanket or pillow between your thighs and calves for support, or rest your forehead on a yoga block or folded towel.
How Long to Hold Each Stretch
Hold each position for 15 to 30 seconds and repeat two to three times per side. Shorter holds don’t produce enough of a stiffness reduction to be useful, while holding beyond 60 seconds doesn’t add much benefit for most people. The total routine should take roughly 10 to 15 minutes. The Mayo Clinic suggests doing the full sequence once in the morning and once in the evening for the best results.
Morning Stretching vs. Evening Stretching
Your muscles and joints are at their tightest first thing in the morning after lying still all night. That stiffness makes morning stretching feel harder, but it’s also when you need it most. Gentle stretches like the knee-to-chest and lower back rotation are safe morning choices because they’re done lying down and don’t require much range of motion.
Flexibility peaks around 7:00 PM, so evening sessions allow you to stretch more deeply. Going through your routine before bed also relaxes the muscles enough to prevent them from tightening up as much overnight, which can reduce that morning stiffness the next day. If you can only pick one time, the morning matters more for pain relief; if you can do both, the combination is noticeably more effective within a few weeks.
Stretching Alone May Not Be Enough
Stretching provides real relief, but a systematic review of exercise approaches found that core strengthening exercises reduced chronic lower back pain slightly more than stretching, flexibility work, yoga, or aerobic exercise alone. The difference was modest (about 5 to 6 points on a 100-point pain scale), but it’s consistent. The practical takeaway is that pairing your stretching routine with basic core work, like abdominal bracing or bird-dogs, tends to produce better long-term outcomes than stretching by itself.
Physical therapy for lower back pain almost always combines both: stretching the hip flexors, hamstrings, and lumbar muscles to reduce tightness, plus strengthening the spinal and hip muscles to provide better support. A foam roller can help with muscle spasms in the hamstrings, glutes, hip flexors, and outer thighs if you can tolerate the pressure.
When Pain Runs Down Your Leg
If your lower back pain radiates down one leg, the issue may involve a nerve rather than just tight muscles. Standard static stretching still helps, but a technique called nerve gliding (sometimes called nerve flossing) can be more effective for this type of pain. Research published in the European Journal of Applied Physiology found that nerve gliding produced a greater increase in hamstring flexibility and reduced nerve tension more than static stretching alone.
A basic sciatic nerve glide involves sitting on a chair, slowly straightening one knee while tilting your head back, then bending the knee while tucking your chin. The movement slides the nerve through its surrounding tissue rather than holding it under sustained tension. If your pain includes numbness, tingling, or weakness in the leg, or if you notice changes in bladder function or loss of sensation in the groin area, these are red flags that warrant prompt medical evaluation rather than self-treatment with stretching.
Making Stretches Easier With Props
Limited flexibility shouldn’t stop you from starting. A yoga block, a stack of books, or a firm pillow can bridge the gap between where your body is now and where a stretch asks it to be. For the hamstring stretch, looping a towel or belt around the ball of your foot lets you straighten the leg without straining to reach it. For child’s pose, a bolster or rolled blanket under the torso or between the thighs takes pressure off stiff knees and hips. The goal is to feel a moderate pull in the target area, not pain. If a stretch hurts, back off the intensity or use a prop to reduce the range of motion until your flexibility improves.
