A handful of simple stretches, done consistently, can relieve lower back stiffness and reduce pain. The best routines target not just the lower back itself but also the hips, glutes, and core muscles that support the spine. Most of these stretches take five to fifteen minutes and require nothing but floor space.
Why Your Lower Back Gets Tight
The muscles running along your lumbar spine, particularly the deep stabilizers and the broad muscles on either side of the spine, work together to extend, bend, and rotate your trunk. When any of these muscles shorten or stiffen from prolonged sitting, poor posture, or lack of movement, they pull unevenly on the spine and create pain. The quadratus lumborum, a deep muscle connecting your lowest rib to your pelvis, is especially important because it cooperates with nearly every other muscle in the region during bending and extending.
Tight hip flexors compound the problem. Since the hips connect your lower back to your legs, stiff hip flexors prevent your pelvis from rotating properly, which forces your lower back to compensate. Weak glutes and core muscles make this worse by shifting extra stabilization work onto the hip flexors, tightening them further. That’s why a good lower back routine includes the hips and pelvis, not just the spine.
Knee-to-Chest Stretch
Lie on your back with both knees bent and feet flat on the floor. Pull one knee toward your chest and hold it for five to ten seconds. Return to the starting position and repeat with the other leg. Do this five to ten times per leg. This stretch gently releases tension in the muscles along the lower spine and helps decompress the lumbar area. It’s one of the easiest stretches to start with if your back is particularly stiff or sore.
Pelvic Tilts
From the same position (on your back, knees bent, feet flat), gently flatten your lower back against the floor by tightening your abdominal muscles. Hold for five to ten seconds, then relax. Repeat five to ten times. Pelvic tilts are subtle. You won’t see much movement, but you’ll feel your core engage and the small muscles along your spine activate. This stretch doubles as a strengthening exercise for the deep muscles that stabilize your lower back.
Lower Back Rotational Stretch
Lie on your back with knees bent and feet on the floor. Keeping your shoulders flat, gently roll both knees to one side and hold for five to ten seconds. Return to center, then roll to the other side. Repeat two to three times per side. This stretch targets the muscles that rotate your trunk and helps restore mobility when your lower back feels locked up. A seated version works too: sit in a chair, cross one leg over the other, and rotate your torso toward the crossed knee, holding for ten seconds. Do three to five repetitions on each side.
Cat Stretch
Get on your hands and knees with your wrists under your shoulders and knees under your hips. Slowly round your back toward the ceiling, tucking your chin toward your chest (like a cat arching). Hold briefly, then let your back sag gently toward the floor while lifting your head. Repeat three to five times. This one is especially useful first thing in the morning when your spine feels compressed from sleep, because it moves your lower back through its full range of flexion and extension.
Child’s Pose
From hands and knees, sit your hips back toward your heels while reaching your arms forward along the floor. Let your forehead rest on the ground and hold for 30 seconds to two minutes. Child’s pose stretches both the muscles along the lumbar spine and the quadratus lumborum simultaneously. Research on this yoga-based stretch has shown it effectively relaxes shortened muscles around the lumbar region, relieving mechanical stress on the spine.
Bridge
Lie on your back with knees bent and feet flat on the floor. Squeeze your glutes and raise your hips four to six inches off the floor. Hold long enough to take three deep breaths, then lower back down. Start with five repetitions and gradually work up to 30 over several weeks. The bridge strengthens your glutes and the muscles along your spine while gently stretching the hip flexors at the front of your thighs. Weak glutes are one of the most common contributors to lower back pain, so this exercise pulls double duty.
Half-Kneeling Hip Flexor Stretch
Kneel on the floor and bring one foot forward so your front thigh is parallel to the ground, knee bent at 90 degrees, foot flat. Keep your back knee on the floor with your shin pointing straight behind you. Place your hands on your hips, tuck your pelvis under by squeezing your glutes, and shift your weight forward until you feel a stretch through the front of your back thigh and groin. For a deeper stretch, raise the arm on the kneeling side overhead and lean slightly toward the opposite side. Hold for 30 seconds on each side and repeat for three sets.
This stretch directly addresses the hip-flexor-to-lower-back connection. If you sit for most of the day, your hip flexors are likely shortened, and this is one of the most effective ways to lengthen them.
90/90 Stretch
Sit on the floor with your right leg in front of you, knee bent at 90 degrees, so the bottom of your foot faces the left wall. Extend your left leg out to the side, also bent at 90 degrees, with the bottom of that foot facing the wall behind you. Square your shoulders forward and sit tall. To check your posture, extend both arms straight in front of you. You should feel a deep stretch through your hips and glutes. Hold for 30 seconds, then switch sides.
This stretch targets the deep rotator muscles in your hips that, when tight, alter how your pelvis sits and create compensatory strain in the lower back. It can feel intense at first, so ease into the position gradually.
How Long and How Often
For static stretches like the knee-to-chest and hip flexor stretch, holding for five to 30 seconds per repetition is the general range. Shorter holds (five to ten seconds) work well when you’re doing more repetitions. Longer holds (30 seconds) work better when you’re doing fewer sets. The key is consistency rather than intensity.
A practical schedule: do your routine twice a day, aiming for about 15 minutes each session. Start with fewer repetitions and build up. For exercises like the bridge and pelvic tilts, beginning at five repetitions and gradually increasing to 30 over several weeks prevents soreness and lets your muscles adapt. The American College of Physicians recommends exercise, including stretching-based approaches like yoga, as a first-line treatment for chronic low back pain, ahead of medication.
When Stretching Isn’t Enough
Stretching alone addresses tightness and stiffness, but lasting relief usually comes from combining stretching with strengthening. Relaxing shortened muscles through stretching while also building strength in the muscles and ligaments that stabilize the spine produces better long-term outcomes than either approach alone. If your lower back pain is accompanied by numbness or tingling in your legs, pain that wakes you at night, or weakness in your feet, those symptoms point to something beyond muscle tightness and warrant a professional evaluation.
