Your alarm goes off, you swing your legs over the side of the bed, and your lower back takes a moment to agree to the plan. The first minutes of the day are when many backs feel their worst, and the instinct is to move as little as possible until it passes. For most stiff mornings, a few gentle lower back stretches are the better answer, and the case for them is stronger than the instinct to stay still.
Why your back feels stiffest in the morning
Stillness is most of the story. In a 2025 Cleveland Clinic article on morning back pain, pain management specialist Dr. Tara-Lin Hollins explains that when the body stays immobile for hours, stiffness settles in and inflammation can build up. Sleep position and an unsupportive mattress can add their share. The encouraging part is the usual pattern: stiffness that is worst on waking and eases once you start moving is common, and it tends to respond to exactly that, movement.
Why gentle movement beats waiting it out
Back care has spent decades moving away from bed rest and toward staying as active as symptoms allow. When the American College of Physicians updated its low back pain guideline in Annals of Internal Medicine in 2017, it recommended nondrug care first for new episodes, options like superficial heat, massage, and spinal manipulation, and reassured patients that most acute episodes improve over time regardless of treatment. For pain that lingers, exercise is among its first-line treatments. Gentle mobility work is the low-stakes end of that spectrum: a way to keep a stiff back moving without loading it. Strengthening matters too, but it is a separate project from the morning routine covered here.
Four gentle stretches that fit a stiff morning
These four movements take the lower back and hips through their basic directions, bending, arching, and rotating, without resistance. A rug or a firm mattress works, and so does whatever range feels comfortable today.
- Knee-to-chest: lying on your back, draw one knee toward your chest with your hands behind the thigh, feel the low back and hip soften, then switch legs. Cleveland Clinic's morning back pain guidance includes this one.
- Cat-camel, often called cat-cow: on hands and knees, slowly alternate between rounding your back toward the ceiling and letting it sag toward the floor. Stay well inside comfort at both ends; the goal is smooth motion, not maximum arch.
- Windshield wipers: lying on your back with knees bent and feet wider than your hips, let both knees fall slowly toward one side, return to center, then go the other way. This gives the lower back and hips a gentle rotation.
- Seated open book: sitting tall on the edge of the bed with arms crossed over your chest, rotate your upper back to one side, let your head follow, then turn the other way. Freeing up the mid-back means the lower back is not asked to do all the twisting.
How long should you hold each stretch?
Harvard Health Publishing's guidance on stretching for low back pain suggests holding a stretch for 10 to 30 seconds at first, building toward a minute over a period of days, and never bouncing. That fits the still positions here, knee-to-chest and the end of each windshield wiper. For the moving drills, many clinicians use slow repetitions instead, and five to ten unhurried cycles of cat-camel or the open book is a common starting point. None of this is a prescription. If you are working with a physical therapist, the right dose is the one they have tailored to you, and as Christina Ruggeri, a physical therapist at Harvard-affiliated Spaulding Rehabilitation Hospital, puts it in that same guidance, the aim is to be gentle enough that you help your muscles rather than injure them.
Comfort versus pain: where the line sits
A useful stretch feels like tension that eases as you breathe and settle in, a pulling sensation in muscle rather than a warning. Pain that sharpens as you move, or that spreads into the buttock or down a leg, is a signal to shrink the range, not push through it. Harvard's guidance is blunt on this point: stop if your pain gets worse during a stretch. On a stiff morning it is reasonable to start with half of yesterday's range and let the movement earn its way deeper. Stiffness that fades over a few gentle repetitions is behaving like ordinary morning stiffness; pain that climbs with each one is not.
Some backs should be assessed before they are stretched. Check with your physical therapist or clinician first if your pain follows a fall or accident, comes with numbness or weakness in a leg, fever, or any change in bladder or bowel control, or if you have a diagnosed spine condition such as severe spinal stenosis. And for ordinary morning pain, Cleveland Clinic's advice is worth keeping: if it is getting worse, or shows up most mornings for two or three months, stop stretching around it and have it looked at.
