The best exercises for lower back pain are ones that strengthen your core and glutes while gently improving spinal mobility. The American College of Physicians recommends exercise as a first-line treatment for chronic low back pain, ahead of medication, based on moderate-quality evidence. The right routine doesn’t need to be complicated: a handful of targeted movements done consistently can make a meaningful difference in both pain and function.
Why Exercise Works for Back Pain
Lower back pain often stems from weak or inactive muscles that are supposed to stabilize your spine. The deepest layer of your abdominal wall wraps from your lower ribs to your pelvis and acts as a natural brace for your lumbar spine. When this muscle is strong, it provides dynamic stabilization, meaning it supports your spine during movement, not just when you’re sitting still. Strengthening it has been shown to both reduce and prevent lower back pain.
Your glutes play a similar role. The muscles on the side and back of your hips normally keep your pelvis level and stable. When they stop firing properly, a pattern sometimes called “gluteal amnesia,” your lower back compensates for the imbalance. That compensation creates extra load on spinal structures that weren’t designed to bear it, leading to pain in the back, hips, and sometimes even the knees and ankles.
A conditioning program targeting these areas, done two to three days a week, will maintain strength and range of motion in your back. The American Academy of Orthopaedic Surgeons recommends continuing a spine conditioning program for four to six weeks to see lasting results.
Core Stabilization Exercises
Core stabilization exercises require you to hold your body in a controlled position, often while slowly moving your arms or legs. They train the deep muscles around your spine rather than the surface-level “six pack” muscles.
Bird Dog
Start on all fours with your knees under your hips and hands under your shoulders. Engage your abdominal muscles to keep a neutral spine, then raise your right arm and left leg simultaneously. Keep your shoulders and hips parallel to the floor, resisting the urge to rotate or tilt. Hold for two to three seconds, then return and switch sides. Aim for 8 to 12 repetitions on each side. If you’re unsure about your form, place a light object like a foam roller across your lower back. If it rolls off, you’re twisting too much.
Dead Bug
Lie on your back with both arms pointing toward the ceiling and your knees bent at 90 degrees, shins parallel to the floor. Press your lower back flat into the ground and hold it there throughout the movement. Slowly extend your left arm overhead while straightening your right leg toward the floor, hovering just above it. Return to the starting position and alternate sides. Work for 15 to 60 seconds. The key is that your back should never arch off the floor. If it does, you’ve gone too far.
Plank
From a forearm position with elbows under your shoulders, lift your body into a straight line from head to heels. Keep your core engaged and your hips level. Don’t let your lower back sag or your hips pike upward. Hold as long as you can maintain proper form, even if that’s only 10 to 15 seconds at first. Quality matters far more than duration here.
Toe Taps
Lie on your back with knees bent at 90 degrees, feet lifted off the floor. Slowly lower one foot to tap the ground, making sure your lower back stays pressed into the floor and doesn’t arch. Return that leg and repeat on the other side. Continue alternating for 15 to 60 seconds. This exercise looks simple, but it isolates the deep stabilizers effectively when done with control.
Stretches for Spinal Mobility
Stiff spines tend to be painful spines. Gentle mobility work helps reduce stiffness, improve posture, and circulate synovial fluid, the substance that cushions your joints and reduces friction when you move.
Cat-Cow
Start on all fours in a tabletop position. As you inhale, arch your back and let your belly drop toward the floor, lifting your head and tailbone (the cow position). As you exhale, round your spine toward the ceiling, tucking your chin and tailbone (the cat position). Flow between these two positions with your breath, focusing on creating space between each vertebra. Nothing should feel strained. This movement activates not just your belly muscles but also your sides and lower back, encouraging motion through your entire core. It also promotes deep, steady breathing, which helps reduce tension.
Knee to Chest
Lie on your back with both knees bent and feet flat on the floor. Pull one knee gently toward your chest, holding behind the thigh or at the shin, until you feel a comfortable stretch in your lower back and hip. Hold for 15 to 30 seconds, then switch sides. The AAOS recommends 3 sets of 10 repetitions daily for this stretch. You can also pull both knees in at once for a slightly different stretch through the lumbar spine.
Glute Strengthening Exercises
Glute Bridge
Lie on your back with knees bent and feet flat on the floor, hip-width apart. Press through your heels to lift your hips until your body forms a straight line from shoulders to knees. Squeeze your glutes at the top and hold briefly before lowering back down. Start with 5 repetitions and work upward. Focus on driving the movement from your glutes, not your lower back. If you feel your back doing most of the work, try squeezing your glutes before you lift.
Clamshell
Lie on your side with knees bent at about 45 degrees, hips stacked. Keeping your feet together, open your top knee toward the ceiling like a clamshell opening. Don’t let your pelvis roll backward. The range of motion is smaller than most people expect. Lower back down with control. This targets the gluteus medius, the hip muscle most responsible for pelvic stability. When this muscle is weak, your lower back picks up the slack during walking, standing, and virtually every other upright activity.
How Often and How Long
For general maintenance, exercising two to three days a week is enough to maintain back strength and mobility. Many of the stretches and simpler stabilization exercises can be done daily. A reasonable starting program might look like this: cat-cow and knee-to-chest stretches as a warm-up, followed by bird dogs, dead bugs, and glute bridges as your main work, finishing with a plank hold.
Plan on sticking with the routine for at least four to six weeks before judging whether it’s working. Back pain responds to consistency, not intensity. Starting with fewer repetitions and building gradually is more effective than pushing hard on day one and being too sore to continue on day three. If a particular exercise increases your pain during or after, skip it for now rather than pushing through it.
Exercise vs. More Invasive Options
For people considering whether exercise is really “enough,” the evidence is reassuring. In a study of 169 people with lumbar spinal stenosis, a common structural cause of back pain, researchers compared surgery to physical therapy. Two years later, there was no difference in pain or physical function between the two groups. But 25% of the surgery group experienced complications like repeat surgery or infection, while only 10% of the physical therapy group reported any worsening of symptoms. Exercise carries far less risk and, for many conditions, produces equivalent long-term results.
Yoga and tai chi also have enough evidence behind them that the American College of Physicians lists both as recommended first-line treatments alongside conventional exercise. If a structured routine of bird dogs and bridges doesn’t appeal to you, a yoga or tai chi class focused on gentle movement can deliver similar benefits through a different format.
