About 80 percent of people suffer from low back pain at some point in their lives.
t shows up after a long drive, a weekend of yard work, or for no obvious reason at all. There are plenty of common causes of back pain, but one of the most overlooked is also one of the easiest to work on: a weak core.
The good news is you don’t need a gym or an hour a day. The seven exercises below take about 10 minutes, need no equipment, and are a solid place to start.
Quick Reminders:
- Your core is more than your abs. It includes your deep abdominals, obliques, lower back muscles, glutes, and hips.
- When those muscles are weak, your lower back does work it wasn’t built for.
- Slow, controlled exercises like planks, dead bugs, and bird dogs build the kind of strength that protects your spine.
- Aim for three or four sessions a week. Consistency beats intensity.
How a Weak Core Leads to Back Pain
Think of your core as a natural brace that wraps around your spine. When it’s strong, it shares the load every time you bend, lift, twist, or sit.
When it’s weak, other areas pick up the slack. Your hip flexors tighten, your pelvis tips forward, and your lower back muscles stay switched on all day. That pattern gets worse with long hours of sitting, which is why so many desk workers end up with a stiff, achy back by mid-afternoon.
Over time, that extra strain raises your risk for sprains, strains, and more stubborn problems like a herniated disc or sciatica.
Before You Start
These exercises should feel like work, not pain. Move slowly, keep breathing, and stop if anything makes your symptoms worse. If you feel numbness, tingling, or pain that travels down your leg, skip the workout and talk with a provider first.
7 Core Exercises for Lower Back Pain
1. Pelvic Tilt
This is the best starting point if your back is sore right now.
- Lie on your back with your knees bent and feet flat on the floor.
- Gently tighten your stomach and press your lower back into the floor.
- Hold for 5 seconds, then relax.
- Repeat 10 times.
2. Dead Bug
The dead bug teaches your core to stay steady while your arms and legs move, which is exactly what it has to do all day.
- Lie on your back with your arms reaching toward the ceiling.
- Lift your legs so your hips and knees are bent at 90 degrees.
- Keep your lower back in contact with the floor.
- Slowly lower one heel toward the floor, tap lightly, and return.
- Switch legs. Do 2 sets of 5 on each side.
3. Bird Dog
- Start on your hands and knees with your back flat.
- Tighten your core, then reach one arm forward and the opposite leg straight back.
- Hold for 2 to 3 seconds without letting your hips rotate.
- Return to the start and switch sides. Do 2 sets of 8 on each side.
4. Glute Bridge
Your glutes are part of your core, and when they’re weak, your lower back takes over. For a closer look at form, see our guide on how to perform a glute bridge.
- Lie on your back with your knees bent and feet hip-width apart.
- Squeeze your glutes and lift your hips until your body forms a straight line from shoulders to knees.
- Hold for 2 seconds, then lower slowly.
- Do 2 sets of 10.
5. Forearm Plank
- Lie on your stomach with your elbows directly under your shoulders.
- Push up onto your forearms and toes so your body forms a straight line.
- Keep your core tight and don’t let your hips sag.
- Hold for 20 to 30 seconds. Rest and repeat 3 times.

6. Side Plank
- Lie on your side with your elbow directly under your shoulder.
- Stack your legs and lift your hips so your body forms a straight line.
- Keep your hips stacked and avoid twisting.
- Hold for 20 to 30 seconds on each side. Repeat twice.
7. Superman
- Lie face down with your arms stretched out in front of you.
- Tighten your core, then lift your arms and legs a few inches off the floor.
- Hold for 2 seconds and lower with control.
- Do 2 sets of 5.
How Often Should You Do Core Exercises?
Three or four times a week is plenty for most people. Start with one round, and add a second as it gets easier. Most people notice a difference in how their back feels within a few weeks of staying consistent.
When you’re ready for more, try these exercises for core stability.
Don’t Forget Your Hips
A strong core works best with hips that move well. Tight hip flexors pull on your pelvis and lower back, and they can undo a lot of your hard work. Pair this routine with a few hip flexor stretches.

When Exercise Isn’t Enough
Core work is great for prevention and mild aches. But if your back pain has lasted more than a couple of weeks, keeps coming back, or is getting in the way of work, sleep, or the things you love, it’s time to find out what’s really going on.
Get checked right away if you have pain after a fall or accident, pain with fever, new weakness in your legs, or any loss of bladder or bowel control.

Frequently Asked Questions
Can a weak core cause lower back pain?
Yes. When your core muscles can’t support your spine, your lower back muscles and joints take on extra load. Over time that can lead to stiffness, strain, and pain.
What is the best core exercise for lower back pain?
There isn’t a single best one, but dead bugs, bird dogs, and planks are great starting points because they build strength without bending or twisting your spine.
Are sit-ups good for back pain?
Usually not. Sit-ups and crunches put repeated bending pressure on your lower back and mostly work the surface abs. Stability exercises like the ones above are a better fit.
Should I do core exercises if my back hurts right now?
Gentle movement often helps, so start with pelvic tilts and stop if your pain gets worse. If the pain is severe or travels down your leg, see a provider before you exercise.
How long does it take to strengthen your core?
Most people feel more stable within a few weeks of doing these exercises three or four times a week. Lasting strength takes a couple of months of steady work.
