Lower back pain from sitting usually comes from staying still too long, not from one “bad” posture. So the simplest fix is to get up and move about every 30 minutes, and then strengthen your hips, glutes and core two or three times a week with easy moves like glute bridges, bird dogs and hip hinges.

I’ve spent over 30 years of personal training in San Diego, and many of the people I coach in my private Bay Park studio sit for a living. Office workers, remote workers, drivers and students all tend to ask me the same questions. Here’s the practical, movement-first approach I use, plus clear signs that it’s time to see a doctor instead.

Why do you get lower back pain from sitting?

Your spine and the muscles around it like to move. When you sit for hours, the same tissues stay in one position, and they get stiff and achy. In other words, the problem is usually the lack of change, not the chair itself.

In addition, long days at a desk often go hand in hand with less movement overall. For example, your glutes do very little while you sit, and your hip flexors stay in a shortened position. As a result, standing up after a long meeting can feel creaky. The World Health Organization’s physical activity guidance advises every age group to limit time spent sitting, and it notes that any amount of movement is better than none.

Keep in mind that back pain has many possible causes. That’s why this article covers exercise and daily habits only. It isn’t a diagnosis, and a doctor should check pain that is severe, lasting or unusual.

What exercises help lower back pain from sitting?

These are six simple moves I like for people who sit all day. They need no equipment, and you can do them at home or near your desk. Start with 1 to 2 sets of each, move slowly, and stay in a range that feels comfortable. Also, stop any exercise that sharply increases your pain.

  • Walking break (2 to 5 minutes): First, stand up and walk. It’s the easiest way to change position and get blood moving, so it’s the first thing I recommend.
  • Glute bridge (8 to 12 reps): Lie on your back with your knees bent. Then squeeze your glutes and lift your hips until your body forms a straight line from knees to shoulders.
  • Bird dog (6 to 8 reps per side): On hands and knees, reach one arm forward and the opposite leg back. Keep your hips level, as if a glass of water sits on your lower back.
  • Dead bug (6 to 8 reps per side): Lie on your back with arms up and knees bent at 90 degrees. Slowly lower the opposite arm and leg while your lower back stays gently against the floor.
  • Hip hinge (10 reps): Stand tall, soften your knees, and push your hips back as if closing a car door with your backside. This teaches you to bend from the hips, which helps when you lift anything.
  • Half-kneeling hip flexor stretch (30 seconds per side): Kneel on one knee, tuck your tailbone slightly, and shift forward until you feel a gentle stretch in the front of the hip.

For instance, a simple routine is a walking break every 30 to 60 minutes, plus bridges, bird dogs and dead bugs before work. After that, add the hip hinge and hip flexor stretch at lunch. If breathing and bracing feel unfamiliar, my guide to breathing and bracing explains how to set your core before you move.

How often should you get up from your desk?

Mayo Clinic’s back pain guidance suggests changing position at least every 30 minutes. That’s a realistic target for most desk workers, because it doesn’t require a full workout.

Here are easy ways to build movement into a workday:

  • Set a quiet timer for every 30 minutes, then stand, stretch or refill your water.
  • Take phone calls standing up or while walking.
  • Use a walking meeting for one-on-one conversations.
  • Also, park farther away or take the stairs when you can.

Similarly, if you work from home, a short walk around the block between video calls counts. The goal is frequent change, not perfection.

Does posture matter for lower back pain from sitting?

Posture matters less than most people think. In fact, there’s no single perfect way to sit. A position that feels fine for 10 minutes can feel stiff after two hours, simply because you haven’t moved. That’s why I like the saying that your best posture is your next one.

Still, a comfortable setup helps. For example, Mayo Clinic recommends a chair with good lower-back support, and a small pillow or rolled towel behind your lower back can help. Keep your feet flat and your screen at eye level, so you aren’t reaching or craning. However, even a great chair can’t replace getting up and moving.

How does strength training help your back long term?

Short movement breaks help you feel better during the day. Meanwhile, regular strength training builds a body that handles sitting, lifting and everyday life more easily. A large Cochrane review of exercise for chronic low back pain (249 studies) found that exercise probably reduces pain compared with no treatment or usual care. Its effect on day-to-day function was smaller.

Because of that, I focus on progressive strength work for the hips, legs and trunk: squats to a box, hip hinges, carries and rows. In addition, the WHO recommends at least 150 minutes of moderate activity each week for adults. So, if lower back pain from sitting is part of your week, two or three strength sessions plus daily walks are a strong place to start. For more ideas on moving well, see my post on mobility exercises.

When should you see a doctor or physical therapist?

I’m a personal trainer, so I coach exercise and movement. I don’t diagnose or treat injuries. See a doctor or physical therapist if your back pain lasts more than a few weeks, or if it comes with any of these red flags:

  • Numbness, tingling or weakness in one or both legs
  • Pain that spreads down a leg, especially below the knee
  • Pain at night or at rest that doesn’t ease with a change of position
  • Pain after a fall, a blow to the back or another injury
  • New problems controlling your bladder or bowels (seek care right away)
  • Back pain with fever or unexplained weight loss

After you’ve been cleared, or once physical therapy ends, a coach can help you keep building strength. That’s exactly what my strength training after physical therapy program is for.

Frequently Asked Questions

Is sitting all day bad if I work out?

Working out is great, but it doesn’t fully cancel out hours of stillness. The World Health Organization advises limiting sedentary time in addition to getting regular exercise. So keep your workouts, and also break up long sitting spells with short walks or stretches. Even two to five minutes of movement every half hour makes a long workday feel noticeably better for many desk workers.

Can a standing desk fix lower back pain?

A standing desk can help because it makes changing position easier. However, standing still all day can feel just as stiff as sitting still. The real benefit comes from switching between sitting, standing and walking throughout the day. If you use one, alternate positions often, wear supportive shoes, and keep doing your strength work a few times a week.

Should I stretch or strengthen a sore lower back?

Both have a place. Gentle stretches, like the half-kneeling hip flexor stretch, can make you feel looser after sitting. Meanwhile, strengthening your glutes, legs and core builds lasting support for your back. As a coach, I treat stretching as the warm-up and strength training as the main course. Stop any move that sharply increases your pain, and check with a doctor if pain persists.

Can a personal trainer help with lower back pain from sitting?

A personal trainer can help you move more, build strength and use good technique, which many desk workers find helpful. However, a trainer shouldn’t diagnose or treat pain. If your pain is severe, lasting or comes with red flags, see a doctor or physical therapist first. After that, a coach can work alongside their advice to keep you training safely.

How long should a movement break be?

A movement break can be short. Two to five minutes of walking, a few bridges, or a quick hip flexor stretch is enough to change position and get your blood moving. In fact, frequent short breaks are usually easier to stick with than one long session. Aim for a break about every 30 minutes, then add longer strength workouts two or three times a week.
