Chronic low back pain is one of the most common conditions I treat. It's also one of the most over-hyped topics in online health content — every other Instagram video promises the one miracle exercise that will fix your back.
There isn't one. But there are a handful of exercises that research consistently supports and that I prescribe to most of my patients with non-specific low back pain. Here are five, along with honest context on what they actually do.
One caveat before we start: these are general exercises for non-specific mechanical low back pain — the kind that's driven by movement patterns and muscle function. If your pain came from a specific injury, radiates down your leg, is associated with numbness or weakness, affects your bowel or bladder, or is severe and unrelenting, you need an in-person evaluation before doing exercises from the internet. See a physician or physical therapist first.
1. The cat-cow
What it does: Gently mobilizes the spine through flexion and extension, helping you map out the full range of motion your back is capable of. Often the first thing patients with stiff, guarded backs need.
How to do it: On hands and knees, alternate between arching your back upward (cat) and letting it sag downward while lifting your head and tailbone (cow). Slow, controlled, 8–10 repetitions. Breathe into each position.
When to skip: If one direction reproduces sharp pain, back off. Some acute conditions don't tolerate flexion or extension well.
2. The bird-dog
What it does: Trains the deep stabilizing muscles of the spine and hip to activate together while limbs move. This is the kind of control most patients with chronic back pain have lost.
How to do it: On hands and knees, slowly extend one arm forward and the opposite leg backward. Hold briefly, return, alternate sides. The goal is stability — your trunk shouldn't rotate, tilt, or sag. 8–10 per side.
Why most people do it wrong: They arch their back when extending the leg, or twist when extending the arm. Doing it slowly and watching yourself in a mirror or video helps. It's a small, controlled movement — not a big reach.
3. The glute bridge
What it does: Strengthens the glutes — which in almost every chronic back pain patient I see are underused. Weak, poorly-firing glutes force the lower back to do work it shouldn't.
How to do it: Lie on your back, knees bent, feet flat on the floor. Press through your heels and lift your hips until your body forms a straight line from shoulders to knees. Squeeze the glutes at the top, lower slowly. 10–15 reps.
Progression: Once the two-leg bridge is easy, try single-leg bridges — lift one leg off the ground and bridge up using the other. This is where you'll find out whether one side is weaker than the other, which is almost always the case.
4. The side plank (modified if needed)
What it does: Trains the lateral core — the quadratus lumborum, obliques, and glute medius — all of which are critical for spine stability during everyday movement.
How to do it: Lie on your side, propped up on your elbow. Keep your body in a straight line. If a full side plank is too much, drop the bottom knee to the floor (modified version). Hold 15–30 seconds, build up over time.
Why this one matters: Side planks have been shown in research by Stuart McGill's lab to be particularly well-tolerated by patients with low back pain — they load the core without loading the spine into flexion, which is often the problem position.
5. The hip flexor stretch
What it does: Lengthens the hip flexors, which in desk-bound patients are often chronically tight and contribute to an anterior pelvic tilt that loads the lower back.
How to do it: Kneel on one knee with the other foot in front, forming a 90-degree angle. Tuck your pelvis under (think: tail between your legs) and gently shift your weight forward. You should feel a stretch in the front of the hip on the kneeling side. Hold 30 seconds, 2–3 reps per side.
Common mistake: Letting the lower back arch during the stretch. That puts the stretch in the wrong place and can irritate the back. The pelvic tuck is what makes this exercise effective.
A realistic schedule
These aren't exercises you do once and feel better. They're part of a daily or near-daily practice. Most patients I work with start with 10–15 minutes, 5–6 days a week. That's enough to produce meaningful changes in most chronic, non-specific low back pain over the course of 6–8 weeks.
If you're not improving after a month of consistent work — or if symptoms are getting worse — that's your signal that something else is going on and it's time for an evaluation. Not every back needs the same exercises, and occasionally what looks like mechanical back pain is actually something else.
When to see a physical therapist
If back pain has been going on for more than a few weeks, is interfering with sleep or work, or keeps recurring — an evaluation gives you a real diagnosis and a plan that fits your specific situation. Generic online exercises, even good ones, can only take you so far without someone actually watching how you move.
