Why Back Pain Happens — And How Exercise & Physical Therapy Can Help

Back pain is one of the most common health complaints in the world. According to the World Health Organization (WHO), more than 619 million people globally are affected by low back pain, and that number is expected to rise as populations age and activity patterns change. Low back pain is also the leading cause of disability worldwide, limiting quality of life and daily movement for millions every year.

In the United States alone, estimates suggest that up to 80% of adults will experience low back pain at some point in their lives. At any given time, roughly 1 in 4 U.S. adults report current back pain, with 13–14% describing pain that lasts at least two weeks.


Why Back Pain Is So Common

Most back pain is what clinicians call nonspecific low back pain—pain without a clearly identifiable structural cause. Lifestyle and movement patterns play a large role:

  • Prolonged sitting and poor posture tighten key muscles and increase spinal stress.
  • Weak core muscles can force the lower back to take on more load.
  • Low activity levels are linked to both onset and persistence of pain.

Recent research even suggests that simple lifestyle habits like walking more — about 100 minutes per day — may significantly reduce the risk of chronic low back pain.


The Case for Exercise

One of the strongest pieces of evidence we have is for exercise therapy. A major review that included 249 clinical trials found moderate-certainty evidence that exercise is more effective than no treatment or usual care for reducing pain in people with chronic low back pain.

Exercise can help by:

  • improving spinal mobility
  • activating supporting muscles
  • enhancing muscle endurance
  • reducing stiffness

Even modest activity — like walking, gentle movement, or strengthening exercises — can make a measurable difference over time.


The Value of Physical Therapy

Physical therapy is one of the most evidence-backed non-surgical treatments for back pain. Early, guideline-based physical therapy has been shown to influence treatment patterns and may help reduce unnecessary imaging, opioid use, and invasive procedures when implemented correctly.

A randomized clinical trial reported that back pain accounts for a large share of physician visits and healthcare spending, and guiding patients into early physical therapy pathways can impact long-term outcomes.


Proven Exercises You Can Start Today

Here are three exercises backed by physical therapy practice that we use with patients at both of our clinics:

1. Cat–Camel Mobility

A gentle way to move each segment of your spine and reduce stiffness.

2. Modified Dead Bug

Strengthens the deep core without placing strain on the lower back.

3. Hip Hinge / Glute Bridges

Targets glutes and hips to offload stress from the lumbar spine.

Consistency matters more than intensity—that’s why we focus on movement patterns you can repeat daily rather than occasional bursts of exercise.


When to Get Expert Help

You should consider a physical therapy assessment if:

  • your pain lasts more than 1–2 weeks
  • pain limits activity or work
  • pain is recurring or worsening
  • you’ve tried rest without improvement

At Progression Physical Therapy of Princeton and Progression Physical Therapy of Somerville, we tailor programs based on your movement, strength, and daily goals. Our clinicians use hands-on care, personalized exercise, and movement retraining to help you reduce pain and get back to the activities you love.


Final Thoughts

Back pain doesn’t have to rule your life. With the right combination of exercise, movement habits, and targeted physical therapy, most people can reduce pain, improve function, and enjoy a more active future.
