Lower back muscle pain after squats: what to do

The lower back helps control the trunk while the hips and knees bend. A sudden change in load, stance, depth, speed, or fatigue can increase demand on the back muscles. Muscle Strain, Myofascial Pain Syndrome, or Non-Specific Low Back Pain are possible explanations. Facet Joint Syndrome, Sacroiliac Joint Dysfunction, Spinal Stenosis, Herniated Disc, and Lumbar Spondylosis may be considered only when the broader symptom pattern supports them. Pain after squats does not by itself identify a particular condition.

Set aside heavy squats and painful variations for now, but keep easy movement if it feels comfortable. Review bracing, breathing, foot position, hip control, and whether the weight shifts during the ascent. Restart with a lighter challenge and a smaller range, adding demand only when the previous level stays comfortable during and after training. A physiotherapist or qualified coach can observe the movement and help separate a training error from a medical problem.

Seek urgent help for new leg weakness, numbness around the groin, bladder or bowel changes, fever with severe pain, or pain after a serious fall. Arrange assessment when symptoms spread below the buttock, repeatedly stop training, disturb sleep, or fail to improve with activity modification.

Ask whether the pain behaves like a muscle problem, whether you should change squat depth or load, and which exercises can maintain leg strength while the back settles.
