Running can be beneficial to the lower back, but overweight runners may experience discomfort from running. Luckily, there are ways to alleviate and manage pain so you can continue running comfortably.
As you become overweight, your lumbar spine curves excessively forward. This places additional strain on your lower back muscles and may result in spinal degeneration and herniated discs.

Muscle tightness
Tight muscles can make running more challenging and increase your risk of injury, as well as cause imbalances in running gait and biomechanical movement. To avoid muscle tightness, it’s best to maintain an established core by gradually building distance and speed over time.
Your muscle tightness when running may be due to lactic acid build-up in your muscles or due to poor foot mechanics or an underperforming core; consulting with a physiotherapist will help identify its source and treat accordingly.
RunningPhysio’s physios advise visiting your physician if your back pain persists even with rest. This could indicate bone-related issues such as arthritis or discogenic pain (caused by herniated or bulging discs). You may require physical examination and imaging tests to pinpoint its source; symptoms could include radiating leg and hip ache, limited mobility or pain when bending forward or tilting your head to either side, as well as asymmetric tightness.
Poor posture
Poor posture is a prevalent issue in America, whether we’re slumped over our smartphones or just sitting awkwardly. Yet it goes beyond being simply unattractive: over time it can cause neck pain, back issues, and other health complications that affect us physically and psychologically.
Your spine consists of small bones called vertebrae that connect one another in order to form a natural curve, helping evenly distribute weight across your upper body and allow you to stand with an erect back posture.
Over time, poor posture can weaken and shorten the length of muscles supporting your spine, forcing deeper supporting muscles to compensate for lack of support from shallower ones. Muscle fatigue may even cause misalignments to your spine that increase risk and discomfort when running. A strong core muscle can help protect against this, as can regularly doing exercises designed to strengthen lower back.
Poor biomechanics
If you are overweight, your musculoskeletal system may begin compensating for extra stress by altering your running biomechanics and placing undue pressure on the lower back. Over time, poor running mechanics can place unnecessary strain on it.
If your core muscles aren’t strong enough to support the spine, the facet joints in the spine and sacroiliac (SI) joints at its base may become damaged, leading to problems in these important structures that help transfer forces between your upper body and legs when running – dysfunction can cause pain in both lower backs and hips.
If this sounds familiar, seek the services of a qualified physical therapist for an in-depth evaluation from head to toe. An expert can identify and correct issues such as forward lean or uneven stride which could contribute to lower back pain. With gradual training programs designed specifically to restore biomechanics and reduce overuse injuries.
Overuse injuries
Overuse injuries result from repetitive motions like running. Your muscles and bones experience constant strain when you run, placing an immense strain on both structures.
Over time, stress causes muscle fatigue and changes to your joints and ligaments, potentially leading to overuse injuries that affect not only your back but also other parts of your body.
Your lower back (lumbar spine) consists of five bones called vertebrae connected by ligaments and tendons, and each with discs to cushion movement of your body. Herniated disks may occur when jelly-like material within a disk pushes its way through its outer lining to press on spinal nerves causing lower back pain as well as numbness or tingling sensations in your legs.
To prevent overuse injuries, always warm up with walking or jogging before beginning any workout, then stretch gently afterward. Proper footwear is also crucial – make sure your running shoes offer shock absorption as well as being tailored specifically to you.
