The fifth lumbar, or L5, is one of the vertebrae in the lumbar spine. While L5 is a bone and can't be directly exercised, you can work the muscles around this vertebra. Exercises for the lumbar spine may help relieve back pain.

Your spine is the axis of the body, protecting your spinal cord and the nerves that control sensation. It also provides structural support for your upright posture and in doing so, supports about half of your body weight, explains Cedar Sinai.

The human spine contains 33 bones or vertebrae, at birth. By the time you're an adult, you have just 24 vertebrae because lower vertebrae fuse during the normal growth process.

Seven of these bones are located in the neck, or the cervical spine. Another 12 bones are right behind your chest, the thoracic spine. The final five vertebrae sit in the lower back and are known as the lumbar spine. The fifth lumbar vertebra is at the very bottom of your spine, right above your sacrum and tailbone.


Fifth lumbar vertebrae pain and lower spine or back pain, in general, is quite common. The National Institute of Neurological Disorders and Stroke reports that about 80 percent of Americans will experience low back pain at some point in their lives.

Fifth Lumbar Pain

Lumbar spine pain may occur due to disease, nerve inflammation or irritation, injuries to the bones or soft tissue, abnormal movement, infections or tumors. Often these causes lead to chronic back pain, defined as pain that lasts 12 weeks or longer. Exercise can offer some relief, but you may also need other interventions, so be sure to talk to your doctor and follow her advice.

Acute lumbar spine pain may result from an injury, accident or age-related changes in the spine. If you bend over quickly or twist to lift something heavy, you can pull a muscle.

Lumbar back pain can show up as sharp and piercing, but when it becomes chronic, it is usually dull and aching that radiates to your buttocks and feet. It's often most intense after you've been sitting for a while, and can be at its worst when you first wake up in the morning.



A sedentary lifestyle makes you more vulnerable to developing fifth lumbar vertebrae pain, as well as pain in the other lumbar vertebrae. This is especially true if you spend most of the week getting too little exercise but work out hard on the weekends, says the National Institute of Neurological Disorders and Stroke.

Exercise for the Lumbar Spine

You can't exercise a vertebra, but you can strengthen the muscles around the fifth lumbar vertebra to lessen the likelihood that it will lose integrity and cause pain. When you build up the muscle to support the fifth lumbar, your reduce demands on this part of your spine. The fifth vertebra takes less impact and stress daily.


Research published in Healthcare in April 2016 notes that a general exercise program that combines strength, flexibility and aerobic fitness is beneficial for rehabilitation of chronic low back pain.

A strong core supports the lumbar spine, so core exercises may help. Improving flexibility in the muscles, tendons and ligaments in the back helps improve your range of motion in the low back, including the L5 vertebra. Aerobic exercise increases the delivery of nutrients and blood flow to the low back, healing the area around the fifth lumbar vertebra.


The spring 2014 edition of the ​Ochsner Journal​ published research showing that resistance training may improve back strength, flexibility, endurance and balance. It also increases the integrity of connective tissue within the muscles, joining cartilage, ligaments and tendons. Furthermore, resistance training may help increase bone mineral density, discouraging brittle vertebra vulnerable to fracture.

The ​Ochsner Journal​ review explains that both core stabilization exercises and lumbar extensor strengthening are effective at strengthening the lumbar spine, especially the area around the fifth vertebra.
